- The SD40-2 is perhaps the most common locomotive ever made; but what's the deal with the SD40T-2? Why did they need a special one? What makes it a "T"?

Right when you went to start talking about the engine protector, I was fully prepared to be a pedant in the comments section lol. A couple snippets from me are all I have though.
1: The hot oil detector and engine protector both work by causing the governor to sense low oil pressure, which as you said makes it shut down. The hot oil detector is a thermostatic valve, (like a thermostat in a car or truck) which opens at, I believe, 215 degrees Fahrenheit. When it opens it dumps the oil in the governor's sensing line causing the low oil shutdown to pop. The actual valve for that is located in the main lube manifold going into the front of the engine.
2: You mentioned a sort of "limp mode" and actually even those old locomotives have something similar. When you look right above air compressor and towards the front of the locomotive you can see a water manifold. That manifold has three temperature switches in it (a normal SD40-2 would have four). The switches are labeled TA, TB, TC, and ETS. (A tunnel won't have a switch in the TC spot since they only have two fans.) That ETS (engine temperature switch) picks up at, again *I think,* 205 degrees. When that switch closes a bunch of electrical stuff happens and it "derates" in a sense. It basically changes your throttle notches to 1, 2, 3, 4, 5, 6, 5, 6. (in 7 & 8 it knocks you down 2 notches) the speed reduction reduces the risk of cavitation in the water pumps, and the excitation system reduces the load on the engine as well. Not anywhere near what modern electronic controls are capable of, but still a neat little "limp mode" even on those old engines.
So yeah, that's the pedant in me satisfied lol. Great video and definitely earned a like from me!
Also, I'm sure you remember me from last week and I did check and according to the source I looked at, our 5413 retains the number it had when it ran on the D&RGW, and the 5412 used to be the D&RGW 5391.
Well hell! That's awesome detail. The BNSF sent us darned white hats to the mechanical schools, but didn't cover any electrical side. I always wished I learned more. I just thought those temp switches were just for controlling the rad fans - I'll admit, when I saw all of them back there on 5401, I was confused seeing as it has fewer fans. That makes a ton of sense! Thanks for teaching me something today. :)
@Hyce777 No problem at all! I'm a locomotive tech by trade and the railroad I work for has a roster that's over half SD40-2's. And even the stuff that isn't is mostly of similar vintage (GP35, GP40, SD40)
I also have a literal electrical manual for the SD40-2 that I was given as part of my apprenticeship.
Edit: I've also had days where I was bored at work and would get out prints and spend time going through them to find out what makes things happen. (Yes I have heard I'm strange) I have a couple of sequences wrote out on my phone for reference.
@@CDROM-lq9iz
There’s nothing strange about knowing your job, especially when you get sent on a road trip to get the mainline cleared and traffic moving again.
I’ve had to go out on the road and change a CLS (coolant level sensor) on a C-44 AC without losing too much coolant, and it was still running when we got there, stopped on the main line, nowhere near a water source to refill the cooling system. The bad sensor wasn’t allowing the unit to load, and the remaining consist didn’t have the power to continue on the uphill grade without it. I put on a rain suit, some leather gloves, some thick neoprene oil changing gloves over those, a face shield, and taped all of the seems on that stuff closed with duct tape. I was able to get the sensor changed and only lost about 4-5 inches of water in the sight glass. Got er loading and on her way in about 30 minutes time, main line clear and open to more traffic.
Have a good day sir!
@ralfie8801 Thanks and I'm sure you had a hell of a time getting out of that getup lol. I don't think I've done anything quite that sketchy but I have had to manually put motor cutouts in on an SD40 that was blocking a yard track and an inbound was waiting on the main for them to clear up.
I've also fixed a couple loading issues with a hammer to the side of a contactor.
I'm sure stuff like that would make plenty of people freak out lol.
@@CDROM-lq9iz
Yeah, I put all that on because I didn’t feel like getting scalded with 210 degree water. It was a mess, but it all worked out in the end. Had to travel 25 miles to get to it.
I was hoping to see a piston going to space in the clip that played after the discussion of crank case overpressure
Me to
Lol yes me toooooooo😂
i fully expected it
Who DIDN'T expect to see that?
Same
Would love to see both 5401 and 3011 featured in a loco 360
3011 is unfortunately missing a ton of functional things. It got parted out prior to being donated.
@@Hyce777 Thats a shame, perhaps swap out 3011 for one of the Geese?
9:29 if you look most modern locomotive adopted the tunnel motor style cooling and intake system .
Take a deep dive also on the sd45x elephant ears was another attempt to do the same thing
@@Hyce777Anyway we could get a 360 of the tiny little gas switcher? Peewee I think you guys dubbed it.
@@Hyce777I just want to see what's behythe door on the engineers side just behind the cab.... In detail... So yeah! A 360 would be killer!!!
Hey Hyce....5401 was a good unit, Mars light and all. Operated her back in the late 70's out of Denver. She is an old lady now, and shows it. When she was new she was proud to be a leader amongst the GP30's, GP40's, and SD-9's, SD-40's, and SD45's in the stable. These were, as you know, used primarily on the coal trains to Phippsburg, and beyond...to Craig. They had a very eloquent style. Will always be my favorite locomotive type...(they could really haul...at the lower speeds), and the dynamics were easy to control. Mitch Pittenger (Road Foreman) was a buddy (god rest his soul), and we had some great times railroading together. Thank you for the look back into the past !!!
Cheers my friend! I bet you've got some great stories from your time on the railroad.
I’m a Rio Grande guy. I put in 43 years. Hate to say that I finished with the up. I remember when those units came online. They were beautiful.
The Rio Grande thanks you for your contribution to our railroad
I really really want to see more "Nerding out" with Hyce on an EMD locomotive.
It may not be Steam, but the BNSF story juices can start to flow and experiences as the camera films Hyce show and talk EMD locomotives with this SD40-2T.
The Colorado railroad museum is on the list to visit some day. I've always thought the tunnel motors were a great series and such a simple way to approach the problem.
I loved our SP tunnels. We had 45t-2s and regular 40t-2s. Crews would often brag about how good "9500" and "9400" were at pulling. Sadly the tunnels are all but gone, with the last one "4071" breifly going into the deadline before being returned for a short time as a new customer needed a dedicated engine. She found her way into a few more road trains as she came in on her 92 day and the customer realized a big 6 axle was too much power for them only to finally end up leased to a grain elevator after one of their workhorses went down. Its unclear if 4071 will ever return to our roster or will remain at the elevator the rest of her days.
Nearly all went to Brasil and worked meter gauge with ALL and some rebuilt for FCA as BB40t-2....
it’s cool to see old engines like this
645 c.i. per cylinder comes out to 169.1 L!!!!
I understand that that's not super surprising to most train nerds, but to me, somebody who is just learning about how diesels work, that is utterly astounding!
Great work, Hyce! Love the content.
Id just like to say Mark, im happy to see how much you’ve grown your channel over these 2 years. Ive been here since u started the original RO play throughs. Cheers to you, keep on rollin man.
Cheers mate!
Hyce: Do you want to see me go into nerdy details of locomotives in video form?
Everyone here: But that's why we're here, so obviously yes!
Also everyone: With the Hyce special touch of teaching train tech, who would want to miss out!
You're hilarious, that's how you send pistons to space. Awesomely put.
A 360 would be cool and I think maybe a 346 step by step once in a while would be cool to
I would love to see a Loco 360 on this locomotive!
Very cool video! The SD40T-2 has to be my favorite EMD locomotive of all time. My grandfather worked for the SP and worked with these all the time, despite there being no tunnels on the SP route through Arizona, although they did work Donner Pass and throughout the Sierra Nevadas. Said they were fantastic at what they did. After the merger, he also got to work on former Grande ones and on the former DRGW lines, including Moffat Tunnel!
I guess this design also helps in hot climate of Arizona? The cooler the air you blow through the radiators, the more efficient they are. Blowing hot desert air through isn't great, but it's better than hot desert air that's been pre-heated by everything that it passed before it got to the radiators.
I'm not sure what the difference in manufacturing price, running costs and maintenance costs are, but as these changes were not made standard for the model I suppose there has to be a drawback somewhere.
Was about to comment about how the SP developed the tunnel motors, but it looks like you beat me to it. 😁 That said, Moffat tunnel is no longer the second longest in the US, it's the third. Flathead Tunnel in Montana, built in the late 60's, is second longest at 7 miles. It was built to reroute the GN Hi-Line when Libby Dam flooded the original route.
Why didn't they just build a really long bridge? 🤔
Oh cool! So we're extra extra wrong. Lol!
@@realcanadian96 they wouldn't need a long bridge. They'd need a very steep grade to get above the dam from Libby, and then a lot of track along the shore of the new lake (which flooded an entire valley, lengthwise). A new route to the south and the 7 mile tunnel was apparently easier and less steep.
the dam and the realignment were done by the US Army Corps of Engineers, fun fact. those guys are no joke, they can build anything, and to pretty good standards
@@BandanRRChannel rack and pinion?!?!? It was right Infront of them!!!! Smh...
Yeah, this is an excellent opportunity to do a full, in-detail workover of the locomotive.
As a side note, I really enjoyed that you admitted you were incorrect and offered corrections. Shows your humility.
Nicely done Hyce.

Absolutely check it out! Thanks Matt!
You know, I was just asking myself last week if you had covered the museum's tunnel motor. Lo and behold I get this in my recommended! Beautiful explanation of the functionalities!
Our railroad has 3 tunnels, two of them still retaining the original Rio Grande livery! 5391 (now 5412) and 5413!
As a side note, sanding these things are a pain, especially if there are two of them back-to-back :L
I just love trying to reach for the sand hoses that have been set up for regular 6-axles and the occasional 4-axles when these long bois come in. Stretch Armstrong mode activated. And don't get me started on those long hood suicide steps .-.
Those SD40s may be old and outdated but there are very few locomotives that I prefer when it comes to flat switching.
They load way quicker than anything GE ever made, that's for sure, lol.
I preferred the SW1500s and MP15s for switching. The brakes are not that great on the Geeps and SD40s, especially if they have the independents turned down for remotes.
@@rjohnson1690we don't use remote locomotives, we have an engineer due to our yard design. All of our older locos have been sold or scrapped :(
@@Hyce777lol switch with any GE is pain, at least the new ACs (when we get them) are quite quick once they start to load.
GE units for the most part have better traction motors and stronger tractive effort. EMD units however normally load quicker,both DC & AC,which gives them road switching advantage. One of the only GE units suitable for switching are the ES44AC's,the throttle response is impressive. I completely agree about the SW1500's,minus the flexicoil trucks,and MP15DC's/AC's which were awesome switchers. The GP40-2's & SD40-2's were the last great units built by EMD without any major flaws. It's debatable nowadays on what's been reliable. I will personally note down that the modern GE units have incredible dynamic braking when it comes down to serious tonnage.
A tunnel story.
My dad fired for the B&O out of Baltimore, West End. The route west, the Old Main Line, winds it's way up a river valley, cresting the grade at a place called Mount Airy, Md. The line summits through a mile-long tunnel under the town. Not that steep, but for a train, gradient is relative.
The trick to firing through a tunnel is to have the boiler full, and the fire-box as hot as possible with plenty of coal. Before entering the tunnel the feed-water is shut-off, and no more coal added to the fire. With luck the train will be over the hump before water and coal must be added.
Often the water in the sight-glass would drop out of sight.
The story
The engine wasn't steaming well. Not only did it require almost constant feed-water, it was burning more coal than it should, and was filling the tunnel with exhaust.
Then they stalled.
My dad looked over at the engineer. The engineer was on the verge of passing-out. My dad suggested to the brakeman to get down and pull the pin, they had to get out of there.
He went over to the engineer, shaking him and yelling, "Give the brakeman some slack, we're cutting-off and getting out of here."
Tunnels and fuel-burning engines are fundamentally incompatible.
If tunnels had desires, it would be to kill humans.
I am sure that Hyce has a copy of "Rails that Climb."
The Moffat trains faced snow-shed hells.
That's a really dangerous situation to be in !
( sounds like in the llate 1930s or 1940s )
If you were headed Uphill, water would normally flow to back/cab end of boiler, causing sight glass to read high compared to a level loco... if water is below the sight glass and you are on an UP grade, then the front of boiler is running dry, and the water right over firebox top plate is thin too, which can lead to boiler explosion if you have much of a fire going.
But, at that moment, their immediate problem was a stalled engine and being 3 minutes from suffocating in a tunnel !!
About their only option was to set the air brakes on train, disconnect, and use what little steam was left in boiler to get the locomotive + crew moving toward fresh air.
This would have left a mess for the rail line... (hopefully no other train scheduled on that track soon)
Rail boss would have needed to send another loco+crew to attach to the train from bottom end, release the brakes and take cars back downhill to siding or rail yard... possibly split into smaller load, then send again in pieces.
Sounds like it may have blocked rail traffic most of the day, but I'm glad nobody died.
The Ringneck and Western railroad out here in South Dakota has a tunnel motor running on their line. It looks a little silly being there no tunnels, but it's a cool piece of railroading history.
When you said send a "piston to space" I was a little disappointed when that next video clip, wasn't an example of that happening.
Love the new camera angle. I always wondered what the POV of Hyce's coworkers were XD
My dad was one of the lead design and manufacturing engineers for Motive Power out of Boise, Idaho up until just before they went bankrupt from poor account management. I can’t wait to show him your channel. He will tell anyone who will listen that “working on choo-choos” was the best job of his 45-year career.
Would love 360 video on SD40T-2
The DMIR ended up buying several of the SD45T-2 rebuilt into SD40-3’s.
You know, seeing you next to the loco Hyce, reminds me of how huge the US equipment is! Our stuff only go as high as the nose of your locos. That's one reason I want to visit the US, just to enjoy the size of the trains!
We have a pair of these in my home terminal in Fond Du Lac Wisconsin for CN. We use them as shover power, and I always wondered why they have a huge open space in the back. Thanks for finally answering that for me!
Please do a locomotive 360 on the tunnel motor and maybe 683 too
Would love to see a 360 video of it. The sd-40 and dash 2s are amazing locos and so much fun to operate
Those old converted rail trucks (car/vehicle) are amazing... Would love to see all the trains but those are super interesting , ive never seen any that old and they look in really good shape
Former EMD mechanic here, once we got a call from a customer saying the engine shut down and wouldn't start back up. And they said it wouldn't stop beeping for hours and just couldnt figure it out. We went out there to a geep and turns out the only problem was the governor button was out. Pushed it back in and problem solved 😂 topped off the water and the oil to make sure and checked its vitals. Everything was all good!
I lived in Tolland, CO for 13 years, which is right next to the Moffat Tunnel. I instantly recognized some of your video footage. I've seen so many trains going through there it's unreal, and I've probably seen that locomotive going through the valley too (lol). The locomotives going through put out so much diesel exhaust that they usually stop when they find out from other trains in passing that there are stowaways on the train cars. They'd stop the trains and call the local sheriff's office (me) to come out and remove them. Not so fun when it's -40 F outside. The Moffat Tunnel has a giant locomotive engine along side the tunnel entrance, which forces air in the opposite direction the train is traveling. This keeps the area around the locomotive from being consumed by the train's exhaust, and keeps the engineer and conductor from getting suffocated by the exhaust. When the tunnel fan engine fires up, it is so loud the sound fills up the entire valley to the east with the siren-like sound of the fan and engine.
"You do not want crank-case overpressure... That's how you send pistons to space."
Watch out, Hyce! Jebediah Kerman will be looking into piston-launched rocket technology next!
Your videos are awesome. I love the content. 👍🏼
Great video. The production value reminded me of those "All About Trains" VHS and DVDs from my childhood
I’m willing to wager Baby Hyce had those videos too……
I’ve always heard that the point of the tunnel motors wasn’t really to keep cool inside the tunnel, because pretty much all air in the tunnel gets hot after a little bit. But rather it was to cool down faster when it was outside the tunnel, so that it’s ready for the next tunnel.
You know darn well that we'll watch a Locomotive 360 of literally everything, even those railmotors, a hand-cart, heck, a tool dolly you left across the tracks in the shop. (Save that film for 1st April.)
I would love to see a 360 video of that
If you can find the book,,very rare, titled the "Mack Railroad" the Gilsonite Route. It describes special built Baldwin locies articulated in the middle to make the sharp curves up Baxter Pass in Mack Colorado to Bonanza Utah to haul Gilsonite back to Colorado. When it shut down both Locies disappeared. One was found some 20 years alter in Honduras. From what I understand it is still there, on a side track covered with Jungle groth. Only two of the exotic engines were made.
I remember seeing these as a young kid (in SP livery) and noticing they looked different. It wasn't until a couple of years ago I learned what they were. This video does a great job of showing the equipment that makes it a tunnel motor.
Just found your channel I really enjoy the videos. I was a locomotive engineer for Conrail and then CSX. Best most fun job I ever had.
I love these videos, this is stuff I would have never been interested in since I'm more of a continental european electric loco guy but your presentatnion manages to make this stuff incredibly interesting.
Was noticing 5401 in the background during the cow catcher video. Saw a DRGW diesel behind you and thought 3011 until I saw the standard EMD cab then the road # and was like oh new acquisition,neat.
Second the idea of a 5401 3011 double loco 360.
Would love to see 5401 in a Loco 360 piece. And considering it’s recent retirement, run again. (As Jeremy Clarkson would say “how hard could it be??”)
Can't wait for them to offer Hyce the job of project management for restoring that loco and him to just shut down and have flashbacks.
you are literally one of my fave people to watch talk about things, not for the topic (although interesting), but for the way you structure the video, the method, the context, the sass and the wit. you truly are an intellectual pleasure x
A loco 360 video of this locomotive would be great.
Fun fact:
Prior to initial tunnel motor development, SP had initially tried to combat the tunnel overheating / de-rating problem by experimenting with a "tunnel curtain". This is circa 1969. Essentially, a large curtain of heavy canvas cloth, draped and "sealed" off the tunnel's opening, which was rigged to a mechanism that would vertically roll up the curtain when approaching trains would trigger trackside relays. The scheme worked so-so, but SP scrapped the idea when a failure in the system saw an SD push its way through the curtain, as well as the cost of retrofitting tunnels. The tests were performed on the west portal of Tunnel #7 on the Cascade Sub. It was after this series of experiments that SP finally laid down the gauntlet to EMD engineers and said, essentially, "you need to build us a modified SD40 that can adapt and live in our long tunnels."
Curiously, today, the UP has a lot of the similar problems on that sub with de-rating or shut downs. Everything old is new again.
I love watching your videos and as a helper in a maintenance shop the standard SD40-2 is 68ft 10in, where the SD40T-2 is 70ft 8in the Locomotive is slightly longer to accommodate for the rear tunnel radiator
Here in Vermont, we have one of Southern Pacific's SD40T-2s still running. NECR 3317, built as SP 8256 in April of 1980 is still used almost daily across the NECR system. sadly NECR Repainted it to the standard boring orange and black G&W scheme, but it sure is fun seeing such a unique engine here in the far northeast. I am hoping for it to stay for a long time, however it sounds like NECR will be receving GE -9 power sometime this winter and either selling or scrapping a lot of the classic EMD fleet including former a DMIR SD9 (NECR 1750)
This locomotive went by my house all the time as a kid on 62nd and carr street. My grandfather was a switchman for rio grande for decades and i used to go down to the yard to hang out back in the 80s and 90s and watch him kick cars over the hump. He retired after union Pacific came in. I actually picketed with him back in the early 90s. I miss seeing these rio grande locos going by. Every now and then youll see and old dilapidated switcher go by in arvada. I can tell without even going outside, by the wheezing chugging sound of those old emd diesels.
Another banger of a video from Hyce. I’ve never been happier to be subscribed as I have been lately. Fantastic content. I’d thoroughly enjoy a 360 video of this loco, and more!
Another great, interesting, and informative vid, Hyce. Keep 'em coming and I keep watching. I really enjoy your channel .. thanks.
We have multiple tunnel motors in service on the former DM&IR, now CN, pulling taconite trains.
What's up, I work on the moffat sub today. I can tell you with 100% certainty that we all wish our distributed power were tunnel motors. They choke themselves out in the tunnel district all the time with the high air intake
Would love to see 360 on 5401 I have always loved the tunnel motors and would enjoy seeing more. Thank you hyce for what you do and being an amazing person that shares their passion with the world around them
I had a family friend on my dad's side that worked for D&RGW in the shops, he worked on quite a number of diesel locomotives ranging from your First Gen. EMD's (GP7's, SD9's, F units), to late Second Gen. EMD's (SD40T-2's, SD45's, SD50's). I think he might've done some work on 5401 in the shops before retirement.
I was actually learning about Grande 2nd gens like this just before this came out! Keep up the great work helping common civilians learn about this great industry!
As much as i appreciate the videos you do on locomotives, i most definitely appreciate the honesty you have when it comes to mistakes! Very cool!
That's a neat bit of unique tech.
Far away shots alongside the close shots to maintain perspective is awesome, thank you!
I just rode the Amtrak California Zephyr through the Moffatt tunnel last week on my way home to California. 10 minutes for the 6 miles and no moving between cars through the tunnel. I didn't notice any particular diesel fumes either.
The section between Denver and Glenwood Springs or Grand Junction is a great trip for the exceptional scenery.
Atlas shrugged had a good chapter about diesels and tunnels and mayhem of sorts. Great book centered around a railroad company
Loving the channel information and content thanks for the uploads
I noticed that the Tunnel Motor has the extended dynamic range blister instead of the normal version. That would make an excellent addition to your video here
As a kid growing up on Denver, in 4th grade nearly 40 years ago now, I built a replica of the Moffat Tunnel for a school project. The model split open to show the track going through the mountain.
I've never forgotten that one. Especially since I use to visit the tunnel frequently as a kid.
those engine door labels are some prime "Don't Dead, Open Inside" material.
100th liker, good work Hyce.
Its nice to see some Diesel discussion in this land of Steam Love. I'm certain you guys could get 5401 running again if you got a use for it.
Could you make a video on Wig Wags possibly?
That's a good idea!
@@Hyce777 Maybe a whole video on the history of grade crossings and their equipment? Where they came from, how they work, hoe effective they were, etc.
@@brucethebatcat5084 well uh, aside from the legend (The Delhi wigwag) what other railroad crossing signals are at the Colorado railroad museum?
Id love to stand behind one of those cooling fans at full tilt.
I love this video because I've always understood how a tunnel motor operates, but I've never known how it's all put together to actually do the cooling. And yes, please do a Loco 360 on it!
So nice to see American history brought to life.
When I first started on the railroad I hit my shin on the rear ladder step of a RioGrande tunnel motor. Never forget the pain of that experience
"can't be that hard" - This is how all projects start :D
Mark, YES please continue the tour with a 360
video on the CRRM’s newest acquisition 5401! I know very little about diesel choo choos so this latest video furthered my understanding of them. Love that the original paint scheme survives. What a gigantic locomotive for sure. The huge cold air intake was ultra OMG, almost like a screened in porch. I was thinking a few lounge chairs and could provide a nice shady area during the hot summer months 😂. Opening up the compartments and pointing out important components and what they do was not only fun to see but such great learning moments as you discussed the details. And as you say, Mark, it’s so all about the details! Congratulations to the fab CRRM on their latest rolling stock collection acquisition. And most importantly many thanks Professor for yet another excellent learning video and as always cheers to you!
The wide shot really shows a sense of scale on those engines
I spent a lot of my childhood at that place. My Uncle Jim Dutton helped to build the layouts in the basement.
Awesome show, I always wondered how these worked, very nice and thorough explanation !!
Pretty closing music! Thanks for your expertise Hyce!
You guys are a crack up.... Great info and love the delivery of the video..... 🤙
Growing up in Colorado Springs in the 1980s and early 90s I remember seeing these tunnel engines moving through town - including once on the Rock Island branch extending east of town.
As someone who remembers 1980, hearing you say "1980 is not that old" was a balm to my soul :)
Was just thinking about tunnel engines used by SP, and bam! up pops your video! Thanks for taking the time to show us exactly how the “T” engine concept worked.
Great video!
Tunnel Motors just make me want to visit the Colorado Railroad Museum more, and I'm already planning a trip there.
Would love to see a 360 video this. These old diesels have a lot of character.
Great video look at one of my all-time favorite locomotives. Thanks for creating it. 👍
You are great at explaining trains! Awesome video
Awesome video. Thanks for explaining the differences.
This is some of the most fascinating content imo. Nerds love to see how stuff works!
crank case over pressure: Want to go to space?
A HUge Big hanx for an AWESOME explanatory doccu info about the big iron we ALL LOVE..love and respect from denmark
Hyce once this Loco is Finished please make sure you bring us a long for the first starting in 15 years ok I love this kinda of stuff getting old engines running love
Very informative and well explained. I really like your enthusiasm and gestures as you teach your viewers the fine points of the great subjects! All in all, your interest makes us interested😊. Good work, my friend and many thanks❤
Great stuff! SD is my all time fave in diesels n ya learned me some things Hyce! Cheers from Santa Cruz ca
Thanks Mark another informative video, i've learned so much more on one of my favorite subjects, TRAINS !
I just worked on ex SP SD40T-2 CORP 4075 yesterday
Wow Hyce ! Thank you so much for this clip. Im building a 1/11 scale version of this locomotive and your video helps me A LOT ! Thank you so much for a close look into the rear of a Tunnel Motor. Btw a 360 video would be super nice !
Cheeers from Germany
Love seeing people talk about the things they are passionate about, no matter the topic.
"You, breathing your own fumes in an enclosed space, you would shut down too" a porta potty in mid July came to mind.
