"Stopping trains successfully since 1869. The genius of George Westinghouse."
I love the air brakes sound when they go into emergency!
This incident occurred on the Union Pacific Brooklyn Subdivision. The station is located 1,621 feet west of Mile Post 647. The two nearest crossings are Lincoln Street [FRA Crossing Number 756542Y] and Pearl Street [FRA Crossing Number 756543F] . This would be a southbound manifest. What more than likely happened was one or more cars lost air pressure, presumably due to some type of damage either in the airlines, or in the charging tank itself. When air pressure is lost somewhere in the consist, the entire train will go into emergency. That is all I have on this incident.
They love their distributive power units (DPU) out west. Mid-train and rear helpers are radio controlled from the head-end. This sounded like a fairly common "unintended emergency brake application", which can have several causes. The fact that the train was allowed to recover it's air and proceed suggests that either the problem was near the front of the train, and the conductor never had to walk all the way to the back (possible in what appears to be single-track territory, depending on what rule book UP uses, most likely G-COR out west - the second track appears to be a station siding), or something happened to momentarily disrupt the continuity of the train line, causing the emergency application. The fact that some brakes on the rear had not completely released when the train started moving is also not uncommon. The engineer is going by what his End-of-Train device is telling him his air pressure on the rear is to allow him to start moving (usually a minimum of 75 psi on the rear, with a declining rate of air flow). The brakes may take a short distance to completely release from an emergency application, but they eventually do.
Good catch !
Nice catch! Less bright sky allows more train to be seen.
Or learn how to use Manual Exposure.
The noise at 02:56 didn't sound like a train noise; it was sharper and clearer, something closer to the mic.

Way back in the day, I worked the extra board as a brakeman on mainline freights during summer breaks when I was in college. Between Toledo and Cleveland, the double-track Penn Central went through a bunch of small and medium-sized towns along the south shore of Lake Erie. One time we got an unusual stop signal that had us completely cutting one small town in half lengthwise. With trains in all the adjoining blocks we were boxed in-probably the reason for the unusual stop.

Back then, state law was that grade crossings could only be blocked by a train for a max of ten minutes. An angry cop pulled up to the caboose and was going to arrest the conductor for the violation. Our train boss told the cop that, also by state law, the train couldn't operate without him, so that would only make the problem worse. The cop finally just wrote him a ticket. Well, that's why conductors made the big bucks.
+Gene Rybarczyk Awesome story, angry cops rarely use their brain in situations like that. What the edited video does not show is the train stationary for about 35 minutes, blocking 3 downtown street crossings in a largish city. I read about one time back 2-3 years ago, UP blocked one of these crossings, and they were fined $100,000, it was for about 8 hours if I remember correctly - no idea why they had to block it, can't remember if they gave a reason.
+Railway World - Yeah, I remember us all being uncomfortable with what we were doing there, fully conscious that our disruption could delay emergency vehicles or have other serious consequences. And it wouldn't have been practical to try to break our train at all the crossings, either, because that would have tied things up even longer. At least it was late evening when it happened.

Truth be told, a couple of the PC dispatchers sometimes were known to get a little sloppy with traffic flow. Still, that type of jam-up was fairly unusual, what with the two-track main and miles of sidings, spurs and yards along a generally industrial corridor.
+Gene Rybarczyk That is very interesting!
i think it was a air hose dragging on the tracks
Gene Rybarczyk 😸😸
brillant catch that one massive train
The pop sound was an air hose that came apart. Heard that sound many times, and it always results in a new hose being installed.
Not really. One time I was working as a brakeman, a gasket came out of a set of airhoses, I just replaced it and went on down the track.
If they get an approach medium(flashing yellow) at a block and they are going track speed they the block, some engineers will drop the air to stop and after air comes back, they will run at 15mph to the next block which could be an approach signal.
buddy burton photography You can't go into emergency like willie-nilly... There is a reason it's called *emergency*. Going into emergency can cause wheels to lock up and get flats, and carries the risk of derailment. I think you are talking about putting the train in full service.
Four middle DPUs and no end helpers. I don't see that a lot. My record was in California on an oil train with 5 up front, 2 in the middle somewhere and 4 on the end. Over 200 tank cars of crude with one grain hopper and one boxcar on the very end at the helpers.
3:52 u can hear the air hose pop
Thank you I have not heard it the first time
This may be a dumb Q for those in the know, but I know the lead engines are all MUed together with the front engine in control of the others. But is the power in the center and/or end of the train also in the Lead MU loop or are they managed by other means?
Managed via microwave radio signals from the lead unit, I believe.
when it had to brake was it a car on the ground
Wow, nice catch and streetlamps
That's a shitload of crossings down there at 0:01 though, if you get time can you record them?
+realimbored668 Thanks, just luck. Forgot my tripod, but decided to record it anyway, good thing. Next trip I'll remember the pod, so a close up steady shot of all the crossings will be done. Thanks
Nothing was more upsetting than getting stuck at High St. when a long train was going through.
looks like one side of the line had a signal failure
UP mixed manifest freight with 13 GBRXs and 4 DPUs!
Great horn.
Loss of pressure can be from numerous mechanical things. Or the crew.
Amazing how much quicker it can stop with 4 DPU engines
Whoa, 4 mid-train helpers?! Is this common in Oregon?!
StarWarsTrains somewhat. The Eugene substation has extra locos most of the time
it is a rebuilt sd90
8252 is an ES44AC, not a SD90
Sounds like an air hose issue to me. You hear the hiss right before the wheels start squealing.
+LunaMizuki8806 I agree, probably an air hose issue, unlucky to happen in town, it was sitting there for over 30 minutes blocking traffic on 2 major crossings.
I like train videos on CZcams 👍
8252 isn't a sd90
Someone forgot to do a 1.33 and class 1 test, prior to departure
Failing to respond to the alerter causes a penalty brake application, not an emergency brake application. In a penalty brake application, the alerter makes a 26 PSI ( full service) brake pipe reduction and cuts the power to the traction motors. The engineer can recover by placing the automatic brake valve in the suppression position and moving the throttle to idle.
The train s goes into emergency at 3:52
I love the air brakes sound when they go into emergency!
Thanks
now it is a ES44AC
yes,it is also known as a C45ACCTE
Lot of wood on that train
never seen any wheels dragging????
i think they're talking about how the camera captures the bolts on the axles that seem to "lag" as they turn. i see the whole outside of the wheel keeps turning normally. i see this on all recorded videos, i believe it has to do with the shutter speed of the cameras making it look like the center bolts aren't turning smoothly.
I DID SUBSCRIBED TO THIS VIDEO ON YOU TUBE THANK YOU FROM DENISE TINDALL😂
nice capture of that what I call a "jump" train (two trains coupled together to form one long double train... as for the stop, I am guessing that the train had a "hot box" on one of the axles... a "hot box" is when one of the axeles bearings are bad or if one of the brakes are dragging causing the wheel/axeles to become overheated... when a "hotbox" is detected, the e brake will deploy as to prevent the wheel/axeles from coming apart and derailing the train...
+Dale Campbell
Yep that seems likely, a bad spot to happen though in the middle of town blocking quit a few level crossings for over 45 minutes, luckily it was towards the evening and not during rush hour !
+Railway World yes, well, we get those "jump" trains here in Reno Nevada and sometimes they stop on the crossings... try being in a taxi and get stopped by one of those "jump" trains... a real pain in the rear end if you ask me... but being a diehard train enthusiast, sometimes I just like to watch them go by...
+Dale Campbell It's not necessarily two trains. Probably just a heavy train that they threw helpers in the middle of. Sometimes trains will have Distributed Power Units or "DPU's" to help with the weight of the train on steep hills. These are basically normal locomotives but are being remotely controlled from the head end.
+Dale Campbell UP does it a lot.
+Dale Campbell A train being put into emergency has nothing to do with hot bearings. This was likely a hose separation that occurs with somewhat of a regularity when the trainline between the cars hangs down too far and snags something (usually a road crossing). We railroaders call this an "undesired emergency". The only other reasons a train would go into emergency under everyday circumstances other than a relatively minor mechanical failure (such as a hose coming apart) would be a derailment (not the case here), a "triple valve" on one of the cars not working correctly (we call those cars kickers or dynamiters), or a member of the crew placing the train in emergency to avoid a collision with something (also probably not the case here).
As a matter of fact, the last thing you want to do is put a train experiencing a hotbox into emergency, creating all sorts of unnecessary buff and draft in train forces which could exacerbate your existing hot bearing issue. You bring it to a quick, but controlled stop consistent with proper train handling.
also the Green light turned Red right after they Past it, ... .. .
Zraupp10 The point is...
does there have ti be point ?
Zraupp10 Well there is no point whatsoever about your statement. Your statement is just a fact, and has no meaning behind it.
Train number 2 rearended train number 1 that's what happened lol
Amazing how much quicker it can stop with 4 DPU engines
8252 isn't a sd90
