When we were kids, there was and still is a railway line at the top of my Mothers garden near Cannock in Staffs. My friend was a spotter and while I never went that far, I enjoy watching trains myself. He lived further from the line and to claim a loco as seen he had to race upstairs and look out of his bathroom window to see the roof of the loco passing behind the houses over yonder. If I got the number I’d pass it to him. This was every school lunchtime. On one occasion I was cutting a sandwich and a loco came past light engine running down Wyrley Bank. It was basically just rolling down the bank making little noise as it approached. It was early spring and I easily got the number through the bare branches of the Hawthorn bushes at the top of the garden. Even so it caught me by surprise. 37 003. Odd. Not seen one of those before along this line. So anyway, I headed back to school and linked up with my mate on the way. “Did you see the loco that passed?” “I didn’t hear one.” “It was an odd shape I’ve not seen before on this line. 37 003.” He went BONKERS!!” “Naaah. You don’t get those along here.” I described the shape of the loco which fitted the number but even so he was well annoyed and for years afterwards he still accused me of making it up. Still makes me chuckle. So I’m quite pleased the loco still exists and is being looked after.
In one word, COLD!! A diesel engine requires 2 things to fire properly, Compression, and heat. This is what pre-heaters or glow plugs do, they warm the air in the cylinder before it's compressed and fuel added. Normally the heat comes from the act of compressing the air in the cylinder, but on a cold engine as here, the white smoke is mostly steam, and the black smoke is unburned fuel. Have a look at the same locomotive, starting on a warm day, and you will see the difference.
Stone cold. Giver her half an hour. Nice easy start, all 12 fire up fairly quickly so the timing is good. Once the oil warms up, the governor will be able to function correctly, the engine will stop hunting and be able to tick over smoothly. Effectively the oil is so thick that the governor detects what it thinks is a massive overspeed, cuts the fuel then detects an under speed so dumps a load of fuel in, hence the revving,
on and emd u can change the power packs (piston,liner, head) with engine in situ, u dont even have to remove overhead cam as its to one side of the cylinder, just open inspection door in crank, undo big end, open top, remove head and few other things and lift the lot out so Im guessing they get changed more, also 2 strokes always sound more crisp.
@joha77johaa It is called "hunting" The governor is not reacting quickly enough when cold to keep the speed steady so revs go up and down . It is not load-idle, just the no-load speed not constant.
this Vid is at Weardale, access is weekdays only here as the operating companys staff have to be present, 003 is currently on public display at NRM shildon as part of a visit.
Yes, but Smiffy answered my question. I'm wondering why EMD's fire so clean while these engines don't. I'm curious to know the difference. Sounds like mostly just older technology.
the governer is controlled by oil pressure, when its cold the oil is thick and doesnt flow well causing it to rev up and down, there an example of a warm day start on another of my vids, to see the difference.
To be honest. It wouldn't be all that hard to implement an external heatsource to keep the oil even slightly warm whilst not in operation. Like what those ice truckers do or something?
adfgfds the generator used to provide current for the traction motors is energised to act as a motor. Refurbished units with alternators use a separate starter motor.
Why do these engines start like this? What is it doing when its shooting tons of smoke out like that? EMD engines don't do this, so it makes me wonder how these start.
Is access still restricted at wensleydale? for work on diesels that is, the steamers get access, more anti diesel facism like NYMR where the steam fitters even ignore u if u like diesels, millitant kettle lovers!!lol.
ITS ALIVE !!!!!!! What an awesome looking train

that is just....HELL FIRE
Great Vid
oh how i miss working on 003
I do sympathise with her: I'm just like that on Monday mornings at this time of year.
I like when these Deltics blow smoke rings at startup.

I didn't know the governor can detect the viscosity of the fuel oil?
Rune the governor works by oil pressure. Is the oil is cold and thick, it cannot react quickly enough.
Does the governor keep the engine from blowing up
How come it's only the 37 that hints like this? And even hot they still hint at idle
Love the smoke rings at the start
That IS something!
When you do winter prep work set it up to some huge back 🔥🔥🔥🔥🔥🔥🔥🔥🔥 fires and balls of flames 💥💥💥💥💥💥

Just let them warm up for 20mins, and they run very sweetly indeed! Remember, no pre-heaters on these, Very old school engineering from the 1950's....

That should be used as the starting trailer for carry on claggin 3!!
Yeah, the big cam loper
Sounds like an old Massy Hit n Miss...
What causes them to create such smoke starting up? Are the cylinders caked with something from an earlier run?
My mrs' Citroen Xsara starts like that.
How do they get all that oily muck off the rolling stock?
Did they start up like that from new?
Yes, but Smiffy answered my question. I'm wondering why EMD's fire so clean while these engines don't. I'm curious to know the difference. Sounds like mostly just older technology.
Cos these engines have basically been run into the ground
the governer is controlled by oil pressure, when its cold the oil is thick and doesnt flow well causing it to rev up and down, there an example of a warm day start on another of my vids, to see the difference.
no, it has a pretty massive electric starter.
yeah, dont let environazis get a hold of this vid. 5*
the main generator is used as a starter.
U know about diesel electrics right?
diesel turns generator, electric trickery turns motors on the axles.
so THATS how they make clouds?!
To be honest. It wouldn't be all that hard to implement an external heatsource to keep the oil even slightly warm whilst not in operation.
Like what those ice truckers do or something?
By cleaning it off.
10" bore x 12" stroke
that thing smokes like a kettle
Looks like Draxindustries' car failed its diesel emissions! So on a "crusade!" That will clear, typical EE cold start.
just as im having a can of coke :)
37414, its tin cans and razor blades now :(
környezet barát mozdony ennél még a gőzős is jobb volt
Do they air start? I'm just curious how they work.
adfgfds the generator used to provide current for the traction motors is energised to act as a motor. Refurbished units with alternators use a separate starter motor.
@@nigelterry9299 they have twin electric starters like on a car.
How large is a cylinder for one of these engines?
15.4 litres
Why do these engines start like this? What is it doing when its shooting tons of smoke out like that? EMD engines don't do this, so it makes me wonder how these start.
Are you sure emd ying yings don't clag oh hell yes they do!!!
Euro 0

Too Bad Diesel Engine
