Class 37003 restarting after some winter prep work

[VladimirCrimea]

Dibilniy start.

[arlosurgenor]

absolutely excellent!! listen to all the green wankers worrying about smoke!! I was an engineer for northern ireland railways on the "thumpers" and the load tests were a hoot!! sometimes the adjacent motorway was enveloped in clag!! Once and for all 1. clag is unburnt diesel 2. glow plugs wud need a huge amount of power on such large engines. 3. no, you cant convert to gas 4. we dont want to change them, thats why we preserve them, because we love them, and the clag..........

[JustinHansen6669]

@arlosurgenor, there you call it clag. here in the us we call it soot... and thats why i love listening to environmentalists bitching about Black smoke... its friggin soot (clag) the shit falls right back to the ground. no harm no foul, glow plugs out of the picture, eventually the heat from the compression will ignite and will create more heat to help the next time it fires on that cyclinder. i just love proving ppl wrong that dont know shit about diesel engines... seems same to you.. enjoy..

[joha77johaa]

please who can explain me, why the britan-diesel-engins after start-up are working frequently in load-idle-load-idle.??

in germany it is unable.

greetings from an engineer

[spentacle]

@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.

[joha77johaa]

@spentacle

many thanx to you ! Iam an engineer from Berlin. This cold - sound is in germany unknown.

We are heating up the engine cool-water above 60 Grad Celsius, start-up...and...thats all ! The engine runs immediately steadily :-) and 10 sec after start-up, you won´t see SMOKE ;-)

Greetings from Berlin

[nearport]

@joha77johaa They don't have to, there is a governor override which British loco owners seem not to use.

[joha77johaa]

are you sure it isn`t a steamer????

:-)

[teletubbykiller23]

man that engine is a growler!

[adfgfds]

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.

[smiffy1071]

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....

[adfgfds]

Do they air start? I'm just curious how they work.

[smiffy1071]

no, it has a pretty massive electric starter.

[adfgfds]

What causes them to create such smoke starting up? Are the cylinders caked with something from an earlier run?

[smiffy1071]

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.

[tpvalley]

the main generator is used as a starter.

U know about diesel electrics right?

diesel turns generator, electric trickery turns motors on the axles.

[adfgfds]

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.

[tpvalley]

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.

[chukostya]

Euro 0

[Andyhinds]

My mrs' Citroen Xsara starts like that.

[danlefou]

How do they get all that oily muck off the rolling stock?

[Andyhinds]

By cleaning it off.

[bronzeonion]

that regional railways 37 next to 37003 looks a beast

[antimosh]

37414, its tin cans and razor blades now :(

[bronzeonion]

I drank cola from a tractor, =[ lol

[iib8903]

just as im having a can of coke :)

[tgirljj]

so THATS how they make clouds?!

[produKtNZ]

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?

[antimosh]

Yes it would, but who would pay for the electricity?

[charlieb640]

Those devices are available...but they cost money to operate and purchase. So each locomotive department on each railroad make judgement calls as to which units are to be so equipped.

[cipmars]

How large is a cylinder for one of these engines?

[antimosh]

10" bore x 12" stroke

[cipmars]

That IS something!

[WhyAyeMann]

yeah, dont let environazis get a hold of this vid. 5*

[nostalgiabufff]

Dammmmmmmm....that thing smokes like a train!! =)

[slartibartfast69]

thanks Anitmosh, will checkout the warmstart vid

[slartibartfast69]

awsome vid, i've watched a few 37 engine starts and i wondered why the engines rev up and down when they are first started, is it some kind of governer to rev them up and down til they have warmed up a little? or is there a fitter in the engine room reving the engine up and down?

[antimosh]

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.

[type2thrash]

That should be used as the starting trailer for carry on claggin 3!!

[lou2cv]

Haha ! The smoke is going off under the loc too !

[tpvalley]

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.

[antimosh]

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.

[iib8903]

that thing smokes like a kettle

[cmeonthemove]

Love the smoke rings at the start

[37201xoim]

I do sympathise with her: I'm just like that on Monday mornings at this time of year.

[xtremewrestling4eva]

that is just....HELL FIRE

Great Vid

oh how i miss working on 003
