Diesel electric locomotives are started in one of two ways:

1. Most commonly, an electric starter motor run off batteries or a pony cart.

2. Air power replaces the battery to turn the starter motor or, in some cases, air is piped into the cylinders to turn the engine. Once it was up to speed, fuel was introduced and the engine fired. This way is apparently obsolete.

Good information here: http://www.railway-technical.com/trains/rolling-stock-index-l/diesel-locomotives/

I've noticed that in the Chieftain's youtude tank videos a lot of tanks for in cases of a dead battery or no battery that they had compressed air tanks for starting

The T 34 had a compressed air starter.

Air start on the 4, 12-278a GM Diesel/Electric Generators I worked on in the Navy.  :old:



I'm 6'1" and that puppy was a good deal taller than I was! It had 12, 278 cu. in. cylinders, was 2-stroke with 4 overhead exhaust valves and piston port intakes at the bottom of the cylinders.
I might not last very long or be very effective but I'll be a real pain in the ass for a minute!

Big Boy just steamed 5 blocks from house, even standing 35' feet from the crossing, the heat was almost too much to bear for very long. Nice hearing a steam whistle in town for the afternoon.

Meh. You want to do something impressive shoehorn that into a Pinto.
If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or your arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that you were our countrymen.

Heat from what?  The ejected steam?

The boiler, it was pulling slow up a long hill.

Ever stood near a steam locomotive at operating temps?

I can't find the diminsions for the 12-278A GM Diesel ANYWHERE! I would love to know the Height, Width and Length as well as its weight.

More likely the firebox and/or smokebox.  The boiler is covered in insulation.

I figure any firebox that can produce 6300 hp at the wheels has got to radiate some extra heat from somewhere.

I was being general in the description, not everyone is foamer detailed.

You could feel the heat blast as the locomotive approached my location.

Yeah, the boiler is covered in insulation... but it by no means stops the heat from radiating. A locomotive that's been fired and working puts off a tremendous amount of heat.

I've been in the cab of a working steam locomotive and it's hotter than balls back there, as well.

From a 2008 trip to Colorado I took with Dad. Cumbres & Toltec line. Pic was at the river crossing on the north side of Chama, NM. Not a Big Boy. Not even close. Engineer said they run everything at pretty sedate temps and pressures to help with reliability and longevity. You could still feel the heat as it went by, though.

I have three of my Grandfather's books from his employment, other then a pocket knife and a pocket watch, the only things of his I have:







Some days even my lucky rocketship underpants won't help.


Bring me my Broadsword and a clear understanding.
Get up to the roundhouse on the cliff-top standing.
Take women and children and bed them down.
Bless with a hard heart those that stand with me.
Bless the women and children who firm our hands.
Put our backs to the north wind.
Hold fast by the river.
Sweet memories to drive us on,
for the motherland.

Cool!  Did you use a long selfie stick or just jump nimbly out of the way?

I've got my father's NYC Fire Department Certificate of Fitness ($3.00 fee) for being a welder from the 1930s but there's nothing in it of special interest except his photo.

The $3.00 would have been about $43.00 today if my arithmetic is correct.

Lagging noun-like versus lagging verb-like.
