Do all trains use the diesel engines to power electric motors?

Everyone I've seen. I don't think there would be any other way to deliver the torque necessary to pull multi-million pound loads without destroying parts every day.

SO, whats behind this cover?



If you guessed, the air passage way, you guessed right.

Those of you who are familiar with 2-stroke designs will understand what's going on here, and for those who don't...

A 2-stroke doesn't use valves for intake/exhaust. It uses ports that are exposed based on the position of the piston on it's stroke.

Now this is a very strange setup that I had never heard of until starting this Career. But these engines use a combination of intake ports on the cylinder, and exhaust valves on the heads to allow a turbocharger to work.



Also note, hollow block. Took me a while to figure out that the pipe shown is for coolant. Otherwise how the hell would these things not burn up? When I saw this setup for the first time I was awe-struck. Especially considering this is not a new design by any means.

I'll snap a photo of the top end tomorrow. Equally fascinating. A 2-stroke with valves, turbocharger, and camshaft? wtfsauce.

need moar cool train pics and train stuff

seriously, this shit is killer, i love seeing the insides and inner workings of these behemoths

During our outbound load test today after a routine 3 month inspection.

Every time we do this I just want to yell out, "GET SOME!"

I'm going to guess a train.

Is this the same turbo OP?

Ding ding ding. May not be the same exact model, haven't had the pleasure of seeing one outside of the loco yet.

We were working on the head end power unit (Generator that supplies 480v to the consist) and I figured I'd snap a couple off the Primary mover.

I'll add more photo's to this thread. This shall become my "everything is bigger on choochoo train's" thread.... Or something.

Here's the engine it's attached to.


MP36C loco. These engines are the coolest things I've ever seen. 2 stroke, turbocharged, diesel, with exhaust valves in the heads and intake ports on the cylinder wall.. Say that 3 times fast.

Do you need glasses, Will? Look at the OP's pictures again, yours is tiny compared to that monster.

The one I posted a pic of is more than 3 feet wide/tall (depending how you look at it.) . Perhaps its not as big as the OPs one, but this thing is huge, and yes it might be a centrifugal supercharger, I honestly can't remember. I took those pics 2 years ago. I thought it was a turbo, but there is a good chance it is a supercharger. And in my defence, at least its for a gasoline engine rather than a diesel.

I'll see your big turbo and raise you a big turbo...

Are you sure about that? Wikipedia says the engine in a B17 is supercharged, not turbo. Though thinking about it, it does say centrifugal supercharger, which is basically a turbo driven by the crankshaft, so maybe your picture is of a supercharger, not a turbo.

Interesting enough, the prototype B17 used an engine that was licensed to BMW who further developed it.
