    My Job: building 4,400hp engines

    Hey guys, not exactly automotive but interesting none the less.

    I work for the only non-manufacturer ran General Electric locomotive overhaul facility in North America and I figured I'd share a few pics of some of the cool stuff I get to work on.

    I mainly work on GE 7FDL16 series engines. They are 10,700CID V16s rated at 4,400hp/20,000ftlbs@1055RPM. Each locomotive is rated at ~140,000 pounds of tractive effort(pulling force.) Total locomotive weight is 400,000lbs.

    This is a complete engine setting next to the alternator that will bolted to rear of the engine and provides the power necessary to turn the traction motors. Combined weight is ~65,000lbs.

    This is just the bare block. The holes in the top are where each Power Assembly sit. The square holes in the side provide access for inspection/ repair.

    This is the crankshaft. It is ~11 feet long and weighs 4,200lbs.

    The pistons are a 2 piece design where the crown and skirt are bolted together. Combined weight of crown and skirt is ~50lbs. This particular piston had a failure of the wrist pin causing damage to both the skirt and cylinder walls.

    The turbochargers weigh 1,900lbs and are designed to provide 36psi of pressure in two separate 11ID intake manifolds.

    Here are a couple pics of the turbo mounted. One from the front, one from the rear and one of just the exhaust manifold.

    The pics from the rear is obstructed on the left by a power assembly and on the right by a water to air intercooler.

    I love working on this stuff and if you guys have any questions I'll be happy to answer them to the best of my abilities.

    Awesome pictures.

    Sure. Each cylinder is designed to, essentially, act as if it is an entire engine. The valves, cylinder walls, cylinder head, water passages, piston and rod are all contained in one unit. That unit can then be installed into the frame. That means if one PA has a problem it can be replaced without disturbing any of the other PAs.

    This is the jacket that contains the valve train, cylinder liner, cylinder head and the piston/rod slides into

    There are two different connecting rods used. A master rod and articulating rod(art rod for short.)

    Master rods resemble automotive connecting rods and the big end goes around the crank throw. This master rod came out of an engine I've been working on the last couple days. The turbo ate the compressor seal and then began sucking oil out the crankcase and then the engine oversped. The engine is supposed to turn 1055rpms and this one ran 1500rpms before finally sucking all the oil out of the oil pan. The engine burned through 400 gallons of oil in roughly 90seconds. The piston crown seized in the bore and broke away from the skirt.

    The art rod bolts onto a pin at the base of the master rod

    That is seriously cool stuff... I do have a question - you mention a traction motor. Does the engine actually just provide power (electricity) to the motors - and the motors drive the train? If so, is it so you can have better control over the speed?

    Yes, the engine just provides the juice. In 8th notch the alternator provides 2400 amps and 1200 volts of electricity. There are a couple reasons for the electric motors. The main reason is that an electric motor can provide insane amounts of torque at VERY low RPMs.

    I've never witnessed one actually let go completely.
    I have seen what's known as an "air box explosion." That's when fuel or oil oil vapor fills the intake manifold and a valve issue allows combustion to enter the intake manifold and ignites the vapor. That's a very scary scenario because the intake manifold(air boxes as we call them) are at chest level and literally 6" away from you when you're inspecting the engine when it's running. I've seen that happen twice, luckily no one was standing near the engine when it exploded. I've had a turbo blow out an impeller seal and dump ~40 gallons of oil on me. Luckily that happened immediately after starting and the oil was still cold.


    Most of the work that gets done at the shop is EPA mandated maintenance but there's almost always at least one catastrophic failure in the shop.

    This is cool stuff man... I work for metro-north railroad and deal with p32 genesis locomotives, well I use to now I'm in an office but I know pretty much exactly what your talking about. Except the actual engine break down. I've seem the p32 genesis motor up close before and its a monster!

    Very cool indeed my friend. I have always been a train nut, and I use to have a layout, in HO, that was almost 1/2 mile long. For real, until I moved and then I donated it to the WPMRR. That is the Western Pennsylvania Model Rail road club on 910.

    Cool pics again, I just wish I had some of our diesel generators from the nuke. They made that engine look tiny. The con rods were about 5 feet in length.

    That's awesome man!!!
    I've never worked on a p32. From what I've heard they're essentially a 12 cylinder version of the 7FDLs.
    I'll try to snap a few pics of the new 7HDL engines, or the Evolution series as GE calls them. There's a couple in the shop now with broken cranks lol

    The only problem with the pictures that you posted is that you need something in the picture for a frame of reference. I would bet that these items are much larger than most envision.

    You're right. I'll try and get a couple scale pics. The pic of the turbo mounted on the engine has a tool box on the left side of the pic but that's not that great for scale.

    So it takes around 4 locomotives to move a train?

    Most trains have 4 locomotives that provide power, however I think the way I worded it may have lead to a misunderstanding. Locomotive and train are different things. A locomotive is the unit that has the engine and provides the power where the train is the locomotives and freight cars combined. Trains weigh millions and millions of pounds. Even though the locomotives only produce 140,000lbs of pull they can still move millions of pounds. Its the same concept as a car that weighs 3Klbs can be moved by an engine that makes 200ftlbs.
