It’s not for a train, it’s for a motorbike.



…. Just think, 2 of these in a V-Twin displacing 3500cc or 215 cubic inches! Yikes!....

Kick starting that puppy might send your kneecap up past your shoulderblade.
Ooomph....6" bore!

Kick starting that thing isnít an option I think they even considered. Due to the valve reliefs in the pistons, I think it may even be a high compression engine. Some cars donít even have a 3.5 liter motor in them. Thatís the craziest V-Twin engine I think Iíve ever seen anyone try and put together.

This is a piston from a diesel electric in a train. Probably a smaller early model to. They are bigger now. 5000Hp models.

I'd love to hear it at a lumpy idle.

The vibration would probably shake your eyes out of place, unless they put some type of HUGE harmonic balancer on the crank.

I had a brief stint working on natural gas powered engine/compressor engines offshore. Those engines were much, much larger then a train engine could ever dream of being. They had four natural gas powered starters and would shake the hell out of the platform when starting up.

People use to run away when I started one. Should it backfire, and occasionally they did, it could be heard for miles over the open water.
