What is a good source of information on US Army railroad equipment? The locomotives are well documented but the rest of the equipment is not.

google is your friend

There are more hits that turn up on it.

What I never knew is they had a trench railroad in Germany.
Some things you never know like during the Afghanistan War they used Cavalry in the mountains, not train related but a curiosity nonetheless, being resourceful for the circumstances. Vehicles/trains would have a tough time in the mountains but horses, sure.

I kind of took it to mean he was looking for manuals for the equipment. If the army bought 4 wheel Fairmont pushcarts, they probably had a half inch thick booklet to go with it. I haven't seen any other then the locomotives, but I do know a guy who was a railroader in the army, I wonder if he kept any of his books......

Probably a good thing to track down these books, they were generally very simplified and comprehensive manuals on equipment nearly identical to the civilian version.

Thanks for the lead but I have already been there, both on line and in person. Mainly what I am looking for are records of the maintenance of way equipment including cranes, spreaders, etc.
