Ed:
Thanks for the valuable info.
The engines are definitely in Mexico. No doubt about it.
Another thought, I know that military helicopters can carry a 105 artillery piece. So what about a tender or a light 4-4-0 that has been stripped down?
Maybe the engines can be disassembled at the remote location and shipped and airborned out as scrap. When is a steam engine not a "historical" artifact-- when it appears as just rusted various pieces of scrap...think about it.

ps: We are Americans and have a can-do attitude.
Think positively and creatively and just do it.
Don't you really love the challenge and the adventure?
