i have only been to the Galveston railroad museum in Galveston, Texas. and the Nevada railroad museum in Carson City, Nevada. i would love to go to steamtown and the California State railroad museum.
the one in Galveston is pretty nice. they have a good collection of equipment but i think they are running short on funds and volunteers. some of their stuff is getting a bit ratty looking. i wish i still lived down there so i could volunteer some of my time to help fix up their displays. if anyone lives in the Houston area and you have somespare time or spare cash, i think they could really use the help.
