During searches for Union Pacific passenger cars, I came across the horse transportation cars that were a part of the passenger fleets of various U.S railroads. I also came across a site offering a large number of HO horse transportation cars from UP, Santa Fe, SP and other western roads. Aside from O scale brass, have MTH, Lionel, or any other manufacturers offered the horse car in 3-rail? Also would be interested to see if anyone knows if there may be O gauge horse car wood kits available.
