Here is my first completed dabbling in S gauge. I built these cars out of styrene, using Kadee 802 couplers and hi-rail wheelsets from American models. These cars, since they are articulated, won't go around standard AF 20" radius track, but that's all I had, so I had to put a straight track in between each curve section. The loco is an American Models GP-35.
More to come as I improve this train...
