I model the steam era, but am very interested in the many varieties of internal combustion rail critters that arose simultaneously with the automobile about 1900 and then operated widely on steam lines. The only one I have ridden was about 1980 on a Washington's Birthday "Coming Out" on the East Broad Top. I have passed the track of a tourist road I understood was running a repo of an Edwards car in W. Va., and heard of an EMC-St. Louis car operating in....Wisconsin?
The Strasburg for a while had around their shops a little rail car that operated on a line not far west of there. I don't
think the Strasburg was offering rides on it. The Cailfornia Western has operated various railcars, but neither time I was
there several years ago were they running (and California is a "fur piece") Where today are there tourists roads running gas electrics regularly, on weekends, or?? Is there a list published?
