I think the design was to spread out the weight. Except for the engine sitting higher, and the front of the engine shimmed up upon the pony truck, the loco appeared to be normal. Maybe someone has a pic of it. The design had the drive wheels going forward, the set under them going backward, and the bottom set rolling forward. Kind of a Rube Goldberg-looking affair.You're referring to the Holman Locomotive. Developed in the 1880's, this design wasn't based on sound engineering practices but turned out to be a stock scam for the developers. Follow the link and scroll down to "Holman's Absurdity":

Not American, so off-topic, but I've always been partial to the Listowell & Ballybunyan Light Railway. This was a Lartigue-system monorail (with-- monorails tend not to be as simple as they sound-- three rails in its track). Its steam locomotives had two boilers, mounted (for balance) side-by-sidewith the driving wheels between them.
