TYCO's 245-series steam engine was first shown in 1973-74 as an 0-8-0 locomotive, rather then the 2-8-0 that would be produced later. This original model appears to be a typical worm-drive steam engine, the later 245-series Consolidation would be driven by a PowerTorque motor located in the tender of the model. After appearing as an 0-8-0 in 1973-74, the steamer turns to smoke and is absent from the 1974-75 catalog. The model number 245 is back in 1975-76, but now as a 2-8-0 Consolidation. The price for this ready-to-run steam engine with smoke was $33 in the mid-1970's.
