The East Broad Top Railroad's "Silver Sightseer," a 3 foot gauge MOW motor car, was built by Fairmont with a model B engine as a stock class A6. The EBT added the shiny aluminum sides soon after its arrival to deal with the long EBT winters. The model B engine was replaced by a '72 Chevy Vega 4 cylinder motor in 1988 for increased reliability.
