kscarbel Posted April 3, 2013 Share Posted April 3, 2013 As Americn cities transitioned from the street car to trackless trollies (a segment in which Mack was a leader) and transit buses, it was inevitable that the styling of the familiar street car weighed heavily with Mack designers as they penned the company's first buses for the 1930s, so much so that they were promoted as "street car buses". Mack's first new municipal transit bus entry was the massive 42-44 passenger Mack BT (1931-1934). It was the first city bus with an all-steel body, air brakes and tubular crossmembers.Power came from a Mack BK 525 cu.in. 120 horsepower 6-cylinder L-head gasoline engine.
