Snow sweeper #1 was delivered to the Beaver Valley Traction Company, headquartered in New Brighton, Pennsylvania. Beaver Valley Traction and Pittsburgh Railways shared the same parent company. It was delivered at the same time as six similar cars purchased by Pittsburgh Railways for use in Pittsburgh. The car came to Pittsburgh after the Beaver Valley line closed down in the 1930s. It is the only piece of surviving equipment from that company.
The basic appearance of the snow sweeper did not change appreciably in the two decades separating the manufacture of M37 and this car. But there were significant structural improvements to this later model, such as the steel frame that supports the body.
