This is a double ended double truck car that rides on two Brill 89E trucks with four General Electric 301B traction motors.

It passed to the Philadelphia Suburban Transportation Company as of December 19 1935 and to the Southeastern Pennsylvania Transportation Authority on January 29 1970 all with no change in car number. This car was retired and stored by SEPTA during 1980; it was sold to the Buckingham Valley Trolley Association that same year and to the Electric City Trolley Museum in 1999.
