The first, class BB1, were AC powered and served as prototypes. The second, class BB2, were DC powered and served in the New York Terminal district, specifically between Sunnyside Yard and New York Penn Station. The third, class BB3, was AC powered and built for the Long Island Rail Road's electrified freight operation on the Bay Ridge Branch. In 1934 a follow-up order of 14 locomotives were built as single unit class B1 for the expanding main line AC electrification system. In addition to these new units all previous BB classes were split into single units and the BB2 class were re-powered for AC operation as that system replaced the old 650 V DC system in the New York terminal. At this point all 42 units were re-classed as PRR B1.[1]
Most of the B1 fleet spent its time shuttling trains around Sunnyside Yard or between there and Penn Station. Other B1s were assigned to the Penn Coach Yard at Philadelphia
