Career Operators Pennsylvania Railroad Class E2b Numbers 4939–4944 Scrapped 1964

In 1952 the Pennsylvania Railroad took delivery of eight experimental locomotives:

• 4 locomotives of the class E2b with the road numbers #4939–#4942 built by General Electric
• 2 locomotives of the class E3c with the road numbers #4995 and #4996 built by Baldwin-Lima-Hamilton & Westinghouse
• 2 locomotives of the class E3b the road numbers #4997 and #4998 built by Baldwin-Lima-Hamilton & Westinghouse[1]

GE built two demonstrators to show the Great Northern Railway. These two were sold to the PRR in March 1953 and numbered #4943–#4944.[1]

The class E2b locomotives were commonly used in three pairs. Like most previous PRR electric locomotives, they were straight AC-powered, and did not use rectifiers. Because of this, they could work in multiple with existing PRR locomotives, and generally did so with class P5a.[1]

The locomotives were scrapped in 1964.
