Pennsylvania Railroad Class E2b Electric Locomotives
The
Pennsylvania Railroad's class E2b was comprised of six experimental B-B electric locomotives built for the railroad by General Electric.

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

4 locomotives of the class E2b with the road numbers No. 4939–No. 4942 built by General Electric
2 locomotives of the class 
E3c with the road numbers No. 4995 and No. 4996 built by Baldwin, Lima & Westinghouse
2 locomotives of the class 
E3b the road numbers No. 4997 and No. 4998 built by Baldwin, Lima & Westinghouse

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

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.

The locomotives were scrapped in 1964.
