Pennsylvania Railroad class E2b comprised six experimental B-B electric locomotives built for the railroad by General Electric.

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

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.
