[[Pennsylvania Railroad]] class '''E2b''' comprised six experimental [[AAR wheel arrangement#B-B|B-B]] [[electric locomotive]]s built for the railroad by [[General Electric]]. 

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 [[Pennsylvania Railroad class E2c|E2c]] with the road numbers  #4995 and #4996 built by [[Baldwin Locomotive Works|Baldwin-Lima-Hamilton]] & [[Westinghouse Electric Corporation|Westinghouse]]
* 2 locomotives of the class [[Pennsylvania Railroad class E3b|E3b]] the road numbers  #4997 and #4998 built by [[Baldwin Locomotive Works|Baldwin-Lima-Hamilton]] & [[Westinghouse Electric Corporation|Westinghouse]]<ref name="staufer" />
GE built two demonstrators to show the [[Great Northern Railway (U.S.)|Great Northern Railway]]. These two were sold to the PRR in March 1953 and numbered {{Nowrap|#4943–#4944}}.<ref name="staufer">{{Harvnb|Staufer|Pennypacker|1962|pp=300–301}}</ref>

The class E2b locomotives were commonly used in three pairs.  Like most previous PRR electric locomotives, they were straight [[alternating current|AC]]-powered, and did not use [[rectifier]]s.  Because of this, they could [[Multiple-unit train control|work in multiple]] with existing PRR locomotives, and generally did so with class [[PRR P5|P5a]].<ref name="staufer" />

The locomotives were [[scrap]]ped in 1964.
