Pennsylvania Railroad class E3b was an experimental electric locomotive supplied by Westinghouse Electric & Manufacturing Co. [1] The locomotive was of the two unit design, with each unit having a B-B-B or Bo-Bo-Bo wheel arrangement. [1]

Jan 14, 2021 · The last word in PRR electric locomotives was a road-switcher-type freight hauler that used the A.C.-to-D.C. ignitron-rectifier technology pioneered by the E3b and E3c. GE built the final 6 E44 units with silicon-diode rectifiers, raising their output to 5,000 h.p. and resulting in an “E44a” designation; 22 others were later so modified ...

Shown here (L to R) are PRR engines #4995 and #4730. #4995 is an E-3B (B-B-B) electric built by Baldwin-Westinghouse during June of 1951, rated at 3,000 horsepower, and retired in June of 1965. #4730 is a P-5A (2-C-2) built by Baldwin-Westinghouse in December of 1932, rated at 3,750 horsepower, and retired in November of 1964.

Pennsylvania Railroad class E3b was an experimental electric locomotive supplied by Westinghouse Electric & Manufacturing Co. The locomotive was of the two unit design, with each unit having a B-B-B (AAR) or Bo-Bo-Bo (UIC) wheel arrangement.

Class B comprised the 0-6-0 type, the most popular arrangement for switcher locomotives on the PRR. Class C was assigned to the 0-8-0 type. These were very common on other railroads, but the PRR was not keen on them and only built a few. This was partly because the PRR used 2-8-0 "Consolidation" types for similar service.

WHEN two ignitron rectifier freight locomotives (class E2C and E3B) were first put into service on the Pennsylvania Railroad (PRR) approximately 2 years ago, the event could well have been taken as marking the golden jubilee of main-line electrification in this country.

In Oct 2013 I began a post re these 3 PRR electrics. It is unfortunately, now closed. So in order to gauge if enthusiasm remains for these engines, I am reopening the issue once again.

Pennsylvania Railroad class E3b was an experimental electric locomotive supplied by Westinghouse Electric & Manufacturing Co. [1] The locomotive was of the two unit design, with each unit having a B-B-B or Bo-Bo-Bo wheel arrangement. [1]

AC current fed via transformer tap changers to AC traction motors. 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.
