EMD FP7
PRR #9855
The "PRR EMD FP7" refers to a specific model of a dual-service diesel locomotive, the
EMD FP7, as operated by the Pennsylvania Railroad (PRR) and produced between June 1949
and December 1953. These locomotives were built for both passenger and freight
service. Key details - Locomotive type: EMD FP7, a 1,500 horsepower (1,100 kW)
dual-service locomotive. Manufacturer: General Motors' Electro-Motive Division
(EMD). Service: Designed for both passenger and freight hauling, featuring a larger car
body than the standard F7 to house a steam generator for passenger service. Specific units
owned and operated by the PRR, had road numbers from 9832A to 9871A for the A units and
9832B to 9858B for the B units. Paint schemes: The first units were painted in the
passenger scheme of Tuscan Red with five Buff stripes, while the rest were painted in the standard freight scheme.
Additional details - The Pennsylvania Railroad (PRR) EMD FP7 paint schemes varied based on the
delivery date and service type, but the two main schemes were Dark Green Locomotive Enamel (DGLE) with five
gold stripes for freight and early passenger units, and Tuscan Red with five buff stripes for newer or
repainted passenger units after August 11, 1952. A single buff stripe was used for later freight-service FP7s.
The Dark Green Locomotive Enamel (DGLE), also called "Brunswick Green," with five gold leaf stripes was
the standard passenger paint scheme before August 11, 1952. Some FP7s delivered after this date but before
the full switch to Tuscan Red were painted in the DGLE scheme, particularly the "single-stripe" version used
for freight service. The Tuscan Red scheme with five buff (dark yellow) stripes was introduced on
August 11, 1952, this became the new passenger scheme for new deliveries and repaints. The design and placement
of the stripes, as well as the PRR keystone marking on the front, changed between 1952 and 1955. After
November 16, 1955, the Tuscan Red scheme was modified to include a single broad stripe with a shadow keystone.
