GP35/GP38 Rebuild ProgramIn the early 1980's, Conrail had thousands of second-generation locomotives sitting in storage across the system. Still looking for ways to save money and turn a profit, Conrail wanted to test the feasibility of a GP35 rebuilding program. They selected Conrail GP35 2363, which was a former PRR/PC unit built in April 1965, as the test unit. The GP35 had been retired on February 2, 1981 and had been sitting in storage. Conrail hauled it into its Juniata locomotive shops and got to work rebuilding it into an unusual looking GP38. On November 29, 1984, Conrail released the new locomotive as GP38 CR 7635.
Conrail downgraded the GP35's horsepower from 2,200hp to the standard 2,000hp for GP38's. Conrail also rebuilt the old GP35 prime mover with EMD 645 power assemblies and de-turbocharged it as well, adding two additional exhaust stacks. They added a paper filter ahead of the dynamic brake blister but deactivated and blanked off the old dynamic blister to make more room inside the long hood. Conrail also replaced the original GP35 class lights with the FRA-approved 'bug-eyes' lights normally found on Conrail's SD40-2R's, SD50's, and SD60 series locomotives.
Since the rebuild program was a bust, CR 7635 became the only rebuilt GP35/GP38 on the system. For a while it operated on Conrail's Midwest lines until it wound up working on Conrail's East Coast lines. On June 11, 1997, Conrail officially retired the unit from service. Ironically, CR 7635 served nearly as long as a GP38 as it did as a GP35.
In 1997, Conrail sold 7635 to the Quebec Gatineau Railroad (Chemins de fer Québec-Gatineau), which operated over former Canadian Pacific trackage, and is part of the railroad operated by Genesee & Wyoming Canada. QGRY reclassified the unit as GP35m and renumbered it as QGRY 2006. In 2017, the unit was spotted with the designation GP38-2 on its cab. QGRY 2006 is still operating as of this writing in 2018. 
Comprehensive EMD GP38 Roster
The roster below is comprehensive for Conrail's GP38 between 1976 and 1999. It contains all predecessor units of the locomotive class that Conrail inherited. If numbers are missing from the roster, Conrail intentionally left them open. It does not contain retirement dates and dispositions due to their complex nature.
