Check inside to view photos of the distinctive ex-PRR ore jennies. The PRR designed and built these cars to haul ore from docks in Philadelphia and Cleveland to steel mills in Pennsylvania, Ohio, and West Virginia.
The original class of ore jennies built by the PRR, these cars were designed to carry heavy grades of iron ore pellets. 1000 G38s were built in 1960 by the Sam Rea Shops. As time went on, ores had a lower iron content and were therefore lighter, which led to the development of the G39s. Despite their lower capacity, the G38s could still be found in service until the mid to late 1990s on some routes. The vast majority of the G38s were retrofitted with 77-ton trucks and re-classed G38Bs.
The G38B class consists of G38's retrofitted with 77-ton trucks.
Conrail's G39 class was designed to carry lighter grades of iron ore. Sam Rea Shops built 1000 in 1961.
Conrail's G39A class was built in 1964 by the Sam Rea Shops, numbering 1000 cars. 110 of these cars were given the experimental foam insulation on the outside to try to keep the taconite pellets from freezing into a solid chunk
Conrail's G39B class originated by equipping older G39 class cars with more modern trucks.
