Atlas N scale ALCO C-628 diesel locomotive, catalog #54008, decorated for the Pennsylvania Railroad as road number 6305. It’s in Brunswick green with yellow numbers and red-and-white keystone heralds, and it comes in its original Atlas jewel case with the foam insert.

The real C-628 was a six-axle, 2,750 hp heavy-haul freight unit in ALCO’s Century series. The PRR was one of the larger buyers. This early-production Atlas model is the standard DC version.
