Chesapeake & Ohio Railway No. 1308 is an preserved articulated 2-6-6-2 "Mallet" type steam locomotive built by Baldwin Locomotive Works in 1949. It was the next to the last Class 1 mainline locomotive built by Baldwin, closing out more than 100 years of production, a total of more than 70,000 locomotives. Its other surviving sister locomotive, No. 1309, has been restored to operation at the Western Maryland Scenic Railroad in Cumberland, Maryland.
