It is a large brick structure with a two-story central section featuring a cylindrical tower with a domed cap and one-story wings extending from each end along the railroad tracks.

It was designed by Baldwin and Pennington, and built in 1884 by the Baltimore and Ohio Railroad (B&O) across the tracks and a meadow from the Railroad's Oakland Hotel, which opened in 1876, to support the development of Oakland and Garrett County as a resort area.

[5] After performing freight service for years, the engine was sold in 1947 to the Mississippian Railway where it retained the Frisco number.

[5] Following several further changes in ownership,[5] the engine was acquired by the Oakland B&O Museum in 2018 where it was renumbered and relettered as the Baltimore & Ohio 476 as representative of a typical B&O locomotive.

[7] The tender mated with the locomotive was previously in operational service with the Arcade & Attica Railroad's Engine #18, and was acquired by the museum in 2018 in a swap.
