	References:

The Chesapeake and Ohio Greenbrier was a class of twelve 4-8-4 steam locomotives built by the Lima Locomotive Works between 1935 and 1948 and operated by the Chesapeake and Ohio Railway (C&O). The C&O did not name their 4-8-4s "Northerns", and instead chosen the name "Greenbrier" after the Greenbrier Hotel in White Sulphur Springs, West Virginia, a major destination on the C&O mainline.

They were built with the primary purpose of hauling heavy express passenger trains for the C&O Railway, such as the George Washington and the Fast Flying Virginian. All retired by the mid 1950s, only No. 614 is preserved, and it is undergoing restoration to operating condition.
