	It was a late spring evening when the family gathered in Clifton Forge to wait for the train to Cincinnati. Everyone was pretty excited as a train trip on the C&O was always a great experience.

The Chesapeake and Ohio Greenbrier was a class of 12 4-8-4 "Greenbrier" type steam locomotives built by the Lima Locomotive Works between 1935 and 1948 and operated by the C&O. Like a handful of railroads, the C&O didn't name their 4-8-4s "Northerns", and instead went with the name "Greenbrier" after the Greenbrier Hotel in White Sulphur Springs, West Virginia, a major resort on the C&O mainline.

They were built with the primary purpose of hauling long, heavy, high speed 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 614 survives and is on display.
