The Frankfort and Cincinnati Model 55 Rail Car (also known as "The Cardinal" and, colloquially to residents along it route, as The Dinky) is a historic railcar on the National Register of Historic Places. The railcar currently resides at the Kentucky Railway Museum in New Haven, Nelson County, Kentucky. The Kentucky Railway Museum gained possession of The Cardinal in 1960. In 1997 it was one of a maximum of six known gas-powered motor rail cars left in the United States, and the only one in the Southeastern United States.
