Chesapeake and Ohio 1642 was a class "H-8" 2-6-6-6 steam locomotive built by the Lima Locomotive Works at Lima, Ohio for the Chesapeake and Ohio Railway.

On June 9, 1953, No. 1642 suffered a crown sheet failure and subsequent boiler explosion due to a prolonged low water condition at Hinton, WV. The crew members were killed. The locomotive was not rebuilt, as the class was undergoing retirement by then.[2]
