Father-and-son team Barney and John Gramling have a uniquely odd passion: the duo restore derelict locomotive steam engines, then travel them around the country - an endeavor they refer to as Have Engine, Will Travel. With the aid of local railroad associations and railway museums, they truck these incredible machines to different railroads, delighting railroad enthusiasts young and old. During the six-part HAVE STEAM ENGINE WILL TRAVEL series, the program captures the entertaining time on the road with Barney and John and their support team.
