For train wrecks and certain maintenance work, railways always had set of equipment known as the "Auxiliary" which usually consisted of a crane, a tender (for steam powered cranes) and boom car. The Society obtained its Central Vermont Auxiliary in 1967.
Former Central Vermont Railway steam crane, 4251, was built by the Industrial Works (later Industrial Brownhoist) in 1919.
The 50-ton crane was acquired by the Society in 1967 along with the auxiliary equipment needed to support the crane's operation: the locomotive tender and a boom car. Number 4251 was received in operating condition and over the years the Society has fired the crane up and operated it during special events at the Canada Science and Technology Museum in Ottawa where the crane resides.
The Society continues to maintain 4251 in working order and hopes to continue operating it in the years to come. Occasionally the crane is put to work lifting other Society equipment.
