DCC Ready. 21-pin decoder required for DCC operation.
The Dukedog sobriquet comes from Mr Colletts' cost-effective solution, a 'new' locomotive built using the sturdy double-frame chassis from a Bulldog class 4-4-0 locomotive combined with the lighter weight boiler and cab from a Duke class engine. The result was quite out of place in the Swindon locomotive family, outside frames and boiler domes were features which had been discarded under Churchwards' management, but the dome did give the locomotives a quite distinguished look. Initially the engines were intended to carry the names of Earls, however the gentlemen concerned quickly took exception to their titles being carried by locomotives of such antiquated appearance and the class remained unnamed.
