SR/Paxman 500hp 0-6-0 Diesel-Mechanical

This locomotive was a Bulleid designed shunter also capable of branch line and trip working. Due to delays caused by economic conditions immediately after the Second World War the shunter, which was given the number 11001, was not completed until the Southern Railway had become part of British Railways [1].

By the time it entered service in 1950, British Railways was already busy creating a standard diesel shunter (the Class 08). 11001's gearing was, like many compromises, not perfectly suited for shunting duties or trip working although was the most powerful shunter built up until then [3]. It's working life was short and it was cut up in 1959.
