SR Class 6Pul
The Southern Railway (SR) gave the designations 6Pul, 6Cit and 6Pan to electric multiple units built to work the routes between London and Brighton, West Worthing and Eastbourne. None of these units survived long enough in British Rail ownership to be allocated a TOPS class number. The 6Pul units were designated 6Cor until 1935 (the Cor designation was later used for 4Cor units).
