SR Class 6Pul
 The Southern Railway (SR) gave the designations 6-PUL 6-CITY and 6-PAN 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 6-PUL units were designated 6-COR until 1935 (the COR designation was later used for 4-COR units).
