Class 307 EMU's stored withdrawn in Burton Dassett Yard at MOD Kineton. 1993.
Introduced in 1956 as 1500v DC suburban stock for the London Liverpool Street to Southend Victoria route the class 307s were all converted to 25kv AC in 1960-61 when the route was upgraded to AC electrification standards. Mass withdrawals started in 1990 as they were being replaced by newer class 321 units on the Southend Victoria route out of Liverpool Street and by June 1990 their days on the London commuter run had ended with all 32 sets withdrawn. Four units were reprieved and hastily refurbished for use on the newly electrified Doncaster to Leeds local services but only as a stop gap while WYPTE awaited delivery of a small fleet of class 321/9's. Of the four sets seen here stored in Burton Dassett Yard at MOD Kineton 307 105 on the right is in WYPTE livery while the other sets; 307 129, 125 and 131 are in BR blue & grey or NSE red, white and blue livery., In 1993 the Engineering Development Unit at Derby Research Centre converted two class 307 DTSO (Driving Trailer Second Open) vehicles to PCV's (Propelling Control Vehicles) the two prototypes proved very successful and a further 43 were converted by Hunslet-Barclay, Caledonia Works, Kilmarnock in 1994-96. Their use being on parcels and mail trains where propelling moves could be controlled by a driver riding in the PCV cab operating a system known as PACS (Propelling Advisory Control System). Of the 64 class 307 DTSO vehicles 45 became PCV vans with seating and windows removed and roller shutter doors fitted and renumbered as NPCCS vehicles 94300 to 94345 TOPS Code NAA. The unusable intermediate motor coaches and trailer cars mostly went for scrap.
