The Central Railway has rolled back nine rakes that used to run on direct current (DC), implying the consequent withdrawal of almost 117 services a day from the main line of its suburban local trains. Last week, the Central Railway successfully completed the conversion of traction from Mumbai CST to Thane from 1,500 volts Direct Current (DC) to 25,000 volts Alternating Current (AC). The conversion took place in the intervening night of June 7 and 8. Subsequently, nine rakes that used to run only on DC had been withdrawn from their daily service, claimed a senior Central Railway official.
“At present, these trains have been kept in the car-shed. A decision should ideally have been taken earlier on whether the 9 DC rakes could be retrofitted for use on the AC traction or whether they have to be discarded from services,” said the senior official.

Asked about the nine rakes, Narendra Patil, Chief Public Relations Officer of CR, said he could not comment on these nine but added that around 100 coaches that had completed their lifespan were being pulled out of service.
At present, the CR has a total of 121 rakes, of which the main line has 75 rakes. The rest run on the Harbour Line. The 75 includes the nine rakes now discarded. After the conversion, the Harbour Lines between CST and Panvel and the Thane-Vashi Trans-harbour lines are still running on DC traction. No decision has been taken yet on whether these nine rakes could be plied on Harbour line or Trans-harbour line, railway officials said.
Another senior Mumbai Railway Vikas Corporation (MRVC) official said retrofitting may be possible to operate the trains on AC traction.
Senior railway officials said some Siemens rakes could be passed on from the Western Railway to CR in order to increase services.
