THE number of trains operating on the Beijing - Shanghai high-speed line has been cut today from 88 per direction to 66 in the wake of the recall, which starts today on a step by step basis, of 54 CRH380BL trains by China CNR for safety checks. The Ministry of Railways has redeployed 21 CRH380A trains manufactured by CSR from other lines, but this is not sufficient to maintain the timetable.
