Extension was nt a problem , Earlier it used to arrive CBE at 7 : 10 AM , whereas LTT bound express will depart CBE at 5 : 00 AM itself. So the incoming rake will be taken to CBE pitlines and cleaned there . Now they changed the timings so that they can save one rake. So the incoming rake arrives at 7 :00 AM departs at 08:45 AM to LTT
