Hey Deepak, first off, chill out with the attitude... You ain't nobody to be demanding anything from me or anyone else... next time, try asking without the attitude. If they use RSA, they won't need as many rakes to maintain the service. Maybe not exactly 4, but definitely less than the 8 rakes used on both trains. The fact that they now arrive and depart from the same station at both ends helps reduce the shunting of empty rakes around, like from MMCT to BDTS and vice versa. For example, when a rake of 12903 arrives at ASR at 2340 hrs, it can depart as 12926 at 0735 hrs, so it only has about 8 hours of idle time. Similarly, when a rake of 12926 arrives at MMCT at 1455 hrs, it can depart as 12903 at 1845 hrs, so it only has about 4 hours of idle time. A rake of 12904 arriving at MMCT at 2335 hrs can depart at 1125 hrs the next day as 12925, so it has about 12 hours of idle time. To be honest, I completely forgot about the changed timings of 12903/04. Under the old time table, when 12925 arrived at ASR at 1920 hrs, it could have departed as 12904 at 2125 hrs, so it only had about 2 hours of idle time. So it's doable, but it needs more planning with rake management and scheduled maintenance procedures.
