One of the friend mentioned in one blog, he suggested SWR can make RSA between NCJ-SMVT (17236/17235) and 16526/16525 -SBC-CAPE Express
16526 SBC-CAPE reaches CAPE at 15.05 and the return 16525 CAPE-SBC departs only next day at 10.10 am. instead it can be RSA with NCJ-SMVT (17236) which depart at 19.15 a.m. on the same day
so...
more... the idling time of SBC-CAPE rake for nearly 19 hours at NCJ can avoided
Similarly SMVT-NCJ (via Tirunelveli, Madurai) reaches NCJ at 7.40 a.m. and it can RSA with CAPE-SBC depart at 10:10 am on the same day.
Things to be considered:
1.NCJ-SMVT (terminal has to change with SBC) again.
2. Both (NCJ-SMVT and CAPE-SBC) trains will be under SWR
3. Seshadri (SCR rake can be freed)
