How is this train returning to CKP?? I think I have seen once the Engine is not reversed in TATA and a Diesel link is attached to the back after it reaches Tata from CKP and then pulled back to CKP so that it is ready with SRC E-Loco in the front to head towards HWH. The SRC E-Loco is reversed only once at CKP after it arrives from HWH before leaving for TATA.
If this is the case then everyday from where the Diesel locos are coming to CKP and how they returns to TATA??
