SR superstar at Chennai Egmore station. As the train halted at MS, I ran to take the loco pic as this is the only station where you can cover the entire rake & still board the coach. After this the train halts for a very limited number of stations that too for 10 mins. When I reached the end, there was no loco attached to it. The ED monster was decoupled and went to take 2 HCPV coaches and then coupled it at the front end. Tight security around HCPV coaches while GS pax enjoyed the coupling show.
