There are two contacts. The main and the auxiliary. The auxiliary is housed in a vacuum enclosure. It picks up and connects a split second before the main contact. This done to avoid arching at the main contact.

Looks like a typical "AB" switch.

I was at the same location on PF. Later the train departed only after RPF shooed away the crowd as it was blocking LP's view ahead thro' bay windows.

It is a copy of the WG loco. The front is actually very well copied.

@ Karthik..

Railway track is a flexible (floating) structure not like a building which is attached rigidly to the ground. So in a track the stresses developing due to expansion/contraction are absorbed by sleepers (rather a set of sleepers) themselves and transferred to subgrade below. Its because of this feature only that LWRs and CWRs has been made possible..
