Whoa, what? Which website? Everything in indianrail.gov.in and indianrailways.gov.in is developed by CRIS. The ticket booking in irctc.co.in is developed with IRCTC itself on top of a BroadVision product. IRCTC links with the PRS of CRIS.

TCS is not at all related to IRCTC online ticketing operations.

Whoa, the huge amount of misinformation in this item's comments is staggering.
