The Railways have cut by half to 60 days, the maximum period for advanced reservation of tickets with effect from May 1. This is an effort to by the Railway Ministry to rationalise the booking process to avoid huge cancellations. However, tickets booked up to April 30 under the 120-day reservation period would be valid, says a railway circular. Foreign tourists would continue to enjoy the facility of booking ticket 360 days in advance.The Railways have retained the lower time limit for reservation for certain trains such as the Taj Express and the Gomti Express. It was in March 2012 that the Railways increased the advance reservation period from 90 to 120 days,
