Differently-abled persons can book online portal irctc.co.in
Currently, the Railways provides a quota of two sleeper class tickets per train for the differently-abled, which could be booked only physically from any booking window. The online option has gone live from Thursday. Now, passengers only need to give details of the ‘Handicap Card’ number while booking the e-ticket, which will be verified by the TTE after boarding the train. The type of concession – ‘Escort’ or ‘Handicap’ can also be mentioned. Earlier, disabled persons could not avail concession while booking e-tickets. (newindianexpress.com)
