"Passenger Reservation System (PRS) centre at a location is established as per the extant policy guidelines and subject to technical feasibility and commercial viability. Under the policy guidelines, one PRS centre was commissioned and is presently functional at the New Bus Stand complex in Perambalur town since January 2005. This is considered adequate for the present volume of booking," Vaishnaw said in a written statement on Wednesday.

Vaishnaw said both reserved and unreserved tickets can be booked online, which is an easier and convenient way to get the tickets from anywhere and anytime.

"Railways has recently launched the RailOne App. This App enables passengers to book reserved as well as unreserved tickets on a mobile phone. This, in effect, brings the PRS facility to the passenger's palm," Vaishnaw said.

"Proposals/representations, both formal and informal, for the provision of PRS centre at a location are received from Members of Parliament, elected representatives, organisations/rail users, etc., at various levels including Railway Board, Zonal Railways, Divisional Office etc. As receipt of such proposals/representations is a continuous and dynamic process, centralized compendium of such requests is not maintained," the railway minister said in response to a Nehru's question on the details of the number of representations received from the public and elected officials demanding the establishment of a PRS centre in Perambalur in the last five years.
