LAHORE (APP) - The delay of trains has become a norm which speaks of the inefficiency of the railway administration. Pakistan Railways sources said here on Wednesday that almost all mail and passengers trains were arriving and departing late from Lahore and other cities across the country. This uncertain schedule of trains forced the passengers to wait for hours at railway stations as there was no mean of transport for some areas in the country. The cancellation of several trains because of shortage of locomotives have also added the misery of the railway commuters. Trains from Quetta, Karachi to Peshawer are coming late by two to ten hours. Operation of several passenger trains for branch lines have to be suspended due to the unavailability of locomotives.
