As the clock ticked over to midnight on December 31, ticketing system at the counters of suburban stations went kaput, inconveniencing Mumbaikars. Officials said the malfunction was caused during a software update to incorporate the hike in fares across the network, excluding suburban trains.

The malfunction was brief at most stations, said an official, adding that only a few stations, including Churchgate where the changes were not automatically adapted faced difficulty. These ticket counters were back on track by 5 am, once the update ended.
