MUMBAI: Central Railway (CR) services are expected to operate according to schedule for the first time since the implementation of a new signalling system on June 1. Authorities have been granted permission to modify the software to facilitate timely train arrivals and departures at Chhatrapati Shivaji Maharaj Terminus (CSMT).
CR had sought approval from the Railway Board to address significant delays that emerged following the commissioning of the Electronic Interlocking (EI) system at CSMT. The EI system, a cutting-edge signalling technology, enhances safety and operational efficiency by replacing the older Route Relay Interlocking systems with computerised controls. The delays in train services at CSMT were primarily attributed to a 2021 circular issued by the Railway Board’s signal and telecom directorate. This directive mandated that trains travel an additional 250 metres before the next train could proceed. Previously, a train could move once the preceding train had cleared just 70 metres from the crossover point. This additional requirement, combined with the existing 70 metres, added approximately 90 seconds to the schedule, causing delays for about 50 long-distance and 40 local trains daily at CSMT.
The increased safety measure, coupled with the existing speed limit of 15 km/hr at crossovers, resulted in bunching and cascading delays. The impact was felt across local train services, as both long-distance and suburban trains share the same tracks. CR authorities had requested a relaxation of these norms specifically for CSMT, highlighting its status as a terminating station with low speeds and infrequent accident occurrences. Following the Railway Board’s approval, CR has adjusted the software to ensure that clearance is given to the following train as soon as the current train crosses the 70-metre mark, rather than the previously mandated 250 metres.
A CR official confirmed, “After the Railway Board’s approval, we have made changes in the software so that clearance to the following train will be given as soon as the existing train crosses the 70 metres instead of the previous 250 metres.” This adjustment is expected to significantly reduce delays.
However, despite this improvement, delays may still occur due to other factors such as signal issues, Overhead Equipment (OHE) failures, track-related problems, or the late arrival of long-distance trains into suburban territory. To maintain punctuality, CR had been compelled to cancel at least a dozen trains until Sunday. With these new measures in place, passengers can expect a more reliable and timely service, easing the daily commute for thousands of travellers.
