On Monday, commuters travelling on the Central Railway (CR) and Western Railway (WR) experienced considerable delays and cancellations. When WR discovered damage to a cable at 2 a.m. when micotunnelling a cross-culvert at Borivali station, the company had to cancel 90 services. A malfunction in the recently installed signalling system at CSMT and a speed limit at Thane for the enlargement of two platforms to relieve crowding caused CR to cancel 80 trips in the meantime. The trouble was reported to have begun with the first morning trains on both WR and CR, around 4 a.m. While the WR issue had been resolved by 1.30 pm, it was stated that CR would require four to five days to fix the signalling system. According to CR?s chief public relations officer, Swapnil Nila, he mentioned that in new systems, glitches do happen, and their team is actively working on rectifying these issues. He further elaborated that for a major yard such as CSMT, the system is extensive and requires time to stabilise and correct any faults, which cannot be identified beforehand as they occur during actual train movement. Additionally, CR?s divisional railway manager (Mumbai), Rajneesh Goyal, added that a signalling cable at CSMT had been cut, leading to further delays. It was noted that CR had been facing problems since May 31 following a 63-hour block for infrastructure upgrade, which included the widening of Thane?s platforms 5 and 6 and the switch to automatic signalling to commission a 24-coach platform at CSMT. A CR official mentioned that the problem had occurred on fast tracks catering to long-distance trains, with signals frequently going off and on. Consequently, fast corridor services had to be diverted to slow lines, impacting all services. However, it was stated that there was not much of a problem on the harbour line. Moreover, speed restrictions were imposed between Kopar and Diva due to the widening work at Thane, resulting in a 1.5-degree curvature that necessitated slower train speeds. A cable problem was discovered in Borivali at two in the morning, the WR spokeswoman continued, resulting in a signal breakdown. Suburban trains were thus unable to run from Borivali station's platforms 1 and 2. At 12:05 p.m., train operations began from platform 1, and at 1:30 p.m., from platform 2. WR provided 35 unique services. There was severe congestion at the Borivali railway station, Kurar, and Rashtriya Udyan Metro stations due to the Western Railway delay. Sanjay Mukherjee, the metropolitan commissioner, responded by ordering the installation of more services to ease the congestion. During peak hours, 21 train units typically run. A total of 24 train sets were placed into service on Metro 2A and 7 (Gundavli-Dahisar-Andheri West) on Monday owing to issues on WR.
