Mumbai's suburban rail system has seen an increase in air-conditioned (AC) local trains, with Central Railway (CR) converting 14 non-AC services and Western Railway (WR) converting 12 since May 1. However, commuters are experiencing persistent delays, with AC trains often running 10 to 15 minutes late. This situation creates a domino effect, impacting non-AC services and increasing overall wait times. Commuters like Varsha Dasani, who travels from Chhatrapati Shivaji Maharaj Terminus (CSMT) to Kalyan, express frustration over the reliability of AC services. Railway officials attribute delays to systemic issues and over-utilization of track capacity, which operates at 120% to 130% capacity. Additionally, overcrowding during peak hours causes further delays, as passengers block automatic doors. In response, authorities have deployed personnel to manage crowds and introduced queueing protocols to streamline boarding. Despite these measures, passengers report inadequate communication regarding service changes, often learning about substitutions only upon arriving at the platform. This lack of information, coupled with fare disparities between AC and non-AC services, adds to commuter dissatisfaction. AC services in Mumbai have gradually expanded since their introduction, yet challenges remain in ensuring reliable and timely transport for the city's commuters.
