The BMC has installed an advanced ventilation system near Chhatrapati Shivaji Maharaj Terminus (CST) subway to improve airflow and regulate temperature. This system will help to enhance ventilation and also lower the temperature, creating a more comfortable environment for commuters. Moreover, a centralised mech.sm will efficiently expel hot air, ensuring the subway remains cool and fresh, even during peak hours.
Covering approximately 3,000 sq.m, the subway outside CST serves as a crucial underground corridor, connecting Central and Harbour line commuters to prominent destinations in Fort, such as DN Road and Mahapalika Marg. Since its inauguration in 1999, the subway has drawn criticism for overcrowding, poor lighting, inadequate ventilation, and unhygienic conditions. The pedestrian movement has also been hindered by illegal hawking and unauthorised shop extensions. Some of the shops in the subway had set up air conditioners which cool their small space, but add to the heat load in the subway.

To improve airflow in this heavily used subway, the ‘A’ ward office under whose jurisdiction the subway falls, has recently upgraded the ventilation system with nine jet fans and two high-capacity fans. “These fans efficiently draw fresh air from entry points and expel stagnant air, ensuring continuous ventilation. Inspired by tunnel ventilation technology, this system ensures the subway remains well-ventilated and comfortable for users at all times. The system also prioritises safety in case of fire. In an emergency, the central fans will activate at double speed to quickly clear smoke and improve visibility, enhancing commuter safety during such incidents,” said a civic official. According to BMC, the CST subway houses 51 shops.
