Metropolitan Transport Corporation (MTC) is proving inadequate for the city’s sweltering climate. These non-AC buses, designed with the same shell as their air-conditioned counterparts, are facing severe ventilation problems, leaving passengers to endure uncomfortable journeys.
The primary concern revolves around the bus design, which, while suitable for cities with moderate climates such as Bengaluru, falls short in Chennai’s heat. With temperatures frequently soaring above 35°C, the buses’ ventilation system, particularly in the last two rows where small windows offer minimal air circulation, has been found lacking. This issue becomes exacerbated during peak hours when the buses are crowded with standing passengers, further impeding air flow. To alleviate the discomfort, bus crews have resorted to keeping the roof hatches open—an emergency measure typically employed only in critical situations such as bus overturns. This temporary fix highlights the inadequacy of the buses’ current ventilation system. In response to growing concerns, MTC has acknowledged the issue and has promised to address it. A representative from MTC noted on social media that the corporation is reviewing the situation to find a viable solution.
Experts suggest practical improvements that could enhance passenger comfort without incurring high costs. A mechanical design engineer from the TNSTC Enthusiasts group, which collaborates on bus design improvements, recommended the installation of centralised blowers. These blowers, similar to those used in the newly designed suburban train coaches, could significantly improve air circulation. The Delhi Transport Corporation (DTC) has successfully implemented such solutions to combat summer heat.
Alternatively, installing small fans in each seat row could offer a more affordable and effective solution to the problem. This approach would ensure better airflow and a more comfortable experience for passengers navigating Chennai’s challenging climate. As the city grapples with the heat, these suggestions could provide much-needed relief and improve the overall quality of public transport for Chennai’s residents.
