bus and experienced the discomfort of Tamil Nadu’s punishing heat alongside everyday passengers. That first-hand encounter with overcrowded, sweltering conditions is said to have directly shaped his instruction to the Transport Department: future buses must come with AC built in. This isn’t the minister’s or CM’s first hands-on moment with the state fleet. Just days earlier, Vijay had flagged off 300 new government buses a mix of diesel and CNG vehicles worth over Rs 127 crore at the Chennai Secretariat, before surprising onlookers by hopping onto a public bus bound for Perambur, the constituency he represents. He greeted the driver and conductor, bought a ticket like any regular passenger, and even invited the conductor to sit with him during the ride.

From Diesel and CNG to a Fully AC Future

The all-AC mandate doesn’t stand alone it’s the latest layer in a wider transport modernisation drive. Earlier this month, during a review meeting on the department’s functioning, the Chief Minister had already directed officials to prioritise air-conditioned electric buses for future fleet additions and to examine the feasibility of rolling out a Bus Rapid Transit System with dedicated bus lanes. Taken together, the directives signal a clear trajectory: from diesel and CNG buses today, toward an electric, air-conditioned, technologically upgraded fleet in the years ahead.

The Scale of the Challenge

The numbers underline just how big an undertaking this is. Tamil Nadu’s state transport corporations currently operate 21,527 buses, carrying close to 2.05 crore (20.5 million) passengers every single day. Converting a fleet of this size to an all-AC standard will require sustained investment and a phased procurement strategy, since the shift applies to new purchases rather than an immediate retrofit of existing buses. The 300 buses inaugurated last week offer a glimpse of how this rollout is being distributed across the state. Of these, 65 went to the Chennai Metropolitan Transport Corporation, while the remaining vehicles were allocated across regional zones including Salem, Coimbatore, Madurai, Kumbakonam, Viluppuram, and Tirunelveli — to strengthen both urban and intercity connectivity.

Free Travel for Women and Smarter Ticketing

The AC announcement also dovetails with other commitments under review. The Chief Minister has been examining proposals to extend free bus travel for women across the state, one of the ruling party’s key poll promises. Alongside this, officials are working on introducing a smart card-based cashless ticketing system to replace the current method of fare collection, aiming to make travel faster and more transparent for daily commuters.

Tech-Enabled Terminals on the Horizon

Modernisation isn’t limited to the buses themselves. Plans are also underway to set up 24×7 information and control centres at major bus terminals, using GPS-enabled tracking to monitor departures, arrivals, and stops in real time. These centres are expected to be linked to the headquarters of each transport corporation, feeding into a proposed integrated command centre in Chennai — a move designed to give both officials and passengers better visibility into bus movements across the network.
