Crowding, inconsiderate behaviour, air-con issues among top commuter concerns: PTC survey

It noted that train carriage temperatures are set at around 25°C and that the carriages are equipped with temperature sensors and thermostats that continuously monitor and maintain the temperature.

“However, commuters may perceive this differently depending on the time of day, elevated (versus) underground lines, passenger load and personal preferences,” the PTC said.

“The warmer climate in recent years may also have contributed to greater sensitivity to onboard temperatures for commuters during their journeys, even where cooling systems are operating as intended, especially during hotter periods of the year.”

Ensuring a comfortable commuting environment is an important focus for the public transport system, the council said.

For instance, the new North-South East-West Line trains feature higher cooling capacity and improved airflow are being progressively introduced, with the full replacement of older trains on this line targeted for completion in 2026, it added.

The PTC said it would explore ways to enhance travel comfort, potentially by optimising air-conditioning performance on older train fleets and reviewing maintenance practices where appropriate.
