Seoul Subway Line 2 does not operate mild-air-conditioning cars: all cars use regular cooling. This guide explains the temperature target and how to check on-site information.
Line 2 car position
Line 2 has no mild-air-conditioning cars. All cars operate with regular cooling.
Check the train direction, platform car-position signs, exterior car number, and mild-cooling sticker in that order.
24°C regular cooling and 25°C mild cooling
The supplied standard gives a 24–27°C in-car range. Regular-cooling cars target 24°C and mild-cooling cars target 25°C; mild cooling is not air conditioning switched off.
Passenger density, door opening, sunlight, and airflow affect perceived temperature, so these are operating targets rather than live guarantees.
Public data and on-site signs
The public file is dated 10 February 2026. Use it for planning, but treat current platform and train labels as final.
If the sign differs from this guide, follow station staff and official guidance.
Why mild-cooling cars are provided
Passengers experience the same temperature differently. A choice within a train helps people who want stronger cooling and people who find a direct cold draft uncomfortable.
Since Line 2 has no separate mild-cooling car, choosing a place out of a direct draft and carrying a light layer can help.
Board safely
Wait at the planned position before the train arrives and do not force a move through the train as doors close.
If information is unclear, use the next stop to move safely or ask station staff.
