A fast exit is not always the fastest way outside

Fast-exit information identifies doors close to a platform facility such as stairs, escalators, or elevators. The best position can differ depending on whether you are transferring, heading for an exit, or using an elevator.

Choose your destination and the facility you need first, then check the car and door in DoTheG. Compare it with floor or screen-door markings before the train arrives.

How to read the car and door position

A position such as 5-2 normally means door 2 of car 5. The same station can have a different position by line and travel direction, so do not rely on the number alone.

In DoTheG, confirm the line and direction first, then choose the facility and car-door position. Platform signs are the final reference because train formations and local markings can vary.

Check three things before you board

Confirm the destination station and line, the train direction, and the facility you actually need. With luggage, an elevator may be more useful than the nearest stairs; for a transfer, follow the transfer signs after getting off.

Construction, inspections, and platform changes can affect the real route. Use fast-exit information for planning, then follow station signs and staff guidance on site.
