How to use the online timer

While you watch the departure board and work out which footbridge to take, a countdown of one hundred and twenty-one seconds can mark the usable part of a short train change. Keep walking at a steady pace rather than staring at the screen; the aim is to reach the next platform while still noticing signs, other passengers and any late alteration.

Crossing a busy station demands enough attention that a quiet alert may disappear beneath announcements, rolling luggage and idling trains. Set the volume before leaving the first platform, but do not rely on sound alone: keep the phone where its vibration can be felt, and glance at it only after stopping safely away from stairs, barriers and the platform edge.

As you move between platforms, treat the alert as the point when route-finding should end, not the instant your next task must begin. Leave the remaining moments for checking the train indicator, finding the correct carriage area and allowing for a platform alteration. If you arrive early, that reserve becomes calm waiting time; if the route takes longer, it shows which checks must happen while you continue moving.

Common questions

What if a platform alteration makes this short change take longer?

Follow the station signs and announcements rather than trying to beat the alert. Use the remaining journey time to confirm the platform and carriage position once you are clear of stairs or barriers.

What should I do if I reach the next platform before the countdown ends?

Keep the spare time for checking the departure display and whether the train divides en route. There is no need to restart the countdown when the transfer itself is complete.
