Set the timer to 79 seconds

How to use the online timer

Waiting beside the carriage door for a short train change can make seventy-nine seconds feel surprisingly long. The countdown marks the window for crossing the platform or taking the footbridge, while you stay still until it ends rather than repeatedly checking the departure board. When the signal sounds, the pause is over and the move towards the connecting train begins.

During that wait, station announcements may be playing through headphones without being obvious to their owner. The countdown sound can disappear into the same earpieces, especially after a podcast or music has been paused. Keeping the phone visible provides a silent cue as the remaining time falls, which is useful on a busy British station where an announcement, a closing door or a platform alteration may otherwise compete for attention.

Before crossing to the next platform, the useful interval comes from the route rather than from an arbitrary setting. A level walk across a small station needs less time than stairs, a footbridge or a lift, while luggage and crowds add uncertainty. If the connection regularly takes longer, the practical adjustment is to start the countdown earlier; if it ends with plenty of waiting left, a shorter interval will match that particular interchange more closely.
