First N18 Bus: Start of Service
The first N18 of the day from every stop on the route
The N18 is a night bus, so its "first bus" is the first departure of the night, leaving Harrow Weald Bus Garage at 23:15 (Daily). The tables below show the scheduled first N18 departure from every stop, in each direction, for each day of the week. Stop names link to the full N18 timetable with every departure of the day.
To Whitehall / Trafalgar Square
To Long Elmes
Times are TfL's scheduled first departures from each stop in the given direction; the final stop's time is an arrival. Columns cover the days shown in their heading, and the highlighted column is today. On busy mornings buses can run a few minutes later than scheduled, so allow a small buffer if the first bus matters for a connection.
