- Northfield Avenue, W13 9QU
Zone 3 Tube station on the Piccadilly Line.
One entrance, on Northfield Avenue. Covered bike parking is available just outside the station.
Although this station is on only one line, it has two westbound tracks and two eastbound. The reason for this is that there's a depot just beyond, and trains often terminate here; so one eastbound track will carry trains that have just come from the depot, and the other will carry trains that have come from stations further west. Similarly, one of the westbound tracks will be for trains terminating here, and the other for trains that carry on to Heathrow.
