The typical off-peak service is three trains per hour to London Euston, and three trains per hour to Watford Junction, calling at all stations. The trains to Watford Junction are northbound are accessed through a gateway and going down a flight of stairs, whereas the other platform is southbound and is directed towards London Euston. This accessed by crossing over a bridge and also going down a flight of stairs to reach the platform. On the northbound platform, there is a gate exit which now has an Oyster reader, so passengers can exit through the gate without having to climb the stairs. There are also oyster readers at the main entrance at the top of the bridge. During the Silverlink era, the gate was rarely opened - however in recent times, London Overground always leave the gate open.
The station was served by the Bakerloo line of the London Underground between 1917 and 1982 and it is planned that by 2025 when the Bakerloo line receives new rolling stock, London Overground services will be withdrawn and the Bakerloo line will be re-extended to Watford Junction.
Since the recent take over of this station from Silverlink to London Overground the ticket office opening hours have significantly improved and two ticket machines have been installed which now can update Oystercards and credit cards can be accepted.
