The only intermediate station on the branch, Croxley lies between Watford, (the terminus) and Moor Park on the main line from Baker Street to Amersham. It is in Travelcard Zone 7. The southbound platform at Croxley is unusual in that it has no station starter signal.
The station is situated on the corner of Watford Road and Winton Drive in Croxley Green.
The Croxley Rail Link is a proposal to divert the Watford Branch east of Croxley to Watford Junction station. In 2005, plans were approved to link the line through Croxley which terminates at Watford station, via a deviation to the much more important station at Watford Junction. Intermediate stations would be built or rebuilt at Ascot Road tube station (near the old Croxley Green station), Watford West railway station and Watford High Street railway station.
