Croxley is a London Underground station located on Watford Road (A412) in Croxley Green, Rickmansworth, Hertfordshire, on the Watford branch of the Metropolitan line.

There had been shuttles running to and from Rickmansworth stations regularly but was withdrawn in January 1960, later reinstated in 1987 but only one in early morning and late evenings each way.

The shuttles to Rickmansworth were later extended to Amersham following the introduction of the longer S8 Stock trains.

The diversion would require the construction of a viaduct over the Grand Union Canal, River Gade and the A412.

On 25 January 2017, the Watford Observer newspaper published an update on the Croxley Rail Link confirming work had stopped as there was an ongoing funding issue.
