Moor Park is a London Underground station in the Three Rivers district of Hertfordshire, predominantly serving those living in the Moor Park estate, but also in the neighbouring Eastbury and South Oxhey estates. The station is outside the Greater London boundary but is in both Zone 6 and Zone 7.
Moor Park station is located between Rickmansworth (towards Amersham), Croxley (towards Watford) and Northwood (towards central London) stations.
It lies between Sandy Lodge Golf Course and Moor Park. The station has four platforms, two for northbound trains (one for the Watford service and one for the Amersham/Chesham service) and two for southbound trains to Baker Street (one for the slow trains and one for fast - although southbound services vary in the morning peak).
Since 2011, fast and semi-fast services have only run during peak times with services to Aldgate from platform 2 during the morning peak, and services to Amersham and Chesham on platform 1 during the evening peak.
Every other time during the day, and all day at weekends, train services depart from platforms 3 and 4 providing all stations services to Baker Street or Aldgate to the south and Watford, Amersham or Chesham in the northbound direction.
Despite sharing the fast lines with the Amersham/Chesham trains, British Rail (Chiltern) (now Chiltern Railways) trains to Aylesbury/Marylebone ceased calling here in 1993.
