It provides fast rail access to London Marylebone and to High Wycombe and Birmingham Snow Hill. Although its name has long been merely "Gerrards Cross", its original name was "Gerrards Cross for the Chalfonts". A single weekday service to London Paddington starts at the station, arriving in London at 1043 hrs (as of July 2008), running non-stop from West Ruislip. It traverses the rarely used former main line between Northolt Park Junction and Old Oak Common Junction, in many places reduced to a single track. This section is used more frequently by freight and waste trains, and also diversions during engineering works. There is an equivalent service from Paddington departing there at 1112 hrs, which runs non-stop to Gerrards Cross, but this train terminates some way to the north at Princes
