Winchmore Hill railway station is in Station Road (which, before the arrival of the railway, was known as "Middle Lane"), Winchmore Hill in the London Borough of Enfield in North London, England, in Travelcard Zone 4. It is 14 km (8¾ miles) north of Moorgate on the Hertford Loop Line. The station, and all trains serving it are operated by First Capital Connect. Originally, upon opening in 1871, the station building was almost identical to that at neighbouring Palmers Green. However, in 1965 the northbound side of the building was demolished due to subsidence. In the 1970s the station boasted, on its southbound platform, a small newsagent and sweet shop, just beyond the base of the stairs down to the platform, but by 1980 this shop had been dismantled.
The service from the station runs to Moorgate on weekdays until about 10.00pm, and into London Kings Cross after 10.00pm Mondays to Fridays and all day on Saturdays and Sundays. Normally the service uses class 313EMUs, as these are the only units cleared to Moorgate.
