Aintree railway station is a railway station in Aintree, Merseyside, England. It is on the Ormskirk branch of the Merseyrail network's Northern Line. Until 1968 it was known as Aintree Sefton Arms after a nearby public house. The station's design reflects the fact it is the closest station to Aintree Racecourse, where the annual Grand National horse race takes place.
