What is "horley"

Horley is a town in Surrey on the border of Surrey and West Sussex, England, south of the twin towns of Reigate and Redhill, and neighbouring Gatwick Airport and in turn Crawley. With fast links by train round-the-clock to London from Horley railway station, it qualifies as a commuter town and has a significant economy of its own, including business parks and a relatively long high street.
