The station was located in New Mill End but took its name from the small hamlet of Chiltern Green about a mile away.

Adjacent to it was the GNR station of Luton Hoo also located in New Mill End.

The small hamlet of New Mill End is unique in having two railway stations (Chiltern Green and Luton Hoo) neither of which, after 1 December 1891, were named after the village they served.

Ironically, the branch line between Welwyn Garden City and Leighton Buzzard, which Luton Hoo was on, closed in 1965, meaning that New Mill End was no longer served by a local railway station.

The platform on the station building side partly survives but is overgrown and difficult to see when passing in a train.
