Harrow & Wealdstone - for Harrow see Harrow-on-the-Hill. Wealdstone was Weald Stone in 1754 and the name probably derives from the Old English weald, 'a forest', indicating that the land here was once covered by the heavy Middlesex woodlands, and a 'boundary stone'. A 'stone', three feet tall, still stands outside the 'Wealdstone Inn' but it is doubtful if this is the original one. We may assume that Wealdstone means 'the boundary stone in the forest'. The growth of this place dates from the opening of the London & Birmingham Railway.
The station was opened by the London & Birmingham Railway as HARROW on 20 July 1837. It was renamed HARROW & WEALDSTONE on 1 May 1897 and first used by Underground trains on 16 April 1917.
