London Transport bus TD104 sits in Mill Hill East station forecourt (1962)
Route 240 was introduced in the 1930s between Edgware and Golders Green and replaced the former London General Omnibus Company Route 104.
Initially it was split into two sections, the Mill Hill Broadway station to Edgware section being operated by single-deck TDs and the Mill Hill to Golders Green section by double-deck RTs. This was because of the low railway bridge over Mill Hill Broadway which did not permit double-decker operation. The single-deck part was renumbered 240A and extended to Page Street, and then in 1951 was further extended to Mill Hill East station.
Route 240A is notable at this time as being the only London bus route that has ever accepted single tube tickets, between Mill Hill East, Mill Hill Broadway and Edgware in lieu of the planned extension of the Northern Line. A ticket for Mill Hill (The Hale) cost a little more than one to Mill Hill East, and enabled the passenger to retain their tube ticket for use on the 240A anywhere in the direction of Edgware.
