Tube ponderings with Barry Heck

Our resident tube fancier dishes out daily thoughts on the London Underground.

London almost had a Brockley Hill tube station. Not in Brockley, as you’d expect, but north of Edgware on an extension of the Northern line. This station, along with Elstree South and Bushey Heath can only be visited if you have the ability to jump to alternative universes. In our universe, the extension was halted by the Second World War, and cancelled soon after. Some fragments of the project do survive, and I’ll share photos on a future update.
