1920s Tech Finally Cleaned Out in London Underground Refresh

By Gary Cutlack on at

A quite amazingly brave and tireless little signal box that should be the star of a series of books has finally retired, with the piece of kit inside Edgware Road station at last being allowed to have a rest and a sit down in a museum.

First installed in 1926, the Edgware Road station box organised trains on the Circle and Hammersmith & City lines. It's such a brave little collection of wires and levers that it's been designated an item of national historic interest by the Railway Heritage Designation Board, meaning that hundreds of men with an interest in transport will be looking at it from now on.

It was past its use-by date though. The new digital replacement should allow trains to travel closer to each other, with the aim being to increase the number of trains running on the two lines by 33 per cent by the start of the next decade. London Underground heritage manager Mike Ashworth said: "This unique signalling cabin harks back to the earliest days of London's transport network, being originally built and used by the Metropolitan Railway in 1926. It is a testament to its pioneering design and robustness that it is still in use today."

But now it's in the bin to be replaced by a sensor and an app. [TfL via E&T]
