There’s this sign outside Made Tech’s London office for the London Low Line. A bit of searching online tells me it marks a walking route around some of the in use and abandoned railway arches. Next time I’m in the office I’m going to follow it.

A sign reads: Low Line. Follow beside the dramatic brick viaducts and discover some of london's industrial and commercial heritage dating back to the 19th century and the time of the rapid spread of railways between cities and across the country.
