I’m at St Marks Gate/Cadogan Terrace. The Greenway - a scenic walk down a Victorian super-sewer starts just a few meters away, as you can smell in the breeze. This is also the site of the death of the first person to be murdered on a railway train.

A blue plaque at 129 Cadogan Terrace commemorates Thomas Briggs Esq. of Clapton as the first person to be murdered on a railway train, describing his violent assault on a North London railway train on 9th July 1864 and subsequent death.
