Full Journey on the Route 521 (SEe21 LJ66CFZ) Alexander Dennis E200EV BYD Go-Ahead London

Friday 28th April 2023 was the last day of the two iconic routes 507 and 521 which were sadly withdrawn so I decided to film these routes as these routes are quite interesting and this is my first time filming at the front on a single decker too! Quite a shame as these routes were useful to other people going from Waterloo to London Bridge and Victoria but TFL decided to be annoying. Anyways, here is 521 here being filmed and it was quite an interesting route as it went through the tunnel after Waterloo Bridge and won't go through there again. This route also serves Holborn, Chancery Lane, Holborn Circus, City Thameslink, St Paul's, Mansion House, Cannon Street, Monument and London Bridge. This route has unfortunately been withdrawn
