Southwark has been changed alot. I remember when Elephant and castle was full of Gemini 2 ,Gemini 1, Trident, ALX400, Scainca Omnicity, Plaxton President and Dennis Dart. TFL did change most of the routes. (P.S Ik Gemini 2 still run im talking about 2014/2015 before the first to ever use New Routemaster at Elephant and castle and it was 12)
