Before 2 March 2024, 312 was from norwood junction to south croydon. But After 2 march 2024, the route was extended from South Croydon to Old Lodge Lane via Brighton Road (Purley) partially replacing route 455.
Pretty sure for 1.4 we could be getting an SL5 route or atleast the e200 branding as i've seen wheat spawning and driving it a few months ago on the 450.
I doubt Crystal Palace is coming since it’s not in the borough of Croydon potentially parts of purely way will be added for 119 289 312 455 and other route but Victoria line and 1.4 will probably be coming between sep-dec can’t wait
