When the 455/8s on Southern we're modified a good 12-15 years back I'm intrigued to know why the interconnecting gangways at the front and rear of units were lopped off? After all the SWT never made this modification to their sets.
455s have guards? What routes do they work?
All the suburban SWR routes. Waterloo to Dorking, Guildford, Chessington, Woking, Hampton Court, Kingston loop and Hownslow loop.
