Depends which 'link' you're in... But as a new starter you'll be in a lower link, you'll most likely be doing;
Waterloo- Waterloo (Via Kingston)
Waterloo- Waterloo (Via Hounslow)
Waterloo- Hampton Court
Waterloo- Chessington South
Waterloo- Dorking
Waterloo- Guildford (Via Epsom)
Waterloo- Guildford (Via Chobham)
Waterloo- Guildford (Via Woking)
Waterloo- Woking
Waterloo- Shepperton
Waterloo- Weybridge (Via Addlestone)
Waterloo- Windsor & Eton Riverside
Waterloo- Reading
I'm pretty sure that's it...
Best of luck with the DMI! I'm towards the end of my trainee drivers rules course (gonna be based at Wimbledon), I was a guard at Strawberry Hill for 2 years. One of the best decisions I've ever made was to join the railway.
Waterloo to Reading isn’t in the “starter” links
