I'm confused. I was on the 18.03 Charing Cross - Hastings today and all 12 carriages continued past Tunbridge Wells (where the back four normally detach) to Hastings. It was my understanding that this couldnt happen due to power supply limitations south of Tunbride Wells and that these limitations were the main reason that Thameslink wont go south of Tunbridge Wells and the reason there are only 8 car trains currently. Any ideas?...
