@daveybunce I’m not TfL but I believe I know the answer: it will involve barriers but the system will charge you a single through fare (the exit and the entry are connected so the system is clever enough not to charge you twice).
@kiran_gupta@TfL Just passed through the station. Apparently there is an unstable structure at Platform 4 which means trains towards London are skipping the station.
Question for @geofftech…do district and circle lines use different platforms at Tower Hill? The Circle Line is reportedly 20 metres further from Tower Gateway yet 60 metres closer to Fenchurch Street?
