What does ‘over an hour delay in accessing train services’ mean? Surely trains won’t take an hour longer to travel from London Bridge to Stratford on the Jubilee Line?
Train services will continue to run to their timetable, as far as possible. However, without action from businesses to reduce normal journeys, demand for London Underground and mainline rail services will exceed the total capacity of train services and key stations, and it will take longer to access stations, platforms and therefore train services. So, without a reduction in normal journeys, it could mean, for example, queuing for over an hour to reach a Jubilee Line train at key stations at certain times.
