London Underground have announced that from next Monday, 19 April 2010, until summer 2011 Oxford Circus station will be exit and interchange only before 10.30 am on weekdays.
That means that before 10.30 am on weekdays it will not be possible to enter the station at street level to join the Central Line, the Victoria Line or the Bakerloo Line. The restrictions may also be implemented at other times if the station gets too busy.
It sounds bad, but the reality is that these restrictions shouldn't affect the majority of passengers. The access arrangements are being implemented to allow engineers to replace a bank of three escalators.
