One of Southwark Station's two ticket offices is to be permanently closed as London Underground introduces a 35-hour working week for station staff.
The western ticket office, which is only accessible to passengers alighting from National Rail services at Waterloo East, will close from 5 February.
At present the ticket office is open between 7am and 11am.
Tube bosses say that the advent of the Oyster card has led to a significant reduction in the demand for paper tickets – one million fewer paper tickets are now being sold each week.
There will be no reduction in staffing levels across the network – ticket office staff are being redeployed to other roles.
A London Underground spokesperson confirmed to us that the ticket office closure won't affect the use of Southwark station as an easy exit from Waterloo East's overground platforms: "Platform tickets have always been available in the ticket machines so that passengers leaving Waterloo East mainline station can use Southwark Station as a short cut to Blackfriars Road when the ticket office is closed."
