Passengers using London Bridge Station on Sunday found themselves in the middle of a giant experiment as Network Rail tested its arrangements for dealing with the large crowds expected during the Olympic games.
The only entrance to the mainline station was via the high-level concourse next to the bus station, whilst those heading to the tube were asked to use the Duke Street Hill entrance.
Passengers arriving at the station by train were directed to leave via Joiner Street.
There were few signs indicating where passengers should go, and those that did exist were unlikely to be comprehensible to those not familiar with the station layout.
A combination of the large numbers of people leaving the river pageant and the poor weather meant that big crowds built up around Tooley Street and Duke Street Hill. Metropolitan Police and British Transport Police officers supervised the operation.
A further test of the Olympic arrangements is planned for Thursday 7 June.
Last month Network Rail's Robin Gisby told a House of Commons select committee that at certain times during the Olympic games trains will run non-stop through London Bridge to and from Cannon Street and Charing Cross.
Further details of these arrangements have now been revealed. Crawley MP Henry Smith has published an extract from a Network Rail briefing for parliamentarians which says:
"This means passengers for Southeastern services (which normally use platforms 1-6) at London Bridge will need to use Cannon Street or Charing Cross stations to get their train home. This does not affect Southern passengers using platforms 8-16."
