The head of London's transport system says there are no plans for bag checks on the subways as part of extra security planned for the Olympics next year.

Peter Hendy, the commissioner for Transport for London, says that while authorities will take advice from the police, such additional checks are not envisioned on the Underground.

But Hendy said Wednesday that surveillance camera use would be expanded for the summer Games.

Critics of London's aging transit system had expressed fears that additional security measures would further delay journeys on the Underground, known locally as the Tube.

The system will be stretched to its limits during the Games. Bags are expected to be checked at venues.
