Security fencing will be deployed to protect a temporary bus depot that will be built for the Olympic Games in 2012.

The transport hub, proposed to be developed at a current Parcelforce site near West Ham tube station, will be big enough to house 400 buses and 1,200 drivers, the Evening Standard reported.

Olympic athletes will be ferried between venues on the buses.

The security fencing will be 2.7m high, with the area being classed as "high risk" because of the possible numbers of athletes all congregating at the site, the newspaper said.

It is expected that the hub will open in April 2012 for preliminary testing and will be taken down after the Paralympic Games, as long as planning permission is given.

Writing for the BBC recently, Baroness Ford, the chair of the Olympic Park Legacy Company, explained that the athletes' village will be converted into housing after the Games, creating 2,800 flats.ADNFCR-3337-ID-800277646-ADNFCR
