Train services at London’s Gatwick Airport in the UK have temporarily ground to halt because of a £45m upgrade, which will see trains be replaced by buses for the next ten months.

The upgrade is part of BAA’s £1bn investment programme.

The new service is expected to begin by May / July 2010 and become fully operational by 1 August 2010.

The train service will eventually connect the north and south terminals.

An extra travel time of 20 minutes between each terminal has been advised to passengers.
