London 2012: Rail bosses urge spectators to drive to Weymouth
Rail bosses have recommended that spectators travelling to the Olympic sailing events in Weymouth go by car.
South West Trains has warned there could be significant disruption during the Games, with an extra 80,000 passengers a day on its network.
The firm will provide extra services as it runs at up to 40% extra capacity.
But the limited power supply on the line to Weymouth, which was electrified in the 1980s and has a single track on part of it, will affect services.
