Late-night trains will be laid on between Bristol and London during the 2012 Olympics.

Games organisers plan to hold talks with train operators to put together a timetable that would increase the number of services during the three-week event in East London.

Travel across London should also speed up significantly with the creation of a seven-minute Javelin shuttle service from St Pancras station – a short Tube journey from Paddington, where Bristol trains terminate.

Olympics chiefs hope the overhaul will allow fans from outside the capital to watch events without having to stay overnight, as well as making it easier for families to make the trip.

Former Olympic triple-jump champion Jonathan Edwards, deputy chairman of the London Organising Committee's nations and regions team, said: "It is something we are looking at. There will be extra trains, buses and coaches so people can do the games in a day."

Mr Edwards was speaking during a tour of the Olympic Village organised to highlight the contribution Bristol and the South West has made to the games, which the Government pledged will benefit the whole of the UK.

Two Bristol schools are among the first in the country to get involved in the Get Set Programme, which aims to get children interested in the games.

John Cabot Academy and Bristol Brunel Academy Federation want athletes to talk to pupils, carry out projects in class on the Olympics and work with overseas schools to help "bring the games alive".

So far 30 companies from the Bristol region have won contracts – more than half of tenders have gone to companies outside London – and Edwards believes the area has yet more opportunities.

"If it ends up with large parts of the country that feel excluded then we have got it wrong.

"I understand the natural cynicism, it's part of the British psyche, but there is a real commitment to make sure the benefits are pushed out far and wide," said the triple-jump world record holder, who lived in Bristol as a child.
