TRANSPORT links across Hillingdon are struggling to stay in service despite the onslaught of winter with buses, trains and airports all affected.

Transport for London (TfL) is attempting to keep passengers on the move and is using its website to provide breaking news.

Further heavy snowfall is forecast throughout the day and the advice is to check before you travel and only make essential journeys.

The other ways to receive updates are:

¥ The London Travel Info 24hrs telephone helpline: 020 7222 1234;

¥ BBC Ceefax, page 436, or ITV's Teletext, page 164;

¥ Information on posters, leaflets and service boards at Tube stations; and

¥ Local media news and travel bulletins.

All bus services in London are currently suspended on safety grounds and will only resume when road conditions allow.

A TfL spokesperson said: "We're working with the local boroughs to ensure that they can do all they can to clear the roads around bus garages, so we can run services again."

Overnight engineering works were postponed on the Tube network last night to allow Tube and engineering trains fitted with de-icing equipment to continually run across the above ground parts of the network.

This ensured that tracks remained clear of snow for the start of service in the morning.

Tube services will operate today and London Underground will seek to run as many trains as possible though a number of lines are likely to be disrupted as a result of the weather.

Meanwhile Heathrow Airport continues to suffer after a plane slipped off a taxiway and lodged its wheel in the grass. The Cyprus Airways flight landed at 8.20am and was moving to Terminal 1.

Heathrow's operator, BAA, said passengers were unharmed and were remaining on the aircraft.

A BAA spokesperson said the front wheel of the plane had landed in the grass area and was being removed.

The aeroplane was the last flight to land before both the runways at the airport were closed due to snow, however the southern runway has since reopened.

British Airways has cancelled all its flights until 5pm tonight.

Up to 6cm of snow has been reported at the airport.
