East Anglia's roads and railway lines are expected to be busy this weekend as travellers begin their journeys home after Christmas or set out for a bank holiday break.

Drivers and train passengers look set to avoid any major travel chaos as the temperatures remain above freezing.

However train passengers to and from Norwich will face longer journeys due to engineering works. Fog may also cause problems this morning for motorists on the region's road and planes arriving at or leaving Norwich International Airport.

Monday is expected to be the busiest day of the bank holiday weekend for National Express East Anglia trains as people travel to and from Norwich after staying with relatives over the extended festive period.

Because of engineering works outside London between New Year's Day and Monday passengers on hourly trains to and from Norwich will have to get on a bus from Ingatestone, Essex, to complete their journeys.

From Ingatestone the replacement bus service will go to Newbury Park station where passengers can get on the Central Line to reach Liverpool Street station.

A National Express East Anglia spokesman said: 'It is going to be our busiest day on Monday as most people will be returning from the Christmas break.

'We would advise people to leave enough time for their journeys to and from Liverpool Street between New Year's Day and Monday.'

Today because of the works trains will run hourly into Liverpool Street during peak times and half hourly during off peak times.

On New Year's Day there will be slightly amended Saturday services for local trains in Norfolk and on January 2 and 3 there will be a Sunday service.

According to an AA survey there will be 'localised congestion' around major retail outlets in the region over the weekend. It is also predicted 36pc of motorists will go out on East Anglian roads on New Year's Day.

Apart from fog this morning motorists in Norfolk should face no major problems as they drive across East Anglia with temperatures falling from 5C(41F) to a minimum of 1C(38F) from tomorrow.

There is a chance the north east of Norfolk may see sleet by Monday.

Emma Sharples, a forecaster at weatherquest based at the University of East Anglia, said: 'I do not think we are going to see any problems over the weekend.'
