COMMUTERS around South Bucks shrugged off fears of further bomb attacks on Friday as they travelled into London to continue their normal working day.

The four bombs which exploded in the capital on Thursday three in the London Underground caused commuter chaos, cancelling Chiltern Railway services and closing most underground stations.

On Friday, commuters travelled into London Marylebone via services from Amersham and Denham, with rail replacement buses escorting passengers between Amersham and High Wycombe every 20 minutes.

Three trains an hour were running between London Marylebone and Denham.

High Wycombe Train Station was not as busy throughout the day. As commuters returned to High Wycombe on Friday evening, many stopped to recount their experiences of the previous morning, which has so far officially claimed the lives of 52 people.

Ciaralli Parenzi, from Marlow, was on an underground service from London Marylebone to Baker Street when his tube stopped short of its destination before 9am. Mr Parenzi, who works in Westminster, said: "About 9.20am they started going from Baker Street and the driver said there was an incident. We had been stuck in the tunnel for about a quarter-of-an-hour which seemed normal for the underground. I was quite calm. We were told there was an incident in front of us and we started to think it was serious."

John Trevor, of Totteridge, High Wycombe, had travelled to work in Victoria, London.

Mr Trevor, 42, said that the atmosphere on the underground had been "tense" and that people had been looking at each other suspiciously, as if they feared more bombings.

He also said that although he was apprehensive about going back to work, he had experienced similar dramas.

He said: "I was working in Harrods when they had an IRA bomb years ago. I don't see any reason why it should stop people going into London now. Life has to go on."

On Saturday, Alison Hughes, 25, who works in London and was visiting her boyfriend in Marlow, said she was lucky to be alive after deciding to take a later tube into King's Cross.

She said: "We were told around 9.15am at King's Cross there was a power failure but I thought it was more than that. I was very lucky it was upsetting."
