About 1,600 people are predicted to have enjoyed seeing a part of London's transport heritage at a special record breaking two day event at a north Suffolk museum.

The East Anglian Transport Museum at Carlton Colville, near Lowestoft, displayed and operated eight London trolleybuses today and on Sunday to mark the 50th anniversary tomorrow of when they stopped trundling along the capital's street.

Including among the venerable electric powered vehicles was the London very first trolleybus, known as the Diddler from 1931.

There were long queues to get into the museum as a estimated 800 people are due to visit on each day.

They then lined up to take a nostalgic journey on several of the trolleybuses, which fell out of favour in 1962 due to the cost of electricity and lower prices for diesel and petrol.

The museum took two years to organise the event, which was the largest gathering of existing London trolleybuses in recent years and which will probably not happen again.

Four of the vehicles are from the museum and the other four came from museums in London and Yorkshire.

Ken Blacker, secretary of the transport museum, said visitor numbers during the two days so far had been 'phenomenal' to the museum, which normally gets 16,000 visits a year.

He added: 'I think we can say that we have got record visitor numbers for two days.'

To mark the 60th anniversary of London trams ceasing operation in the capital the museum also ran its 1858 London tram.
