The East Anglia Transport Museum will be pulling off a historical coup on Sunday with the return of the world's oldest operational trolley bus back into service.

The museum at Carlton Colville will start operating the former NESA (Copenhagen) No 5 trolley bus, which was built in 1926, to mark 100 years of the trolley bus in Britain.

Sunday's 100 Years of the Trolley Bus event will give people a chance to get up close to the No 5, which had its chassis built by the Garrett engineering factory in Leiston.

The event will also showcase the history of trolley buses from their introduction in Britain during 1911 in Bradford to their spread across the European continent up until 1989.

It will feature a ZIU trolleybus from Athens.

Sunday's 100 years of the Trolley Bus runs from 11am to 5pm and the museum's usual rides and attractions will be open.

It costs �7 for adults, �6 for OAPs and �5 for children aged five to 15 to enter and the price includes rides.

A free motorbus service will operate every half hour or so from Lowestoft's bus and rail stations to the museum.
