DescriptionThe conductor of South Shields 204 demonstrates a 'frog pull'. This moves a 'frog', a set of points in the overhead wiring, to enable the trolleybus to access a turning circle. Once the trolleybus booms have passed through the conductor will release the handle and the frog will reset itself for the straight-ahead wires. South Shields 204 is a Weymann-bodied Karrier E4 which entered service in 1937. When it was withdrawn in 1963 it was donated to the Reading Trolleybus Society, one of the four organisations which went on to found the Trolleybus Museum.
