The Trolley can moved along the Greendale Light Railway manually by the use of pumping the handles up and down at either end.
It first appeared in "Postman Pat and the Runaway Train". When the Greendale Rocket runaway with the Reverend Timms stuck in the cab, Ajay and Mr. Pringle gave chase on the trolley.
Pat and P.C. Selby also used to the trolley to search for the missing Greendale Rocket in Postman Pat's Missing Things.
