The Pump Trolley is a railway vehicle with a pivoting arm mounted on it, which is pushed down and pulled up for propulsion by two people standing on both ends.
In its first appearance, Old Bailey took the Pump Trolley to get around his old line, watching for broken signals or collapsed viaducts. He once used it to alert to Henry, after the big green engine accidentally pushed some trucks into a ravine.
In the CGI Series, it is used by the Workmen for maintenance work. Sir Topham Hatt and his helpers would occasionally use the Pump Trolley as a private mode of transportation when the engines were not available, most notably around Misty Island.
