The original Kingston Flyer was a passenger service that operated between Kingston and the Main South Line at Gore from 1878 through to the mid 1950s. It provided a passageway to Queenstown and the surrounding stations, by meeting up with the lake paddle steamers at Kingston Wharf. The train ran later as a tourist train from several different routes, the latest was Kingston to Fairlight until 2013, the train has been left abandoned since then and is up for sale.
Gaynor ran the catering carriage.
