George Bennie Railplane
This was an experimental, propeller-driven suspended monorail invented by George Bennie from Glasgow, who claimed it would reach speeds up to 120mph (193 km/h).

George Bennie began the concept in 1921 and the experimental car was built between 1929 and 1930, designed with the assistance of engineer Hugh Fraser. The car was built by William Beardmore & Company.
Location: Milngavie, Glasgow, Scotland
The 426ft (130 m) elevated test track stood immediately east of Main Street, Milngavie, above a London & North Eastern Railway (LNER) siding to Burnbrae Dyeworks. Today it’s just east of the Kelvin Timber premises.

Bennie’s vision of transport for the future - and the harsh reality
Between 1929 and 1930 George Bennie built a trial stretch of track with one railplane car at Milngavie near Glasgow as a demonstrator. He invited potential clients to sit in the comfortable carriage and take a ride along the short track. The railplane ran along an overhead monorail, with guide rails below. The power was supplied by propellers attached to on-board motors, front and rear.
Bennie’s plan was to build the overhead gantries above existing railway lines. A speed of 120 miles per hour (193 km/h) was claimed, although it could never be tested and confirmed. His railplane would offer fast passenger and mails and perishable goods service. Each car on the railplane could carry a maximum of forty-eight passengers.
George Bennie could not obtain the financial backing he required to develop his transport system. Sadly, the derelict prototype railplane and supports were sold for scrap in 1956.
