Bennie was born in Auldhouse near Glasgow in 1891, and began development of his railplane concept in 1921. A 119 metre long experimental track was built in Milngavie in 1929 (on the current site of Kelvin Timber). While a fully operational line was proposed between Glasgow and Edinburgh, it failed to attract enough financial backing and in 1937 Bennie, who had paid for most of the development himself, was declared bankrupt. The prototye railpane was eventually scrapped in 1956.
