Scotland’s Railways

Railway role: Inventor

  • Robert Davidson

    Robert Davidson (1804–1894), an Aberdeen chemist and experimenter, built an early full-size electric locomotive and demonstrated it on a working Scottish railway. His achievement was a proof of possibility, not the beginning of an immediately practical electric service.

    Electricity before the power station

    Davidson worked when useful electric motors, generators and distribution networks were still emerging. He experimented with electromagnets powered by galvanic batteries and constructed small electric machines, including a model railway vehicle. Public exhibitions in Aberdeen and Edinburgh presented electromagnetic machinery to paying audiences and scientific observers.

    His most ambitious machine was Galvani, a full-size battery locomotive. Its motors used electromagnets acting on iron bars attached around rotating wooden cylinders. This was ingenious but inefficient, and its primary batteries were costly and could not simply be recharged from a public electricity supply that did not yet exist.

    The Edinburgh & Glasgow trial

    In 1842 Galvani was tried on the Edinburgh & Glasgow Railway. Accounts describe the several-ton locomotive hauling a load at about four miles per hour over a short distance. That performance could not compete economically with steam, but the trial demonstrated that electromagnetic power could move a rail vehicle at full scale.

    Later retellings sometimes turn the episode into a clean “first” followed by sabotage from threatened railway workers. The pioneering nature of the experiment is well supported; the story that the locomotive was deliberately destroyed is much less securely documented and is therefore not treated here as established fact.

    Why Davidson matters

    Davidson did not create a commercial electric railway, and the technology available to him could not sustain one. His historical importance lies in testing the idea against real railway conditions decades before electric traction became viable through improved motors, generators and power supply.

    His place in Scotland’s railway story is therefore experimental. Galvani belongs beside later successful electric systems not as their direct blueprint, but as a striking early demonstration of a different motive power on the rails between Edinburgh and Glasgow.

  • George Bennie

    George Bennie (1891–1957) promoted one of Scotland’s most visually memorable transport experiments: a streamlined passenger car suspended beneath an elevated track. The Railplane promised speed above existing rail corridors, but it never became a commercial railway.

    An idea above the railway

    Bennie imagined fast passenger vehicles running on a dedicated overhead structure while slower goods trains continued on the conventional railway below. The concept separated traffic by speed and function rather than adding another pair of ground-level tracks. Patents and publicity turned the idea into the “Bennie Railplane”.

    Precision about authorship is essential. University of Glasgow Archives describes Bennie as the inventor and promoter, not as the engineer who designed the working system. Consultant engineer Hugh Fraser carried out that role, and William Beardmore & Company built the experimental car and structural components.

    The Milngavie demonstration

    A short test line was erected at Burnbrae near Milngavie, above a siding associated with the London & North Eastern Railway. The propeller-driven car ran beneath the girder track, steadied by lower guide rails. Demonstrations in 1930 attracted attention from engineers, journalists and the public, and surviving film preserves the extraordinary sight.

    The installation proved that the vehicle could run, but it did not prove a complete transport system. A commercial route would have required major capital, stations, junctions, operating arrangements and confidence that its advantages justified an entirely separate infrastructure.

    Failure without ridicule

    No full Railplane route was built. Bennie struggled to secure investment and was bankrupt by 1937. The test structure remained a landmark until it was dismantled in the 1950s.

    It is tempting to present the Railplane either as a lost future or as an eccentric folly. Both readings flatten the evidence. It was a serious, engineered demonstration of an ambitious idea whose commercial and system-level case was never achieved. Bennie belongs in the history of railway imagination — with Fraser and the industrial workforce kept visible beside him.
