A model railway is shown - the train is a prototype for a vehicle that can climb steep hills.
No title. c 1920
C/U of an unusual model railway. A model train speeds along through some metal archways away from the camera. C/U of man who is presumably the owner of the model railway. He holds a model train, pointing out certain features to the camera. He turns the train to show the wheels on the underside. He moves them around.
Intertitle reads: "Neither a mono-car nor an ordinary one.... but it can climb 1 in 7 gradients with ease. L/S of the model track. Shot of the train/car climbing up the steep tracks. The contraption can glide around sharp curves also. C/U of the nose of the vehicle as it turns a bend in the track. L/S of the vehicle travelling along a straight piece of track and then up and down a 1 in 3 gradient. Shot of two of the trains passing one another.
One of the models is subjected to: "A stability test that would push the ordinary train out of focus." The inventor turns the model on its side whilst it is attached to the track. It doesn't fall off. He then shakes the track vigorously. The model stays put. The inventor holds a small piece of stick up to the camera. He then places it on the tracks and shows how the train will drive right over it. We see the train do this in close up.
Note: although this looks similar to the "George Bennie Railplane" I am reliably informed that this is another inventor - name unknown.
