Filmed on the Longmoor Military Railway.
As "Matilda" and the mail van approach the station where they eventually crash, there is a brief establishing shot of the station, before the first shot of the station master and the chief constable on the platform. The same shot, with the addition of "Matilda", is seen as she crashes into the buffers. This shot is a modified version of a painting "London Midland Electrification, Stafford Station" (1963), by John Greene. The buildings match, but the different trains and people have been drawn for the film. The pantograph of the original electric train in the painting has mistakenly been left in, apparently sticking out of some old carriages of a steam train.
