The “singing” comes from the Siemens GTO-VVWF power converters which create a musical scale when the train begins to move…

Here is a clip from a 1950s safety film from America. The clip shows the danger of being too close to the railway.

In very many parts of the world the railway track is the easiest route to follow across difficult terrain. That’s because it is maintained, kept clear and because the engineering of the track bed gives a regular and even path – people walk on the track sleepers between the rails and think they will hear the train coming, and be safe.

In fact, the doppler effect compresses the sound waves of the train as it approaches, so that you don’t hear the train it until it’s really close. It’s too late by then. Nowadays, the trains are moving so fast that the danger is even greater.

If you are on the track and you can hear the train or see it; it’s is too late…

In India, many people walk on the railway track and they have a large number of accidents. The Indian authorities have begun to produce posters addressing this important safety issue.

The telegraph poles at the side of the track were a distinctive feature if the information superhighway in its analogue form. The shorter poles, in the image above, are characteristic of the USA. Nowadays, the fibre optics are in a box-trough along the track.

Here is a link to a BBC radio programme about doppler effects…

It turns out that the very first scientific experiment to show the doppler effect was carried out by trumpet players on a train…The sliding brass sound of the doppler is lovely.

Here is a wonderful post about the distinctive sounds of the bells on US railroad crossings…

Get Carter (1971) by Mike Hodges is one of the classic British films of the 1970s. The film begins with a great railway sequence, filmed on the train from London to Newcastle. The East Coast mainline…

Wolfgang Suschitzky was director of photography for this film.

I’ve posted many time about the railway and cinema, so I was delighted to find this blog dedicated to trains in films…

And here is a picture of the type fo steam locomotive shown in the poster…it’s a very famous and long-serving type of engine.

You can see these engines in the documentary film by Jean Mitry, Pacific 231 (1949).

Here’s my previous post about the film
