I stumbled across this website/blog a few nights ago when I was looking for a particular film. It lists and has discussions about an amazing catalog of films that involve trains, many familiar but many more I have never seen ---- https://moreobscuretrainmovies...01/sudden-fear-1952/
A friend of mine brought over a DVD of an wonderful English movie from the early 1950s called "The Titfield Thunderbolt," which is about the efforts of residents of a small English village to save their branch line from closure by the government after WW-2 in the era of rationalizing English railways with the so-called "Beeching Cuts." I remembered it vaguely from seeing it with my parents when it first came out, and it is still a great movie featuring and one old and one ancient but beautiful English steam locomotive.
