I've seen a few posts here recently asking about travelling around Switzerland by rail - where to go, what routes etc.
It reminded me of an old TV series that used to run in the UK and was great "relaxing Sunday afternoon" TV.
It was made in the mid-90s so obviously the practicalities have changed in some cases - and it's definitely dated in terms of style, presentation and production values (which were never particularly high to begin with). It also can't quite decide if it's a travel show or a nerdy railway history thing. BUT all that aside, it's got some great landscape shots and is a great intro if you're coming from a place of "well I've heard the trains in Switzerland are great but that's all I know" - or you just want to watch some lovely scenery.
