The bottom half are BR official or the national museum collection as in the early 60s, and I would guess are not uncommon.
The two top right are interesting - the Monte Generoso rack line near Lugano was IIRC the last Swiss mountain lines to be electified; the loco looks to be a diesel or possibly steam. To the right is a funicular, presumably also Swiss - I don't recognise it but Lugano again, or Locarno?
The top left two look to be part of a series, maybe early 50s, and might interest specialists - of which I am not one!
