No need for a train. I could find conversational French/Spanish/German really easily where I live now in London. I have at least 5 native speakers of each of those languages who are friends and live within a mile of me. Right now it is just laziness.

Finding local language communities locally might be harder in less cosmopolitan areas but it just takes a bit of effort.

As an 11-16 year old learning those languages at school it was a lot harder to do so.
