That changes my thinking. I'd assumed it was probably a motorway rest stop.
If at all possible, it sounds rather like "ask the client for clarification" time to me. Given lack of context and very few search results on web.
When I tried Google Image, I got mostly pictures of trains. Big modern ones. This surprises me because "Freizeit" suggested a station on one of the little steam locomotive railways for trippers that exist in the UK (there's one called the "Romney, Hythe and Dymchurch Line" near where I live. Some of them are *run* by people in their leisure time too).

I suppose there's no mention of *where* this Freizeithaltestelle is? If there were, perhaps you could look it up (e. g. on Google Maps) and see if there's a railway station there?

No context available - do you know what kind of vehicle uses this kind of stop (coaches, cars, lorries?) Can we definitely rule out "railway station for pleasure trips"?

Speaking as a UK English speaker, we generally call those places where motorists on long trips stop off for petrol, food etc. "a motorway services", although "rest stop" is quite acceptable and probably safer.

I suppose you've looked at these
