What's the best strategy for winning while using all 3 stations in Ticket to Ride Europe?
Play with 2 or 4 bots. You'll be needing stations more with more competition for routes. Why 2? because you don't get the second half of the doubles without 4 players total. This means that to win, you'll more likely need to make more connections through occupied chunks.

If winning cleanly, grab some tickets, and take one or two that you can connect by dropping a station.
