Dear User, All routes that have come so far were only from England or Germany but not yet from Switzerland or Austria my idea for a new route is from SBB CFF FFS from BLS (Bern Lötschberg Simplon) or RBS (Regionalbahn Bern Solothurn) or SBB (Schweizerische Bundes Bahn) Idea Routes From Basel SBB To Interlaken in many Routes Like InterCity or InterCity Express with Stops in Basel Liestal Olten, Bern, Thun, Spiez and Interlaken, (Thats the SBB Route) Bern, Münsigen, Thun, Spiez, Here a Split, Spiez - > Interlaken or Spiez, Brig or Spiez Zweisimmen (BLS Route) last but not least, Route Bern, Solothurn for RBS
Switzerland would be pretty cool since what you said there is no current route outside the UK, Germany and USA. Licensing might be tough for DTG, but I'm sure a lot of people will buy it since it is a unique route. +1 from me
