Pretty sure you're thinking of the several Rhatische Bahn routes. As far as I can tell, this is not a route for TS. Both are pretty neat railways, though.
That's fine, the two railroads hgave somewhat similar operations IRL anyway so the Bernina Express route being popular could still make this popular. In fact, the Glacier Express runs across both routes.
This one should have an advantage over Rhb is that instead of Adhesion to Ascend and descend the mountains this one uses a rack railway to ascend and descend mountains.
This would be really nice, maybe from Rivet Games after they have done some more RhB-routes. But it will probably need a core-update to add the cog-railways. This way, we might get the whole Glacier Express Route. That would be lovely.
I agree and Swiss Cog Railways they use tend to use Strub Riggenbach Locher & Abt systems. MGB is an Abt Rack System like the Welsh Snowdon Mountain Railway and the American Pikes Peak even though they upgraded it to a Strub Rack System.
How about the Furka Base Tunnel to Gosnochen Gotthardbahn via Andermatt. Rack section is Gosnochen Andermatt. MGB locomotives can run both Arosa and Furka Base Tunnel to Gosnochen due to them being Rack and Adhesion equipped. A tutorial must instruct the player on how to ascend/decent a rack section
The rack system would be unique to tsw, why not. Even if i prefere the rhaetian railway, mgb would be nice too. Their ge 4/4 is a different one to the rhb type.
