As the title refers to, are there any freeware high speed routes out there? Such as the TGV, or whatever else they're called?
I've been tempted to purchase a payware route for this purpose, before I realised that spending $20-40 may not be necessary for what could be 30 minutes of driving at the most. I'm referring to operational speeds of around 250kph or higher, but I wouldn't mind driving on a UK HST route if there are any recommended freeware ones around the place.
So assuming there are any, which ones would be recommended in regards to the availability of rolling stock and scenarios?
