Hi,
First, you are right for Bruschal. I found strange that trains had to maneuver.

Next, yes, I only include new infrastructure or highspeed infrastructure (normally, the Magistrale for Europe is only these types of ways). So that's what I did.
But for the Vienna-Bratislava section, I see the line, but the map say that's not a highspeed line (only ways with a max speed of 160km/h) . That's possible that I made a mistake. In this case, could you tell me your source ? Like that I'll can change the relation.

Thank's for your comment !
