Quite the detour, especially the turn towards Gossensaß that's only done to gain the altitude slowly enough, to not need yet another train engine for pulling freight over the Brennerpass; currently they're using two and also have an exception that allows to pull more power from the track grid than normally allowed by law/regulation. Rail wise it's planned that this tunnel shaves off an hour of travel time between the two provincial capitals Bozen and Innsbruck, which would be quite welcomed by myself; traveling between Vienna and South Tyrol quite a few times by train. Out of interest, is this software specially programmed for the job or is it a general geological/tunneling planing suite? Also, what company would that be (if you don't mind sharing)?
