IC Direct is a train service connecting Antwerpen and Amsterdam Centraal. It travels on the dutch highspeed line HSL Zuid which is also used by Thalys high speed trains to Paris and Eurostar to London. IC Direct is a very popular connection in the Netherlands and the route between Amsterdam and Rotterdam has already been recreated once in Train Simulator Classic and is one of the favorites among the dutch routes. Also this suggestion would nicely complement suggestion from another user to add the route from Rotterdam to Antwerpen. Length of the proposed line I measured the length of the proposed route between Breda and Amsterdam Centraal to be around 115 km so it's not a particularly long route compared to other routes already in the game.
