Railway Undertakings rely on high quality rail paths to be competitive in the European transport sector. Temporary Capacity Restrictions are massively influencing rail transport day by day. On the one hand, construction work is urgently needed to make the rail network in Europe more attractive and, on the other hand, current operations must not suffer as a result. In this area of conflict, it is necessary to optimize existing processes for IMs to be able to offer the needed capacity reliably and make rail transport more competitive.
