In the past few years the technical and safety needs for railway tunnel systems designed for a cross travel speed of more than 160 km/h caused a steady increase of tunnel facilities. In addition to the structural engineering experience required, a more sophisticated approach of planning the highly complex tunnel equipment is needed - also to comply with the permanent on-going change in the legal framework. Experience in the operation has shown that due to the high complexity the tunnel facilities not always work in the way expected (e.g. failure indication) and that facilities in tunnels are often not designed in consideration with other interacting facilities (e.g. tunnel doors and tunnel ventilation). It becomes apparent, that in the future an integrated design of the tunnel facilities is mandatory. This to take part already in the design phase of a tunnel. Various issues with doors in recently opened tunnel-systems forced an evaluation that subsequently led to a review of the specifications of tunnel facilities, especially doors.
