The Willemsspoort tunnel is a four-track tunnel in the centre of Rotterdam (the Netherlands) underneath the Nieuwe Maas River. It is part of the Breda – Rotterdam railway line. A part of the tunnel is the very well-known underground station, Rotterdam Blaak.
The tunnel was opened in 1993 and automated with a Sattcon control system. In 2010, it was decided to completely renew this control system. In collaboration with VTN, IAS replaced the entire Sattcon control system. By means of a conversion tool developed in collaboration with ABB, the existing software was converted to an ABB Compact Control Builder with ABB AC800M controllers.
This solution allowed for fast realisation of the new control system and meant minimal downtime at commencement of operation. By now, the new operating system has been running without any problems since 2010 and the new hardware will last for many more years.
