The first PLC interlocking has been in operation at Santpoort Noord station since July 2012. In December of the same year, ProRail approved implementation of the PLC interlocking solution from Movares across the entire Dutch railway network. Movares considers the ProRail approval a breaktrough in the area of train control. The combination of proven industrial hardware with railway-specific applications will result in a cost-effective and flexible product. Since its commissioning, the PLC interlocking has been working reliably and without failures. The next project has already started: In 2014, Movares installed a second PLC interlocking with COTS components from HIMA for ProRail at the Beverwijk railway station. This interlocking has been in operation since April 2015.
