The infrastructure of the ERTMS track section between the Dutch yards Kijfhoek and Roosendaal will be set up in such a way that shunting locomotives on the railway yards in Lage Zwaluwe and Roosendaal can continue to shunt without ERTMS for the time being. The advantage of this is that old shunting locomotives do not have to be converted immediately, says ERTMS programme director for the Netherlands Wim Knopperts.
