\r\nOperator Keyrail, a joint venture of Dutch infrastructure manager ProRail, which holds a 50% stake, and the port authorities of Rotterdam and Amsterdam which hold respective 35% and 15% stakes, says the result is due to the activities of new train opertors on the line. Increases in bio diesel, dry bulk and waste transport have made up a substantial part of this increase. However, the outlook for 2012 does not look as good. Keyrail says that the economic uncertainty in Europe is likely to impact traffic. Nevertheless, Keyrail plans to open up more markets, specifically by establishing greater cooperation with the ports of Rotterdam and Amsterdam. According to local media reports, Keyrail is likely to secure the concession to continue operating the line from 2013 to 2023 when it is awarded by Dutch infrastructure manager Mrs Melaine Schulz van Haegen-Maas Geesteranus.
