• * For 2018, these indicators were changed due to technical adjustments to the measurement system.

Punctuality for passengers (to 5 minutes) was 82.5% in 2018 (83.5% in 2017). There was an anticipated decline after the introduction of the Eurostar and the IC Brussels, which started running on the HSL in 2018. In addition, in 2018 the software was updated by the supplier of the HSL trains. However, this update did not bring the desired improvement in performance due to an error in this update. Trains ended up briefly stranded as a result, and this is reflected in lower punctuality figures in the second half of 2018. It was not possible to correct the error in 2018 and that work will continue in 2019. Despite the poorer performance, NS achieved the minimum value for this KPI in 2018.
NS and ProRail continue to pay constant attention to the performance of the HSL South. A long-term vision for the HSL South to make lasting improvements to performance on this line was submitted to the ministry.
