Intercity Direct, abbreviated to ICD, is a Dutch category of higher-speed train service, operating on the HSL-Zuid and connecting Amersfoort Vathorst / Lelystad to Amsterdam Zuid, Schiphol Airport, Rotterdam Centraal and Breda.
[1] An hourly domestic service branded Fyra by operator NS Hispeed was started on 7 September 2009 between Amsterdam and Rotterdam using TRAXX-locomotives and ICR-carriages.
[2] An international service also known as Fyra between Amsterdam and Brussels started 9 December 2012 using V250 rolling stock of AnsaldoBreda.
From 17 January 2013, this service had to be pulled due to undercarriage damage caused by high velocity with ice and snow.
[3] Due to the perceived bad reputation of the Fyra brand, the domestic service rebranded into Intercity Direct as of December 2013.
[6][7] As of December 2024, Intercity Direct will no longer stop at Amsterdam Centraal due to the station's renovation.
