I have booked a ticket from Amsterdam Centraal to Bruges (via Bruxelles Midi) on April 18, 2018. I have been checking the weekends for the return trip on 21 April - which is a Saturday. I know I cannot book it until December 21, 4 months in advance.
However, I have been checking the schedule for Saturday and Sunday travel on April 7,8, 14 and 15 and the only trains available are IC trains. I am wondering if there is going to be track work on the weekends in April and the Thalys trains will not be running.
