It could be chaos on Dutch rail too the coming day. Trimmed down schedule on some of the busiest routes (due to the current heatwave). Add to that a labor union strike on Wednesday June 24 (that's today local time as I write this).

Although NL rail travelers are usually quite good at anticipating, and adjust their schedule. So might just be a quieter-than-usual day.

It helps that 90% of the population can cycle to work if they have to. Remote work is also very big.
