Was the Eurostar delayed, does anyone know?

My experience was good: on my way in Paris -> Brussels arrived 10min early, and on my way out Brussels -> Paris I had ~15min delay (apparently because Police had to board the train before Brussels).

No, I don't think Eurostar was affected at all.

Eurostar was fine for me. Getting to the Eurostar within Germany apparently sucked for some. But I took a later train and didn't have issues there either.

Worked for me from Amsterdam.

Not for me.

Trains coming from the east via Berlin->Cologne were significantly disrupted.

As usual, there is hardly a day that doesn't happen, and it got worse this year as they finally started some repairs on critical routes, suppressing many alternatives, or average speeds.

Strikes are normal when politicians wants to steal pensions.

In Europe it repeats every year. Politicians try to steal pensions, workers strike, politicians back off. In America I think the workers would roll over. I wish the workers good luck and I will tolerate the temporary transport disruption if that's the cost of not being America.
