The Dutch Railways apologized on Sunday for having a football song about Jews on the intercom. That happened on the night train from Tilburg to Rotterdam.

According to a spokesperson for the Dutch Railways, "there were enthusiastic colleagues who wanted to adapt the broadcaster to travelers who were on the night train from Tilburg at that time during the carnival. We understand that they have heard a pro-Ajax football song."

A traveler complained on Saturday night on Twitter that the song "Where do Jews come from?" by the intercom of the train set.

Among other things, the Center for Information and Documentation Israel (CIDI) responded indignantly to the incident. "I find it painful and too stupid to state that this has to be done on a train from NS. We cannot accept this," the foundation says on Twitter.

The Dutch Railways (NS) say they think making the song "totally inappropriate". "NS is a diverse company, we want to radiate that too. Something like that doesn't fit in, we apologize for that.

The transport company has addressed the train staff concerned about their behavior.
