France Introduces Child-Free Train Carriages

France's train company, SNCF, has started a new thing called 'Optimum' on some of their trains.

This is a special area just for adults, where kids under 12 aren't allowed.

The idea is to give grown-ups a quiet place to work or relax.

Some people think this is a great idea because it means adults can enjoy their trip without kids making noise.

But other people, like some politicians, are upset because they think kids should be welcome everywhere.

They say it's not fair to make kids feel like they're not wanted.

The child-free area is only on a few trains and only during the weekdays when lots of people are traveling for work.

So, most of the time, kids can still play and move around on the other parts of the train.
