France's State Railway, SNCF, has sparked controversy with its new 'Optimum Plus' first-class section on selected trains, which is not accessible to children under 12 years old. The new class, introduced in January, offers a 'quiet dedicated space' for business travelers, but has been criticized for giving the impression that adult comfort depends on the absence of children. This has led to concerns about France's stagnating birth rate and cultural attitudes towards children. However, SNCF has defended its decision, stating that the new option is aimed at business customers and those who want a 'special travel experience with personalized assistance and flexibility'. The company also emphasizes that children are welcome on board, offering family fares and areas, and welcoming 300,000 children annually through its Junior & Compagnie program. The controversy highlights the complex relationship between travel, comfort, and cultural values, inviting further discussion on the role of children in public transportation.
