On January 13, 2024, the State Railway of Thailand organized a National Children's Day event to bring happiness and knowledge to young people across the country. The event featured recreational activities designed to inspire and foster creativity, with enthusiastic participation from children and youth.

This year's event, themed “The Train of Happiness”, focused on providing children and youth with hands-on learning experiences to foster creativity and pride in the railway industry, which has been a significant part of Thailand’s history for over 125 years. The activities aimed to cultivate a sense of responsibility and good discipline among participants, aligning with the National Children's Day slogan for 2567 (2024) set by Prime Minister Settha Thavisin: “Think Broadly, Create Innovatively, Respect Differences, and Build Democracy Together.”
