The longest children’s railway line is the 11.7018-km-long (7.27-mile) narrow-gauge Gyermekvasút (The Children's Railway), running through the woods on the Buda side of Budapest, Hungary, between Hűvösvölgy and Széchenyihegy stations. Also known as Line 7, it stops at the seven stations in between for a one-way journey time of approximately 50 minutes. The railway has been in continuous operation since the first 3.2 km (2 miles) of track were inaugurated on 31 July 1948. While the trains are driven by adult engineers, all traffic and commercial services are the responsibility of children aged 10 to 14 years, working under adult supervision and in accordance with the regulations set out by the State Railways of Hungary (MAV Zrt). The railway operates throughout the year, except for Mondays in September to April. Trains run from 9 a.m. until 5 p.m. in the winter and until 7 p.m. in the summer.
