Children's Railway: the Gyermekvasút railway, a narrow-gauge service running in the hills above Budapest, is operated by children.

Ticket office: Under adult supervision, the kids sell and check tickets, work as guards, handle signals and staff stations.

Train drivers: The engineers and the train drivers on the Gyermekvasút -- or Children's Railway -- are grownups.

Anniversary: The railway is celebrating its 70th year in 2018. It was created in 1948.

Salutes and smiles: The children wear smart railway uniforms in the railway's red, white and blue colors.

Ticket inspection: The railway is hangover from the time when Hungary was a satellite state of the Soviet Union. Originally called the Pioneer Railway, it was intended to teach children teamwork and responsibility.

Cheap ride: Tickets cost a few hundreds forints, or between $2 and $3. It's great value for money.

Leafy landscape: While the railway is an attraction in itself, the ride through the bucolic landscape of the Buda hills above Hungary's captical city is just as alluring.

Retro station: The station at Hűvösvölgy still maintains its retro nostalgic glory. Social realism blends in with the vintage photos and bilingual signs in Hungarian and Russian.

Railway museum: Hűvösvölgy station has a small museum with communist relics such as old uniforms and a huge ticket machine made out cast iron.

Nostalgia trip: For some older Hungarians a ride on the children's railway is a nostalgic step back in time to their own childhood.

Along the tracks: Sometimes the children call out to each other from the window of the carriage after signaling and saluting.

Cogwheel railway: Those ending their journey at Széchenyi-hegy can ride another unusual train -- the cogwheel railway down plunges back down the wooded slopes.
