The Rack Railway line, 182 Tatranská Štrba, at Štrbské Pleso is one of only two rack railways in Slovakia. The electric trains run on steep gradients and have cogwheels which mesh with a toothed rack-rail which runs between the running rails.
The current engine at Štrbské Pleso has been in operation for 48 years and the Slovak Railway Company is now planning to re-new it. Five new carriages and one multifunctional locomotive will replace the current three carriages in three years. They will be equipped with air-conditioning, WiFi connection and USB ports. The carriages will also be barrier-free and for sportsmen there will be space to store bikes, skis and snowboards and there will also be space for prams.
