ČD Class 840 is used on services in Liberec Region. There are 16 trains in service. The maximum speed is 120 km/h,[2] while it was meant to be just 100 km/h at the time of order,[3] the unit is modified for service on steep lines and lines using rack rails. The rack rail compatibility was required to be able to serve the Tanvald to Harrachov line, but the trains themselves lack the rack railway equipment.
