The ČD Class 840 and 841 diesel multiple units are two versions of the Stadler Regio-Shuttle RS1 built for České dráhy.

841 is the basic version, 840 is a modification for services on steep mountain lines.

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.

These have been classified as 841.2[6] This article about transport in the Czech Republic is a stub.
