Wagons series 810 (other designation: M152.0) is a series of freight wagons, produced in the period 1975-1982 in the Czechoslovakian Vagonka Studenka factory. 680 copies were made in the course of production.

810 series motor wagons (popularly known as "motorbikes") were designed and put into production to replace the M131.1 series wagons, and their first prototypes appeared in 1973. In order to shorten the research and development time, it was originally decided to use a bus engine to drive the new car without any modernization, but such a system did not work in practice and the engine had to be adapted to the new requirements. Finally, the LIAZ ML 634 engine was used. The passenger compartment has up to 55 seats. There is also a toilet and a small utility room in the carriages. Initially, Czechoslovak railways wanted to use the 810 series carriages only on short routes, but over time they also began to be used on medium and long routes, due to the discontinuation of the production of the M474.0 dedicated to these routes. 810 series motor carriages are used in the Czech Republic and Slovakia to this day.
