The M 262.0 series railcars were produced in 250 units from 1949 to 1960 by Královopolská , Brno and Tatra Studénka and delivered to the ČSD. The vehicles up to number 052 were manufactured by Královopolská, the remaining vehicles were then manufactured by Vagonka Studénka . The appearance changed several times. The vehicles manufactured by Královopolská had the box with the flat roof, the grilles as transition protection, the large front windows and the arrangement of the tail lights above the headlights. The first vehicles manufactured by Studénka (from company number 053 to 140) still had the appearance of the first vehicles from Královopolská with the flat barrel roof, the transition grilles and the large front windows, only here the tail lights were placed under the headlights. From road number 141, the vehicles then carried the arched barrel roof with sheet metal as transition protection and smaller front windows. From this design on, the railcars also received one of their many nicknames; Kredenc (German: kitchen cabinet ).

The vehicles were powered by the 12 V 170 DR engine with an output of 302 kW and had electrical power transmission. The output of the generator is 260 kW, the two drive motors each have 130 kW. Some vehicles were equipped with new engines in the Šumperk repair shop in the early 1980s and classified in the 831 series.

The M 262.0 series railcars have shaped passenger and express train service on non-electrified routes with medium traffic for decades. In Germany they became known through the corridor traffic between Varnsdorf and Liberec via Zittau . The robust, reliable and undemanding vehicles enjoyed great popularity with staff and travelers. Because of the noise they make when driving, they were nicknamed “sewing machines”.

One of the last operational routes of the vehicles was the current timetable route 073 Děčín - Ústí nad Labem - Střekov until 2006 . The last vehicles were used on the Jeseníky Mountains in 2011 and retired in Šumperk in the same year .

The railcars of the M 262.0 series were, along with the Romanian Malaxa railcars, the oldest diesel railcars in regular service in Europe. Some specimens have been in use for over 60 years. Many of the vehicles have been preserved, some of them in working condition for clubs.
