The class M 221.0 railcar was a four-axle, twin-engine benzene - mechanical railcar for mixed traffic of the former Czechoslovak State Railways (ČSD). It was one of the first types of twin-engine motorized railcars with mechanical power transmission from the ČSD.
History and commitment
The railcar was apparently created in 1927 as a comparison vehicle to the railcars of the same category from TATRA . The manufacturer Adamov had little experience in the construction of railway vehicles so far, and so the car was composed with construction elements of foreign origin.
Only the car body was important from the manufacturer Královopolská Brno , and so the railcar had the same fate as the first M 210.0 railcar produced , only as a twin-engine variant. It did not attract much attention in the company, so it is not surprising that it was converted into a sidecar as early as 1933.
It is all the more astonishing that the car has been preserved to this day. One can only guess about his future fate, but at some point he must have been sold to Hungary . The photo from 2007 shows it in very good condition, parked in Budapest under the designation 80 55 11 79 037-2. It can therefore be assumed that another contemporary witness from the 1920s has been preserved.
technical features
The railcar was originally powered by two 4-cylinder four-stroke engines from Mercedes-Benz . The engine had cylinders 150 mm in diameter with a piston stroke of 170 mm. The 4-stage mechanical transmission of German origin was hydraulically controlled. The torque was passed on on the output side via a cardan shaft to the respective inner drive axle, so that the axle sequence was the same as with the other twin-engine railcars.
The Královopolská car body was built on the same principles as the other twin-engine railcars, only it was significantly shorter. He had two 3rd class compartments.
