The "Slovenska Strela" M 290.0 series rail motor coaches were produced in 1936 for the then Czechoslovak State Railways (ČSD) by Tatra in Koprivnice. The coaches possessed extraordinary design of the body, a very aesthetic rendition, and, above all, a unique electromechanical power transfer system by Josef Sousedik. Thanks to his patent, the coach was driven mainly by its electric drive - the mechanical transmission was engaged as the speed increased. The vehicle reached a speed of up to 130 km/h, touching 148 km/h during testing.
Two manufactured coaches, marked M 290.001 and 002, were put into operation on July 13, 1936. They were assigned to the depot of their home station in Bratislava and operated under the trade name of "Slovenska Strela" on the Prague – Brno – Bratislava route, with an average cruising speed of 92 km/h (steam trains at that time averaged 68 km/h). The coach was the first with compulsory seat reservation for the ČSD. The travel time was 4 hours and 51 minutes, including a stop-over in Brno, which lasted 35 minutes.
After World War II, the coaches were used for government purposes. The M 290.001 was retired in 1953. In the beginning of the 60’s, it burned out and was scrapped.
The M 290.002 was in government service until 1960, when it was handed over to the company museum of Tatra in Koprivnice. Now a full restoration of the coach, with the goal of reaching a fully functional state, is under way in Hranice.
As we said in the last video, a sample of the original 3x3 cm upholstery was discovered on the driver's seat in the upholstery overlay! Thanks to this discovery, we were able to ensure the production of a almost identical material as it was in Slovenská Strela in 1936. And now you can watch a video of how the seats were installed in the interior of the Slovenská Strela.

V pondělí 25.5.2020 nastane další významný milník v projektu restaurování motorového vozu M 290.002 "Slovenská strela". Vůz bude přepravován z areálu ČMŽO-elektronika v Hranicích na Moravě do areálu mateřské firmy ČMŽO v Přerově, kde bude v nové moderní lakovně opatřen finálním nátěrem. Unikátnost přepravy spočívá v tom, že pod vůz byly zavázány původní zrestaurované podvozky a do Přerova tak bude přepravován po vlastních kolech. Po šedesáti letech se tak Slovenská strela vrací na naše koleje, byť zatím ještě nemůže jet vlastní silou.
Plánovaný čas odjezdu z Hranic je ve 14 hodin. V případě silných přeháněk se přesun uskuteční v úterý 26.5.2020 ve stejném čase.
Děkujeme regionalnitelevize.cz za krásnou reportáž o elektromotorech Slovenské strely. Nemůžeme se dočkat na to až budou motory přichystané v našich dílnách na montáž do podvozků. Kdo by řekl, že už to je rok a půl od doby co jsme Slovenskou strelu začali renovovat.
It's been a year since the company Macháč Motors s.r.o. took over the gasoline engines of Slovenské Strely. As you can see in the video, the first engine runs like a clockwork. The second engine is waiting for parts to be delivered and will be in functional state in the upcoming days. We thank the whole team for their excellent work.
Question: Regarding the image with ballast weights on the floor, I would like to ask you why the weights were there. Was this by chance a test of the vehicle body rigidity?
Answer: Those weights actually simulated the weight of the interior equipment + passengers during the carriage body rigidity test.
Question: Regarding the second image, what material was used for filling the carriage walls? It looks like foil.
Answer: With regard to minimizing the weight of the carriage, the wall filling was made of a four-layer aluminum foil. In those times it was called "alfol" and it was thermal insulation. The leaves were inserted loosely inside the frame, with plain threads securing them.
