The ČSD series M 274.0 were four-axle diesel multiple units for regional and express train services of the former Czechoslovak State Railways (ČSD). Because of its color scheme and the elegant, rounded box shape, the railcar was later nicknamed the Blue Arrow .
history
The railcars were developed and built by Škoda in Pilsen between 1934 and 1936 . A total of 14 of these vehicles were produced in three series.
Four-axle Calm sidecars were procured with the railcars , which, apart from the M 274.0, could be used for the M 273.0 and M 275.0 procured at the same time .
With the series production of the M 262.0 railcars , the vehicles were taken out of service. The last railcar was retired in 1959.
M 274.004 has been preserved and was restored to working order using parts of the M 274.002 and M 274.005 . It is based in the Vrútky depot of the MDC Bratislava .
The railcar M 274.003 has been preserved and is being repaired. It is based in the Kutná Hora město train station .
technical features
In terms of structure, the vehicles were similar to the M 262.0 series railcars purchased in large numbers after the Second World War. On one side of the four-axle car body was the drive system with the six-cylinder diesel engine and the electric generator. The electric traction motors were in the bogie on the other side of the car body.
commitment
After delivery, the vehicles initially ran in express and fast passenger train service on the Prague - Most and Prague - Teplice routes . In 1948 all 14 vehicles were present and based in Prague, České Budějovice and Bratislava. Among other things, they operated the “Slovenska strela” express connections between Prague and Bratislava.
