The MÁV series 328 was a passenger train locomotive series of the Hungarian State Railways MÁV, which was developed as the successor series for the MÁV series 327 .

history

The operation of the MÁV series 327 showed its main shortcoming, the short connecting rod and the resulting later cracks in the frame. That is why the engineers at MÁVAG were already working on a machine with a connecting rod up to the second coupling axis after it was commissioned. However, the locomotives with the 328 series were only implemented after the war .

1920–1922 MÁVAG delivered 56 machines of this series. Since this plant could not deliver all the locomotives ordered due to the war, another 83 machines were manufactured by Henschel & Sohn in Cassel . These could still be delivered in 1920.

Their output was 1,350 hp. At 90 km / h, however, it ran restlessly because of its short length. Nevertheless, this locomotive ensured that light inland express train and passenger train services could be transported. They were able to carry 320 t at 90 km / h and 485 t at 75 km / h on the level route. During their deployment, their deployment also moved to Romania and Czechoslovakia.

The machines could keep operating until the end of the steam traction. It was not until dieselization and electrification sealed the end of the locomotives in the 60 years. 1973 is considered the end of the last machine. One, the 328.054, has been preserved in the Budapest Railway Park .

technical features

Due to the war, the locomotives were manufactured with the Brotan boiler . This type of construction was widespread in Hungary and has proven itself here by and large. A new feature on the machine was a smoke consumption system. This system turned out to be inexpensive, but later it was abandoned because the heater had to open and close a valve each time it was fired.

The locomotive was visually strikingly short. The reason was that the running bogie was pulled back to the first coupling axle to achieve an optimal weight distribution. As a result, the guided length was shorter than that of the MÁV series 327 , and the locomotive ran restlessly at top speed. The disadvantage was the narrow and short driver's cab, which did not adequately protect the staff from bad weather.

The 328 series in Czechoslovakia

25 locomotives were transferred to Czechoslovakia and were used there on Slovak territory. The machines were there in their traditional services on the routes supplied. Here the locomotives were taken out of service at the end of the 1950s.
