The ČSD series EMU 46.0 is an electric multiple unit of the narrow-gauge railway Trenčianska Teplá – Trenčianske Teplice . At the ZSSK , the vehicles were given the designation 411.9.
history
In 1951, three four-axle electric railcars of the EMU 46.0 series were delivered to replace the M 24.0 series . At the same time as the railcars, sidecars that were identical in appearance and dimensions were delivered.
The electric car and the sidecar carried all traffic on their route for decades. They reached up to 35 connections a day.
technical features
The vehicle had four axles.
The appearance of the electric cars was symmetrical. At each tip there was a driver's cab with an entry area. The driver's control panel was arranged in the middle to enable passengers to get on and off without conflicts.
The control was designed in such a way that a controller located under the car body was activated from each control panel, which controlled the electro-pneumatically driven main switch.
The cars had an automatic traction brake controlled by a Knorr driver brake valve. They also had an electrical resistance brake . The railcars were the first vehicles in Czechoslovakia to have a compact automatic coupling .
Technical reconstruction
In 1984 the overhead line voltage on the narrow-gauge railway Trenčianska Teplá – Trenčianske Teplice was switched to 600 V direct current. Therefore, the vehicles were also fundamentally modernized. The designation then changed to EMU 46.1
The renovation was carried out by the workshops in Vrútky . In addition to the changeover to the new voltage system, the vehicles received a new vehicle control system and new drive motors. The pneumatic braking system was converted to the DAKO system . The interior was taken over from the Tatra T6 B5 trams .
Externally, the converted vehicles stand out from the original ones due to the modified window shape. During the renovation, the sidecars were also converted into control cars.
