Electric unit 425.95

The electric unit 425.95 is designed for transport of passengers by mountain railways of the High Tatras Electric Railways.

It is a vehicle of similar type as those used in the Alps in Switzerland, with approximately the same profile of line as in the High Tatras.

It is manufactured for Železnice Slovenskej republiky (Railways of Slovak Republic) by ŽOS Vrútky a.s., as a head of consortium, together with their consortium partners, Stadler Fahrzeuge AG and Daimler Chrysler Rail Systems.

In its construction design the electric unit 425.95 meets all requirements for public train transport. It consist of three parts: two end aluminium carriages for passengers and a middle steel driving part through which passenger may cross. The floor of the carriages for passengers in getting-in and gettingoff areas is on the same level as that of platforms. Entrance doors with two wings – are controlled electropneumatically. Inside the carriages for passengers are installed bicycle and ski holders, as well as racks for other kind of luggage. In the modern carriage interior there are 88 seats, 20 tip-up seats and a standing room for 92 passengers. Large windows with tinted glass offer good view of surrounding country. The unit is equipped with electronic information system informing passengers about the next stop/station as well as further railway connections visually and in sound. The construction of the transit middle part minimizes noise and vibration overload.
The unit is equipped with four brake systems:
  1. Electrodynamic brake – controlled by microprocessors, with action in driving axles
  2. Electropneumatic brake – mechanical brake with action in all axles
  3. Spring brake – parking brake with action in all axles – replacing hand mechanical brake
  4. Electromagnetic track brake – with the function of safety brake placed at each side of the vehicle, between the driving axles of its middle part – can be switched on or put to action using express brake.

High construction variability of units of this type gives possibilities to use them not only in mountain railways but also in public transport to outskirts. Module design enables to adjust its transporting capacity according to a client’s demands.
Universal construction design of the driving unit (middle part) – electric traction with the alternating voltages of 25 kV 50 Hz and 15 kV 16 2/3 Hz, unidirectional voltage from 1000 V up to 3000 V, Diesel-electric driving set – provides possibilities for its use in various types of railway with the gauge of 1000 mm or 1435 mm. All workplaces are controlled in compliance with the quality management system according to standards ISO 9001:2000 and environmental management system according to standards 14001:2004.
