      80% air humidity and more: Our transmissions run reliably in the push-pull tilting trains that travel through the subtropics of Australia.
      Voith has delivered more than 40,000 transmissions for worldwide rail traffic.
      - 40 °C at over 5000 m above sea level: Voith transmissions demonstrate their insensitivity to cold in rail maintenance vehicles during the upkeep of the Chinese high-speed line to Tibet.
      + 45 °C in the shade: Voith transmissions withstand the highest temperatures in passenger railcars in North African Algeria.

      Drive control

        The electronic control VTDC governs all functions of the turbo transmission and thus contributes to optimum operation. As an integrated drive control, it can also control the cooling system and diesel engine as well as ideally coordinate them with each other.

          A good signal for regional transport –  50 Bom Sinal rail buses are equipped with the reliable DIWARail. The diesel-mechanic transmission was equipped for the first time with a reversing transmission for this purpose.
          China's high-speed rail network is the longest in the world and runs through a wide variety of climate zones. For this reason, the vehicles used to maintain the tracks and overhead lines are equipped with only the most reliable technology – for instance, Voith‘s climatically insensitive and robust T 211 re.4 turbo transmissions.
          ZOS Vrutky relies on dependable Voith Turbo Transmissions. The Slovakian vehicle manufacturer has equipped more than 50 railcars with hydrodynamic RailPacks in which T 211 re.4 + KB190 and T 212 bre turbo transmissions are integrated.
          T 211 re.4 + KB190 turbo transmissions from Voith support the SBB when the going gets tough. These are installed in the tunnel firefighting and rescue vehicles built by Windhoff for the Swiss Federal Railways.
          Free ride for the track with Aebi Schmidt's snow blowers: With cold-insensitive T 312 turbo transmissions on board, the vehicles are used for snow clearance in Norway and Austria.
          The ultra-modern ultrasonic measuring trains, which Matisa designed for the French state railway SNCF, stand for the highest measuring accuracy. Voith supplied T 312 bre turbo transmissions that exactly match the requirements of these special purpose vehicles.
          More than 100 T 312 bre turbo transmissions are used in multiple units of the Turkish State Railways built by a joint venture consisting of Hyundai Rotem and Tüvasas.
          As part of the modernization of 110 two-axle class Y9000 locomotives of the SNCF, Voith delivered L 220 reV2 locomotive transmissions.
          Voith has developed a special transmission for Plasser & Theurer’s novel track bed compressor. The tailor-made L 311 reV2 + KB260 is equipped with 8 auxiliary drives, via which the entire engine power can be used to drive auxiliary machines
          130 diesel-hydraulic multi purpose locomotives of Deutsche Bahn are equipped with L4r4 zseU2 turbo reversing transmissions, for which Voith ensures long-term service.
          For its G 1700 and G 2000 multi-purpose and mainline locomotives sold to various European operators, Vossloh relies on proven Voith technology with the L 620 reU2 transmission. This high-performance locomotive transmission is thus operating all over Europe.
