Rolling stock

Market characteristics

The railway world is characterized by a tough and uncompromising working environment.
Constant shock & vibration, dust, temperature and humidity variations and electric disturbances mean that components must work under harsh conditions. This puts heavy demands on their reliability. This is the world in which Mors Smitt has invested best efforts, parts and components that work unquestioningly, offer a long effective life and result in low lifecycle cost.

Railway directives

Our products are designed and compliant to the strictest railway directives, such as EN 50155 Electronic equipment used on rolling stock for railway applications, IEC 60571 Electronic equipment used on railway vehicles, and EN 50463 Energy measurement on board trains.
  • CATenergy Energy and Traction control

    CATenergy Energy and Traction control

    The international railway markets demand focus on minimizing carbon footprints. Diminishing natural resources, raising energy costs, protection of the environment, de-regulation of train network traffic requires responsible and pro-active developments in the railway business. At the same time new trains require more integrated solutions to simplify the design, to save place and weight. Since several years, the metering on board is the essential step to go forward with Energy Efficiency…
  • Circuit Protection

    Circuit Protection

    Mors Smitt offers a wide range of railway hydraulic magnetic circuit breakers. The circuit breakers are fully configurable to meet individual requirements. Advantages Precise, temperature stable mechanism, due to hydraulic magnetic technology Overcurrent sensing mechanism reacts only to changes of current No ‘warm-up’ period to slow down its response to overload. No ‘cooldown’ period after overload before it can be reset. Derating considerations due to temperature variations are not normally…

  • Hall effect sensors

    Hall effect sensors

    Application The Mors Smitt transducers are used to measure high currents in rolling stock and track side applications. High currents are converted linear to low power signals. Description The transducers are based on compensating the magnetic field by a closed loop system. The MSA range is used for the measurement of AC and DC currents with high galvanic isolation between the current carrying conductor and output of the sensor. The current…
  • Maintenance & Test Equipment

    Maintenance & Test Equipment

    To minimize Life Cycle Cost of products and systems it is important to perform maintenance at exactly the right moment: not too early when the product has enough remaining lifetime and not too late when the lifetime is over. Mors Smitt offers a comprehensive set of maintenance and test equipment for in-service inspection, fault finding, and verification of relay conditions for optimum Life Cycle Cost.
