Thinking in control & monitoring

Control systems for diesel-electric and diesel-hydraulic locomotive of REGULATEURS EUROPA are characterised by precise speed governing and stable and reliable operation. Their compact and robustly designed hardware components are adapted to the harsh environmental conditions in locomotives. HEINZMANN locomotive control systems are installed worldwide, in both passenger and freight trains, and have been chosen by leading locomotive manufacturer for retrofitting.

Viking Traction Control

The Viking Traction Control unit is designed for the railway environment and houses the following main components:

  • Viking Digital Controller ECU
  • Speed switch pcb
  • Protection module
  • Interface circuitry

The engine protection provided by Viking Traction solutions provides de-rating with respect to measured parameters; this helps to ensure that the locomotive can continue to operate safely even if a fault is detected. As an additional feature Viking traction can interface with remote monitoring; thus, allowing operational problems to be viewed and diagnosed at the depot.

Viking Control Panel

Viking Control Panel Traction control panel with Viking35 ECU, performing the following core functionality:

  • Speed governing
  • Start interlocks
  • Engine auxiliaries control during starting/running/stopping conditions
  • 1st and 2nd stage engine protection
  • Overspeed protection
  • Independent engine shutdown by separate protection module


Power Unit

Provides regulated 28 VDC, 300 W power supply output for the traction control and monitoring units, derived from a power car supply input.

Protects components from power supply surges and transients in accordance with RIA12 requirements Includes a back up battery for short periods of loss of main power.

RE 2221-1G

The 2221 is a proportional actuator where the position of the output shaft is proportional to the electrical input signal 0-1 A. This actuator is typically used in medium/high-speed diesel engines in generator systems or locomotives.

Technical data

  • Output range ft lbf: 8, 12, 15, 25, 34
  • Output range Nm: 11, 16, 20, 34, 46, 54
