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


 traction power supply

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
