Case Study:

Traction and Auxiliary Power System Support

TTM has been to 'go to' solutions provider for operators when the OEM is not meeting their technical support needs for traction and auxiliary power systems.

Scope of Services, Design & Supply

C2 Series Solidworks


For decades, TTM have offered operators throughout Australia an excellent local alternative for the support of complete power systems. We have a deep understanding of the typical topologies used on all ages of fleets and can therefore often support systems even without documentation.

We are very much aware of the safety critical aspect of these systems and will not compromise in component selection or correct engineering procedures when undertaking these works. This includes full traceability through the procurement process to ensure authentic components are sourced.

We have countless examples of achieving
  • Reduced repair costs
  • Improved lead times
  • Unbiased and detailed insight into the failure modes
  • Technical solutions for reliability upgrades

Some recent examples of these works include the repair, detailed fault diagnosis and/or reliability improvements of

  • Alstom ONIX 800 propulsion system
  • Alstom ONIX 1500 propulsion system
  • Siemens Compact Inverter propulsion system
  • AEG/Siemens SRG II DC Chopper Drive
