In Depot Services

We offer a range of in depot services including visual inspection and fault finding in situ, static testing of equipment and commutator profiling.


With experience of working in train depots around the country, our specialist engineers can test for the following while the traction motor is still connected to the train:

  • Surge on windings
  • DC dielectric strength
  • Insulation resistance (Megger test)
  • Polarisation Index
  • 1,2/50 pulse

Condition monitoring, such as vibration analysis, temperature checks and visual inspections and can also be carried out to identify faults and assist rolling stock engineers in planning maintenance and helping to reduce in service failures.

The benefits include:

  • Reduced in-service failures
  • Improved reliability and life cycle management
  • Identification of vulnerable motors before they fail
  • Data driven failure mode analysis
  • Extends time between overhauls
  • Maintenance can be scheduled more efficiently
  • The services of a dedicated in depot team or an individual engineer on a per shift basis
