Who should attend
This course has been designed for delegates who hold a certificate in Signal Maintenance Testing which is nearing the end of its two year limit.


The delegate will be given the knowledge and skills to continue to carry out Defined SMTH Tests, following and applying the procedures and apprehend the documentation specified in the SMT Handbook for the competencies that they already hold.

This will include all the following core skills:

  • Wire Count
  • Temporary labelling of wires
  • AC and DC Earth Testing
  • Insulation Testing
  • Continuity Testing
  • Cable Function Testing

In addition to this, the delegate may also be re-certified on the following competences assuming he has undertaken the tasks within the last two years:

  • Aspect Testing
  • Points detection and correspondence testing
  • Produce a Maintenance Test Plan
  • Prepare a Method Statement for specific Operational Equivalent Alterations
  • Temporary Diversion of a Cable
  • Provide Release of Controls for one train

Learning approach
This is a re-certification of a competence and is therefore a full day of both theory and practical assessments.

On successful completion of all theory and practical assessments delegates will be issued with an SMTH card which will need to be authorised by the delegate's Manager.

The delegate must hold a valid SMTH card.
