The Addition of Ketamine and Tramadol to The Substance Panel

    The safety of Network Rail’s workforce, contractors, the travelling public and our neighbours is Network Rail’s priority.

    As a result of this, we continuously review and improve the way in which we manage safety.

    Following an internal audit and external benchmarking exercise Network Rail has made the decision to incorporate two additional substances into the testing panel: Ketamine and Tramadol

    Network Rail has commenced testing for these substances and would like for all contractors working on our infrastructure to be tested for these substances.

    The date in which we are asking for testing to commence is 4th December 2021.

    Originally, we had asked for testing to commence on 4th September 2021 however due to a delay in the publication of the new drug and alcohol standard this date has been moved to 4th December 2021.

    Testing cannot commence prior to this date for non-Network Rail employees as certificates cannot be uploaded via Sentinel correctly.

    NR/L1/OHS/051 will be updated and merged with NR/L2/OHS00120.

    The new standard will be published shortly and will include the testing of both existing and new substances:

  • Amphetamines
  • Benzodiazepines
  • Cannabis
  • Cocaine
  • MDMA (ecstasy)
  • Methadone
  • Opiates
  • Tramadol
  • Ketamine
  • We will continue to review the substance panel regularly in order for us to remain up to date in substance use trends and will inform you should any future changes be required.

  • Remember it is very important that you inform your line manager if you are prescribed any medication, or if your medication has changed
  • If you have any questions, please do not hesitate to contact
