Drug testing for railway workers in the UK

Safety is one of the highest priorities within the UK rail industry. Railway workers are responsible for transporting passengers safely, maintaining tracks and infrastructure, and operating heavy machinery in potentially hazardous environments. Because of this, drug and alcohol testing plays an important role in helping railway companies maintain a safe workplace and comply with industry regulations.

At UK Drug Testing, we supply professional drug and alcohol testing kits suitable for railway companies, contractors, occupational health providers, and workplace testing programmes across the UK.

Why is drug testing important in the railway industry?

Railway employees often work in safety-critical roles where concentration, judgement, reaction times, and coordination are essential. Even small amounts of drugs or alcohol can impair performance and increase the risk of accidents.

Drug testing helps employers to:

  • Improve workplace safety
  • Reduce the risk of accidents and incidents
  • Support compliance with railway industry regulations
  • Protect passengers, staff, and the public
  • Deter substance misuse in the workplace
  • Demonstrate due diligence and responsible management

Safety-critical railway roles can include:

  • Train drivers
  • Signallers
  • Track maintenance workers
  • Engineers
  • Electrical staff
  • Depot workers
  • Contractors working on rail infrastructure

Railway drug testing regulations

In the UK, Network rail updated its Drug & Alcohol Standard (NR/L2/OHS/00120) in 2025 to include a more relevant combination for random testing and stricter medication disclosure requirements.

Railway companies and their contractors in the UK are expected to follow strict health and safety standards. Many organisations follow policies aligned with the Office of Rail and Road (ORR) guidance and industry standards relating to drugs and alcohol in safety-critical work environments.

Drug and alcohol testing may form part of:

  • Pre-employment screening
  • Random drug testing
  • For-cause testing
  • Post-incident testing
  • Return-to-work testing

Many sub-contractors look to operating their own screening programs to ensure compliance during the period of engagement.

Many rail employers and contractors require workers to pass drug and alcohol tests before being allowed on site or issued with certification for rail work.

Network Rail and railway company workplace drug testing

Network Rail's current standard safety critical staff and contractors drug testing panel should includes the following common substances :

  • Cannabis (THC)
  • Cocaine
  • Opiates
  • Amphetamines including Methamphetamine
  • Benzodiazepines
  • Methadone or EDDP
  • MDMA (ecstasy)
  • Tramadol
  • Ketamine

Older RISQS / Network rail aligned providers previously also included Propoxyphene

Alcohol testing is also commonly carried out using a combination of rapid breath and saliva screening and evidential breathalyser confirmation.

Types of drug tests used for railway workers

Urine Drug Tests

Urine drug testing is one of the most widely used methods in workplace drug testing. It is cost-effective, easy to administer, and suitable for detecting recent drug use.

Saliva Drug Tests

Saliva drug testing is increasingly popular for railway workplace testing because it can detect recent drug use and is less invasive than urine testing, and some drug tests can also have a built in alcohol test. Saliva tests are commonly used for roadside and workplace testing programmes.

Laboratory Confirmation Testing

In some cases, instant screening tests will be used, but samples collected will be sent for laboratory confirmation using advanced methods such as LC-MS/MS testing. Laboratory confirmation provides highly accurate results and should always be obtained before any legal, disciplinary, or occupational health actions are taken.

Random Drug Testing in the Railway Industry

Random testing is commonly used within the rail sector to help maintain a drug-free workplace. Workers may be selected for testing without notice as part of a company drug and alcohol policy.

Random drug testing in the railway industry helps to:

  • Act as a deterrent
  • Promote a culture of safety
  • Identify potential issues early
  • Reduce risks in safety-critical environments

Choosing the right railway drug testing kits

When selecting workplace drug tests for railway workers, employers should consider:

  • Accuracy and reliability
  • Ease of use
  • Detection window
  • Testing environment
  • Number of drugs screened and the combination to cover all Network Rail drug groups required.
  • Whether lab confirmation testing is required (all non negative results should be confirmed with a lab test)

UK Drug Testing supplies a range of workplace drug and alcohol testing kits suitable for railway and transport industry use, including urine drug tests, saliva drug tests, breath alcohol testers, and laboratory confirmation services.
