Contracting to Queensland Rail

Queensland Rail Supplier Code of Conduct

Queensland Rail's goal is to provide a customer focused, safe, reliable, on-time and value for money rail service that benefits the community, supports industry and is integrated with the public transport system. We recognise our suppliers play a pivotal role in the achievements of these outcomes.

Our Supplier Code of Conduct ( PDF | DOCX ) sets out the expectations that Queensland Rail has of its existing and future suppliers.

Important Safety and Environment considerations

At Queensland Rail, Safety Comes First, Always.  Everything we do is underpinned by our commitment to safety.

Queensland Rail has made changes to our Contractor Safety and Environment Management Process to improve how we manage this important component of how we strive to deliver our vision to connect communities through a modern, world-class rail service. Key changes include:

  • The classification of works and/or services based on risk for which contractors will need to be prequalified (for safety and environment) at that level (or higher), 
  • Revised monthly reporting requirements to enhance the visibility and management of safety, 
  • Changes to how we authorise contractor works to commence to ensure safety and environment requirements have been met prior to the commencement of work.

These changes do not affect current contracts with vendors to supply goods or materials or who are contracted to perform works and/or services on their own premises.

Safety and Environment Prequalification

Contractors who will be engaged to perform works and/or services on Queensland Rail owned or leased property that are categorised at Category 1, 2 or 3 will need to successfully complete Safety and Environment Prequalification.

The four categories of works and/or services are:

  • Category 1 – Construction projects that cost $250,000 or more and Queensland Rail appoints the contractor as Principal Contractor.
  • Category 2 – Field based work performed by contractor working under their own Safety & Environment plan.  Queensland Rail has ongoing duties under rail safety and electrical entity elements of the Queensland Rail SEMS.
  • Category 3 – Field based work performed by contractor working under Queensland Rail SEMS and supervision.
  • Category 4 –Work that is administrative or advisory in nature performed under Queensland Rail SEMS and supervision in an office based or field-based environment.

Safety and Environment Prequalification involves a desktop level assessment of your Safety and Environment processes to meet Queensland Rail minimum expectations.

While the prequalification process shall be prompted prior to release of tender documents, Queensland Rail strongly encourages contractors to commence prequalification at your earliest convenience to ensure you are eligible for upcoming tenders.

The prequalification process will involve the following steps:

  1. Register your interest by emailing and outline the types of works and services you provide, nominated contact details for the person in your company and if currently working with Queensland Rail the name of your Queensland Rail contact person.

  2. A Queensland Rail staff member will contact you to discuss and confirm the appropriate level of Safety and Environment Prequalification for your circumstances and provide you with the necessary requirements.

  3. You will complete the Safety and Environment Prequalification Questionnaire and submit with all the necessary supporting documentation to .

  4. Your application will be assessed, and you may be contacted by the Assessor to clarify your responses or request additional information to complete the process.  You will be advised of your outcome and when successful you will be issued with a Certificate which you can use in future tendering activities to demonstrate your success in meeting our Safety and Environment Prequalification requirements.

Authority to mobilise work

Prior to a contractor being granted authorisation to mobilise and commence work at Queensland Rail locations an 'Authority to Mobilise Form' must be completed. Your Queensland Rail representative will coordinate this activity to ensure its completion prior to mobilisation and commencement of work.

The key elements of this activity include:

  • Risk documentation
  • Safety and Environment documentation
  • Location specific requirements
  • Competency verification
  • Induction verification
  • Mobile Plant, tools, equipment and hazardous material
  • Capacity to manage any subcontractors.

Safety and Environment reporting

Contractors who are working for Queensland Rail will be expected to produce a monthly Safety and Environment Report and submit this their nominated Queensland Rail representative by close of business of the 3rd working day of each month.


Category 1, 2 and 3 contractor workers will be required to complete an online Contractor General Induction from 1 January 2020 and every two years thereafter. More information will be provided to contractors, including the sourcing platform in the lead up to this date, interim provisions are in place for induction which will be directed to you by your Queensland Rail Representative.

Verification of competencies

Contractors who provide mobile plant operators as part of the contracting service will be required to submit evidence that these operators have been deemed competent to operate relevant plant and machinery. This evidence of competency is to be supplied to your Queensland Rail Representative prior to mobilisation on site.

Network Lockout - 'No lock, no work in the Danger Zone'

All workers who will entering the Danger Zone when completing work within Queensland Rail's rail corridor will be required to comply with the Queensland Rail Network Lockout Implementation. From  3rd August 2020, the simple application of Network Lockout will become mandatory. Complex applications will continue to be trialled. 

Simple and Complex Applications

Simple application of Network Lockout is defined as all activities that require workers to lock onto one Lockbox only. This applies when working under the following Work on Track Authorities or Means of Protection: Absolute Signal Block (ASB), / Electronic Authority System Blocking (EASB), Track Occupancy Authority (TOA), Track Work Authority (TWA), or Lookout Working.  

Complex application of Network Lockout is defined as all activities that require workers to lock onto more than one lockbox and/or incorporates on track vehicles, track machines, work trains and their movements through a worksite. Complex application also includes any work conducted under a Local Possession Authority (LPA) or the use of a Multiple Workgroup Register.

Note: If a risk assessment determines that a complex application of Network Lockout is required do not implement Network Lockout unless it is specifically planned as part of the Stage 2 Trial. 

Implementation of Network Lockout Simple Application and Complex Application

From 3rd August 2020, Network Lockout will be mandatory for all works which require the simple application of Network Lockout. 

Trials remain ongoing for complex application of Network Lockout. All work scenarios within the complex application trial will be planned in consultation with the Network Lockout Project Team and additional equipment will be provided as required. 

Training requirements to implement Network lockout:

Everyone who is working in the danger zone using Network Lockout must complete the following training; Network Lockout Online workshop which can be accessed here  and complete MD-20-65 Network Lockout Online Training Assessment as proof of competence.

A copy of these forms must be kept by the Contractor as evidence of competence for each individual on site. Additionally, a competency matrix must be maintained as a record of compliance.

Each contractor who is not working within a Queensland Rail workgroup (e.g. Third Parties, Principal Contractors) must confirm with their Queensland Rail Representative who is to be their contact and authoriser in the case of forcible lock removal. This person's contact details must be communicated to the contractor’s Persons in Charge of Workgroups.  

Contractors are to ensure that there is sufficient equipment and trained personnel on site to allow for workers to implement the Network Lockout process completely and effectively.

Specific details about Network Lockout, including detailed definitions of simple/complex applications, equipment specification and the process for the forcible removal of locks, can be found in Network Lockout Procedure MD-19-337.
