Working by the railway?

Third Party Works Procedure

All Third Party Works are to be carried out in accordance with the NIR Third Party Works Procedure. A Third Party is defined; as an external party to NIR who seeks to do work that potentially impacts the railway in any form, works that are adjacent to the railway property boundaries, under, over the railway or have a direct or indirect impact to the infrastructure, operations and safety to the railway. 

A third party, as set out in this procedure, may refer to the third party itself, its agents, consultants, representatives or contractors (including sub-contractors). Working near the railway can be a dangerous environment and we are in a position to help you navigate the risks. Translink (NIR) is committed to safety so we want to help you deliver your works safely and securely.

Additional Important Information

NIR Contractor Safety Requirements

NIR Contractor Safety Requirements apply to third party contracts where a party, other than NIR, engages a Contractor to carry out work on or near NIR Infrastructure.  In such circumstances the third-party client should engage with NIR’s Third Party Works Engineer as early as possible to ensure that the safety requirements are understood and notified to the third-party contractor. The third-party client shall ensure that the NIR Contractor Safety Requirements are included in any contract for works on or near NIR Infrastructure. No works may commence until NIR is assured of this requirement. Once agreed with NIR the Contractor’s Representative may engage directly with NIR’s Third Party Works Engineer in managing compliance with the requirements. 

Safety Critical Competency (Personal Track Safety (PTS) Course)

Personnel who are required to access or work on or near to the railway track are required to complete a Personal Track Safety course. This should be organised well in advance of commencing work as a specific medical and toxicology must be passed before the training can be undertaken. Details of approved medical and training suppliers are provided below.
