Understanding NR/L2/OPS/301 — What the Standard Actually Requires

There has been a lot of discussion recently around NR/L2/OPS/301, particularly regarding whether the new requirement for recorded safety-critical communication includes duplex systems. To give the rail industry complete clarity, dBD Communications contacted Network Rail’s Change Lead directly for guidance and their position is clear…

Duplex communication systems are not included within the scope of NR/L2/OPS/301.

The standard — along with the related RAIB recommendation — applies specifically to mobile phone calls between the Controller of Site Safety (COSS) and the Person in Charge (PC). It does not introduce recording requirements for plant-based duplex communication or machine-to-controller workflows.

Where dBD Communications Stand

As the UK’s leading manufacturer and supplier of Network Rail Approved duplex systems, our role remains focused on delivering clear, reliable safety-critical communication for the teams who rely on it every day. Our solutions align fully with current standards, and where recording becomes a requirement for additional roles in the future, our technology is already proven and capable.

dBD Communications has supported recording-ready duplex communication since 2020, but we only activate recording functionality where standards require it. Safety works best when it follows clear, accurate guidance — not assumptions.

If you need help interpreting NR/L2/OPS/301 or understanding how duplex communication fits into compliance, we’re always here to support you. Contact our team for more information:
