Sound guidance on audible warnings

13 Dec 2022

Revised guidelines on procedures and specifications for testing audible warnings on tramways has been published by the Light Rail Safety and Standards Board.

The document lists the short range and medium range audible warning devices (AWDs) required and details the testing regime needed to ensure their safe use.

Craig O’Brien, LRSSB Head of Engineering Safety and Innovation, explained: “These are essential devices for public safety in typically busy city centres with tramways integrated with general road and pedestrian traffic.

“The guidelines have a vital role to play in helping to protect the general public, passengers and also staff, while also ensuring that the risk of accidental damage to hearing is fully taken into account.”

“The previously issued guidance has been updated with additional information, changes to formatting and other amendments to bring it completely up-to-date.

The guidance document, LRG5 – Tramway Audible Warning Acoustic Test Guidance, is available to download here.

Craig added: “One of the key recommendations in the guidance is that all AWDs should, as a minimum, be checked each time a tram vehicle is handed back from maintenance to be put in operation.”
