Weir-Jones Engineering launched and commercialized its Rockfall™ solution in 2008 for clients around the globe. Our ongoing R&D investments ensure the latest updates are available to every customer. Rockfall™ has been developed in conjunction with Canadian National Railways, CP Rail and Transport Canada.

Rockfall™ is exceptionally versatile and in addition to providing ongoing reliable data for train operators, the system can be used in open pit mining, as a perimeter security system in local or remote sites and in any instance where a concern for falling debris exists.


The Weir-Jones Group has been listening to acoustic transmissions since the early 1970s, and has tens of thousands of channels working reliably, enabling better analysis and response all around the world.
