A proactive rail safety device that detects obstacles and track damage just in time to prevent disasters
Canada suffered from 10 main-track and 527 non-main rail track derailments in 2016 alone. 13% of these derailments involved dangerous goods.
Canada carries over 300 billion tonne-kilometres per year, which represents 68% of Canadian freight. Canada is among the heighest in the world of rail tonnage carried per capita and percentage of frieght carried by rail.

A CN unit train transporting 100 tank cars loaded with petroleum products derailed. It was travelling at 38 mph, below the 40 mph speed limit in place at the time. Twenty-nine tank cars of petroleum crude oil derailed and 19 of these breached, releasing 1.7 million litres of product. The crude oil ignited, resulting in fires that burned for 5 days.
The investigation found that the derailment occurred when joint bars in the track failed. Pre-existing fatigue cracks in the joint bars at this location had gone unnoticed in previous inspections. Once the fatigue cracks reached a critical size, the combination of the cold temperatures (-31 °C) and repetitive impacts from train wheels passing over the joint caused the joint bars to fail. These defects went undetected as the training, on-the-job mentoring, and supervisory support that an assistant track supervisor received was insufficient.More Info
Upon detection of a hazard, the unit will alert the train within a safe distance for engineers to stop, evaluate the risk, perform applicable repairs, and safely pass over or avoid the problem track
