Canada has one of the largest railway networks in the world. The Transportation Safety Board of Canada (TSB) investigates railway occurrences that take place on federally regulated track anywhere in Canada.

Since the TSB’s creation in 1990, Rail and Pipeline Investigations Branch investigations and Board recommendations have helped lead to numerous safety advancements in Canada and across North America, including: the introduction of safety management systems, better passenger safety and emergency preparedness requirements, more stringent criteria for the operation of trains carrying dangerous goods, in-cab video cameras for controlling locomotives and tougher standards for tank cars carrying flammable liquids.

TSB rail investigators come from a variety of backgrounds in the industry, each possessing significant knowledge in some or many aspects of operations, equipment and maintenance of way. TSB rail investigations touch on a wide variety of subjects, such as operational decision making, risk management, component failure, supervision, metallurgy and track–train dynamics.
