Based on a study made by Canadian National Railways in the south main line through the mountains of British Columbia between Jasper and Vancouver, this report discusses how to combat the hazard of rock falls on track in rugged and mountainous territory. The causes of rock instability are briefly reviewed, and the issue of cost versus safety is discussed. Past and present (North American and foreign) approaches to a solution of the problems are noted. The stabilization measures described here include scaling and trimming, rock blasting, design of slopes, drainage, prevention of weathering, and support and restraint systems. Protection measures are also detailed and include track relocation, intercepting ditches on the slopes, shaped ditches, wire mesh blankets, catch nets and fences, catch walls, and rock sheds and tunnels. Warning measures and organization of work (overall policy, program and priorities, records, staff etc.) are discussed.
