Original document, report on the treatment of rock falls on railway lines. Canadian National was created following the end of the First World War, by combining five lines which were financially troubled. It soon became the largest railway in the country. Canadian National Railways was founded in 1919 as a combination of several railways that had become bankrupt and were being ran by the Canadian Government Railways, its primary service was freight but also operated passenger service until 1978 until it was absorbed by VIA rail. The Canadian National Railways was created by the Government of Canada as a means to fund the failing railway corporations including: Intercolonial Railway of Canada, National Transcontinental Railway, Prince Edward Island Railway, and Hudson's Bay Railway.Collection
