The Canadian Pacific Railway (CPR) was established in 1881 and is now operated by Canadian Pacific Railway Ltd., headquartered in Calgary, Alberta.
The railway was originally built between Eastern Canada and British Columbia between 1881 and 1885, making it the first transcontinental railway in Canada.
The company’s UK offices were at Pall Mall, London and the Royal Liver Building in Liverpool.
