Canadian Atlantic

Company History: The CAR was established as a separate “business unit” of CP Rail System in 1988. The goal was for Canadian Atlantic to either find a way to profitably operate the traffic-starved eastern end of the CP Rail System, or failing that, prepare the lines for sale or abandonment. The CAR included the CP Rail routes east of Megantic, Quebec, through the state of Maine and on to St. John in New Brunswick. A segment in New Brunswick was sold in 1994 and became the Windsor & Hantsport Railway. The Canadian Atlantic was officially closed at the end of 1994 and for a brief period in January of 1995 was officially abandoned. However, deals were put in place creating three new railroads: Canadian American Railroad (part of the Iron Road Railways group), Eastern Maine Railway and New Brunswick Southern (both owned by J.D. Irving.)

Successor/Parent History: The Canadian Pacific Railway (CPR), formerly also known as CP Rail (reporting mark CP) between 1968 and 1996, is a historic Canadian Class I railroad incorporated in 1881. The railroad is owned by Canadian Pacific Railway Limited (TSX: CP, NYSE: CP), which began operations as legal owner in a corporate restructuring in 2001.

Headquartered in Calgary, Alberta, it owns approximately 23,000 kilometres (14,000 mi) of track all across Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also serves major cities in the United States, such as Minneapolis, Milwaukee, Detroit, Chicago, and New York City.

The railway was originally built between Eastern Canada and British Columbia between 1881 and 1885 (connecting with Ottawa Valley and Georgian Bay area lines built earlier), fulfilling a promise extended to British Columbia when it entered Confederation in 1871. It was Canada's first transcontinental railway, but currently does not reach the Atlantic coast. Primarily a freight railway, the CPR was for decades the only practical means of long-distance passenger transport in most regions of Canada, and was instrumental in the settlement and development of Western Canada. The CP became one of the largest and most powerful companies in Canada, a position it held as late as 1975. Its primary passenger services were eliminated in 1986, after being assumed by Via Rail Canada in 1978. A beaver was chosen as the railway's logo because it is the national symbol of Canada and was seen as representing the hardworking character of the company.

The company acquired two American lines in 2009: the Dakota, Minnesota and Eastern Railroad and the Iowa, Chicago and Eastern Railroad. The trackage of the ICE was at one time part of CP subsidiary Soo Line and predecessor line The Milwaukee Road. The combined DME/ICE system spanned North Dakota, South Dakota, Minnesota, Wisconsin, Nebraska and Iowa, as well as two short stretches into two other states, which included a line to Kansas City, Missouri, and a line to Chicago, Illinois, and regulatory approval to build a line into the Powder River Basin of Wyoming. It is publicly traded on both the Toronto Stock Exchange and the New York Stock Exchange under the ticker CP. Its U.S. headquarters are in Minneapolis.

After close of markets on November 17, 2015, CP announced an offer to purchase all outstanding shares of Norfolk Southern Railway, at a price in excess of the US$26 billion capitalization of the United States-based railway. If completed, this merger of the second and fourth oldest Class I railroads in North America would have formed the largest single railway company on that continent, reaching from the Pacific coast to the Atlantic coast to the Gulf Coast. The merger effort was abandoned by Canadian Pacific on April 11, 2016, after three offers were rejected by the Norfolk Southern board.
