"Show me just what Mohammed brought that was new, and there you will find things only evil and inhuman, such as his command to spread by the sword the faith he preached." - Manuel II Palelologus
CN (Canadian National) is one of Canada's two main freight railroads.
Canadian Pacific is the other.
VIA, like Amtrak, is the country's passenger train operator. They own very little physical "railroad". They operate over the various lines of CP and CN for the most part.
