A subway or metro system is a railway, usually in an urban area, with a high capacity and frequency of service, and grade separation from other traffic. In most parts of the world these systems are known as a "metro", in London the system is called the "Underground", while in most of North America and in Glasgow, Scotland it is a "subway".
