WCML meaning in General ?

The West Coast Main Line (WCML) is one of the most important railway corridors in the United Kingdom, connecting the major cities of London and Glasgow with branches to Birmingham, Liverpool, Manchester and Edinburgh. It is one of the busiest mixed-traffic railway routes in Europe, carrying a mixture of intercity rail, regional rail, commuter rail and rail freight traffic. The core route of the WCML runs from London to Glasgow for 399 miles (642 km) and was opened from 1837 to 1869. With additional lines deviating to Northampton, Birmingham, Manchester, Liverpool and Edinburgh, this totals a route mileage of 700 miles (1,127 km). The Glasgow–Edinburgh via Carstairs line connects the WCML to Edinburgh, however the main London–Edinburgh route is the East Coast Main Line. Several sections of the WCML form part of the suburban railway systems in London, Coventry, Birmingham, Liverpool, Manchester and Glasgow, with many more smaller commuter stations, as well as providing links to more rural towns.

It is one of the busiest freight routes in Europe, carrying 40% of all UK rail freight traffic. The line is the principal rail freight corridor linking the European mainland (via the Channel Tunnel) through London and South East England to the West Midlands, North West England and Scotland. The line has been declared a strategic European route and designated a priority Trans-European Networks (TENS) route.

Much of the line has a maximum speed of 125 mph (201 km/h), meeting the European Union's definition of an upgraded high-speed line, although only Class 390 Pendolinos and Class 221 Super Voyagers with tilting mechanisms operated by Avanti West Coast travel at that speed. Other traffic is limited to 110 mph (177 km/h).
