Centreburg Metro

The Centreburg Metro, usually shortened to the Met, is a rapid transit system that is one of the major components of Centreburg's railway network, the other being the Centreburg Commuter Railway Network. It is the country's second-busiest subway system after the Solando Métropolitain, carrying over 1.8 million commuters on a daily basis. Alongside the CCRN, the bus network and the city's ferry system, it is an integral part of the city's public transport system, helping to alleviate congestion and provide a direct link for commuters transiting from the commuter rail network to the city centre.

Opened in 1972 after more than 5 years' of construction work, the network was Corraile's first rail-based transit network to be completely underground, reducing the network's footprint in he crowded city centre, as well as helping to avoid the congestion on the surface that the city's pre-existing tram network had to endure. Today, the system has 87 stations currently in operation and some 101.4 miles (163.2km) of track, and continues to expand with the construction of 3 lines intended the directly connect inner suburban areas to the city centre.
