Terre Rocheuse Transit Metro (TRT Metro)

The Terre Rocheuse Transit Metro (TRT Metro; : Métro du Transport Terre Rocheuse) is a system in Terre Rocheuse, covering most settlements and all cités in the country. The first parts of the MRT, Lines 1 and 2, opened on 2 April 1990. The system has now grown to have 5 lines and connections to all cités, airports and ports.

With an average daily ridership of 1.7 million in 2017, TRT is the most popular transport option in Haripure, more popular than the Bus, Tram and RER systems. The metro network encompasses 165.4 kilometres of track, with 168 stations in operation. Each section of the network received major government funding.

History
After the massive financial and population booms followed by the modernisation that happened soon after independence, Terre Rocheuse was having to rely and its overcrowded bus systems and its legacy tram network. The lack of efficient public transport was creating chaos on the road systems and this was hindering the city-state's potential growth. In 1984, the state authorities decided to lay down plans for a 1-line rapid transit line linking the Cité Opale to the Cité Ardal (later separated into 2 distinct lines in 2000). Construction started later that year and the line was opened in September 1990

New extensions and new lines were built gradually through the 1990s and 2000s to bring the network to 4 lines. The long awaited fifth line opened in Summer 2017. A sixth line is planned to link the Cité Azure to the Cité Diamande and the country's airport, expected to open during the 2020s.
