Temi Natlia (also known as Natlia Metro) is a rapid transit system in Lugida. The network comprises a great part of Greater Natlia's rail transit system; others being the Arat Light Rail and the Midan Commuter Railway. It is operated by Triamethe Midan Khr., which also operates several feeder buses within the city. Temi is the Lithian abbreviation of Triamethe Midan, which translates to "Metropolitan Electric Train".
The system's first line began its operation between Natlia and Minachi stations in 1935. The line was built below the surface using the cut-and-cover method. Later in 1940 a new line operated between Cafetmin and Kalos stations which would form the present-day Line 6. The ensuing Imperial rule halted expansion plans for the system throughout the decade. In 1950, the system resumed operations and was renamed as Temi Natlia. Greatly increased demand for the system during the 1950s led to numerous expansion projects, the first of which is the extension of the now-Line 6 forming a loop, followed by the opening of Line 3 and 4 in 1962 and 1964 respectively. Most recently Line 14 was opened in 2010 and operates between Hannaim and Primlen stations.
Temi Natlia in its present form has 290 stations across 14 lines in 424 kilometres (263 mi) of its network track. Of the tracks, all within the Line 6 loop are underground; most of its immediate surroundings are as well, while others are either at-grade, elevated, or a combination thereof – parts of Line 13 from Nashemmie eastwards are at-grade, while Line 4 from Siraflair northwards and the whole of Line 14 are elevated. In 2016 the network carried up to 6.5 million passengers daily and 2.39 billion passengers annually, making it one of world's busiest rapid transit systems.
