Mexico City Metro Line 9
Mexico City Metro Line 9 is one of the 12 metro lines built in Mexico City, Mexico. General information. Line 9 was the 8th metro line to be built in the network, built between 1985 and 1988. (Line 8 started operations until 1994). It is identified by the color dark brown, and runs from East to West in an almost straight fashion. It was built in order to support Line 1, providing a redistribution alternative for east-west commuters. It starts in the multi-line transfer station Pantitlán and ends at the western neighborhood of  Tacubaya, both stations also served by Line 1. As a comparison, the section between Pantitlán and Tacubaya is served by 19 stations in Line 1, whereas Line 9 has only 12, which would translate in a faster alternative. Line 9 is built in its easternmost section above the Rio Churubusco and Rio de la Piedad Avenues. Then it reaches an underground route near the Magdalena Mixiuhca Complex and it continues under the Eje 3 Sur until reaching the Tacubaya zone, where the last station is built under Jalisco avenue. As part of the first expansion plans in the 1980s the  line is expected to turn west after Jalisco Avenue to reach Observatorio Station. Rolling stock. Line 8 has had different types of rolling stock throughout the years. As of 2020, out of the 390 trains in the Mexico City Metro network, 29 are in service in Line 9. Proposed extension. Being Tacubaya a provisional terminal, Line 9 had an original project for being expanded to the west to reach Observatorio station as Line 1 did. After the announcement for the Toluca–Mexico City commuter rail, an expansion towards Observatorio station was announced in 2014. As of 2021, the project is  still under planification. Ridership.
