modest scale. The light rail line has 18 stations: two terminals and 16 intermediate stations. Three of these stations were built later than the others; Huipulco, Periférico and Huichapan stations opened in November 1993. The travel time from one end of the line to the other is approximately 37 minutes. Until 1995, the outer terminus was located just beyond Calle Francisco Goitia, at what is now named Francisco Goitia station; it was named "Xochimilco" station originally. In that year, the line was extended east by about to a new terminus at the western edge of Delegación Xochimilco's centre, along a section of former tram line 54, closed in 1984. This new section was opened on 14 September 1995, and the new terminus was named Embarcadero. However, as the new terminus was now located closer to the centre of Xochimilco than was the actual station bearing that name, STE eventually renamed Embarcadero station as "Xochimilco", and the original "Xochimilco" station—now the line's penultimate station—became Francisco Goitia station. However, the partly single-track segment from Francisco Goitia to Xochimilco limited capacity on the line, and so the Xochimilco station was rebuilt to the west and equipped with two tracks and three loading platforms. The old Xochimilco station closed in November 2007 for the start of construction, and the new station opened on 14 December 2008. Rolling stock The Xochimilco line's rolling stock currently consists of 24 articulated light rail vehicles (LRVs) built by Concarril or Bombardier/Siemens, between 1990 and 2014. Each car is about long and capable of carrying up to 300 passengers. The first 16 of these replaced older cars over the period 1991–95. The line's original fleet consisted of semi-new articulated LRVs built by Moyada (Motores y Adaptaciones Automotrices, S.A.), incorporating the bogies (trucks) and some other parts from STE's large fleet of withdrawn 1940s-vintage PCC streetcars. (STE originally intended to rebuild about 20 PCCs for the lines, a project well underway at STE's Tetepilco Depot when the workshop building collapsed during the 1985 Mexico City earthquake, crushing the cars.). The prototype LRV was numbered 000, and the remainder 001-016. The Moyada cars had all-new bodies and were equipped with pantographs instead of trolley poles to collect current from the overhead wires. Unlike the old streetcars/trams, they were also bi-directional, having operating cabs at both ends and doors on both sides. Perhaps because of their vintage running gear or electrical components,
