The Xochimilco Light Rail (locally known as el Tren Ligero) is a light rail line that serves the southern part of Mexico City. It connects to, but is not considered a part of, the Mexico City Metro. Rather, it is operated by the Servicio de Transportes Eléctricos (STE), the authority that operates Mexico City's electric trolleybus system and formerly operated the municipal electric tram system.

History

The light rail line was built in the 1980s, replacing the original Xochimilco tram line that dated from 1910. Many of Mexico City's tram lines were abandoned in the 1960s and 1970s, and the Xochimilco tramway's section between Avenida Tasqueña and the city centre was replaced by a new metro line in 1970.^[3][4] With tramway closures that took effect in May 1979 the only lines left were routes 53 and 54, running from Tasqueña metro station to Tlalpan and Xochimilco, respectively.^[5] These shared a common routing between Tasqueña and Huipulco, with the Tlalpan service branching off of the main line for only about 2 km to its terminus at Avenida San Fernando, in the historic centre of Tlalpan borough. Both lines ceased operation in September 1984, for rebuilding as light rail. Changes to allow faster operation included replacing the simple tram stops with semi-enclosed estaciones (stations), which were spaced farther apart, fitted with high-level boarding platforms and set up as paid areas, so that all payment of fares would take place before boarding. In between the stations the work included installing new tracks set in concrete; putting fencing along the line's right-of-way and closing some street crossings; and installing overhead catenary designed for higher speeds.^[4][6] The fleet of 1940s PCC streetcars was also replaced by a fleet of new articulated light rail cars built partially using components from the old cars, including their PCC bogies (trucks) and propulsion systems (see Rolling stock, below, for more details).^[4][7]

One of the Moyada-built cars that served the Tren Ligero line from 1986–91, seen at Tasqueña terminal in 1990

The 5.5-kilometre (3.4 mi) section between Tasqueña and Estadio Azteca (Aztec Stadium), just short of Huipulco junction (for the branch to Tlalpan), opened as light rail on 1 August 1986, but ran for only three days before poor reliability with the heavily rebuilt rail cars led to a decision to suspend service.^[6][7] Service resumed in November 1986.^[7] Right-of-way work then shifted to the line's outer section, between Estadio Azteca and Xochimilco, with similar upgrading for higher-speed operation. This section opened on 29 November 1988.^[7] The old tram line 54 had included a long loop through the historic centre of Xochimilco, along narrow city streets, but this was not included in the upgrading to light rail, and was permanently abandoned when closed in 1984.^[4]

The 1.7-kilometre (1.1 mi) branch from Huipulco junction to Tlalpan was also rebuilt, but in a different manner, changed from private right-of-way to street running (without separation from other traffic) in the middle lanes of Calle Ferrocarril (now known as Renato Leduc) and also shortened by about 125 metres (410 ft) at its outer end, no longer reaching Avenida San Fernando. Three high-platform stops were built, one being at the new terminus, which was referred to simply as "Tlalpan" on the rail cars' destination signs. Service to Tlalpan was reintroduced on 13 March 1990, now running only as a one-car shuttle to and from Estadio Azteca, no longer through to Tasqueña.^[8] Patronage was low, and service was discontinued only one year later, in March 1991, after an accident damaged the one car (No. 000) normally assigned to the Tlalpan route.^[4] Service was reinstated on 13 December 1991, as STE began to place new cars into service on the Xochimilco line, but ceased again on 6 October 1992^[4] and has never resumed.

The overhead line voltage was 600 Volts DC until around the end of 1995, when it was raised to 750V.^[9]

Route

The line runs between Metro Tasqueña and the town of Xochimilco, south of Mexico City. It serves the Coyoacán, Tlalpan, and Xochimilco boroughs, giving residents a fast link to the urban south of Mexico City. For the northern stretch of its run, it travels along the central reservation of the Calzada de Tlalpan, as does Metro Line 2 south of Metro San Antonio Abad – for this reason, it is sometimes seen as a continuation of that line, albeit on a more 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.^[4] 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 800 metres (0.5 mi) to a new terminus at the western edge of Delagación 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.^[9] 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.

Rolling stock

The Xochimilco line's rolling stock currently consists of 20 articulated light rail vehicles (LRVs) built by Concarril or Bombardier/Siemens. Each car is about 29 metres (95 ft) long and capable of carrying up to 300 passengers.^[10] These replaced older cars starting 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.^[3] A prototype 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,^[7] these cars were found to be unreliable, even after the refurbishment of six in 1989–91.^[4]

In 1989 STE placed an order with Concarril for 12 all-new LRVs with similar capacity, to the same design as LRVs Concarril had recently supplied to Guadalajara's light rail system. Numbered 017–028, the order's first cars arrived in January 1991 entered service on 6 December 1991,^[4] replacing all of the Moyada cars except on the Tlalpan shuttle service. When Tlalpan service was withdrawn again in October 1992, the Moyada cars were no longer used. However, in 1992–93 three Moyada cars (005, 010 and 016) were again fitted with all-new bodies, now to a design intended to resemble the Concarril cars, this work being undertaken by local firm Sintra S.A.^[4] The three "Sintra" cars, the fleet's last to use PCC-type control systems, were withdrawn in late 1995, and shortly afterward the voltage of the line was raised from 600 V DC to 750V.^[9] The newer cars had already been able to operate at the higher voltage.

Four additional LRVs of the same type as the Concarril units were purchased later, in 1995, numbered 029–032. These were built by Bombardier, which had acquired Concarril in 1992,^[11] but were built in the same factory (in Ciudad Sahagún) and were nearly identical to STE's 12 Concarril cars. Four more cars, numbered 033–036, have since been purchased from Bombardier, and these entered service on the Xochimilco light rail line in September and October 2008, increasing the fleet size to 20 cars.^[2]

Stations

Full STE network as of 2006. Xochimilco light rail is shown in dark blue at the bottom center. Other lines are trolleybus.

• Tasqueña – Terminal. Connects with Metro Line 2 and the city's southern intercity bus station, which serves cities like Acapulco, Cuernavaca, and the entire Republic south of the capital. Its logo is an eclipsing moon / crescent moon.
