 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.

The 1.7 kilometres (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 (410.1 ft) at its outer end, no longer reaching Avenida San Fernando.

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. 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 and has never resumed.

 – 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. 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 metre (0.497098189319845 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. 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.
