Mi Tren Line 4 (Guadalajara–Tlajomulco Light Rail)

Alignment

Line 4 of Guadalajara’s Mi Tren light rail system runs about 21 km from Tlajomulco Centro in Tlajomulco de Zúñiga northeast to Las Juntas, at the boundary between Guadalajara and San Pedro Tlaquepaque. It runs beside the right-of-way of the Ferromex freight line. The stations, from south to north, are Tlajomulco Centro, CUTLAJO, Lomas del Sur, El Cuervo, Concepción del Valle, Real del Valle, Jalisco 200 Años, Acueducto (also listed as Acueducto Solís), and Las Juntas. Before opening, the state said Acueducto might not be finished in time, and SITEUR described an eight-station line at launch.

At Jalisco 200 Años the line connects with the Mi Macro Periférico bus rapid transit line, and a connection with Mi Macro Calzada at Las Juntas was planned as a second phase. Twelve electric trains, each carrying up to 300 passengers, run the full line in about 38 minutes, every 9 minutes, and five feeder bus routes serve the stations. The state government of Jalisco developed the line as a public-private partnership with Mota-Engil, with federal funding, and the state agency SITEUR operates it.
