Mercado del Mar is the sixteenth station of the Line 3 of the Sistema de Tren Eléctrico Urbano of Guadalajara from south-east to north-west and the third in the opposite direction.

[1] Before the construction of the station, a monument to Emiliano Zapata (created by Juan José Méndez) was removed from the area; its whereabouts remains unclear.

[3] On June 25, 2018, during the construction of the line, the governor of Jalisco, Aristóteles Sandoval, announced that the station name would be Estación Charros, in honour to the local baseball team Charros de Jalisco, whose home stadium (the Estadio Panamericano de Béisbol) is near the station.

In May 2017, the girders of the steepest curve were being installed in the First Viaduct placed between the Mercado del Mar and Zapopan Centro stations.

At the beginning of the earlier month (April), the Superior Auditor of the Federation (ASF) warned security risks on said curve which measures 105 metres; such failure was compared to the one presented by the Line 12 of the Mexico City Metro, but the Secretariat of Communications and Transport (SCT) cleared that there was no point of comparison between both infrastructures because different materials were employed.
