Bombardier Transportation has won an order from the Electric Urban Train System of Guadalajara, or SITEUR, to supply 12 light rail vehicles, or LRVs, of the TEG-15 model, consisting of two cars each, that will run in Line one of SITEUR in Guadalajara. The contract is valued at approximately MXN 752 million ($44 million, €40 million). The teams of Bombardier Transportation's facility in Ciudad Sahagun, State of Hidalgo, are leading the development of the process, from design and engineering to complete production and putting the vehicles into service.

The 29.56 meters long articulated carbon steel trams will run in pairs and are designed for a maximum capacity of 48 seated passengers and more than 300 standing passengers per vehicle. The new vehicles will be mechanically, electrically and pneumatically compatible with TEG-90 vehicles from SITEUR and will run to a maximum speed of 80 kilometers per hour. The new LRVs' design will be based on the existing fleet of TE-12 vehicles that were previously supplied by Bombardier to the Electric Transport Services of Mexico City (Servicio de Transportes Electricos del Distrito Federal, STEDF) in 2014, with a restyled end bonnet design.

They have proven to be a success with high reliability and low maintenance costs.
