Metrobús Line 4 Launches Electric Route to AICM

Mexico City has launched a new electric Metrobús service linking Paseo de la Reforma with Mexico City International Airport (AICM), as the capital accelerates its electromobility agenda ahead of the 2026 FIFA World Cup.

Mayor of Mexico City Clara Brugada inaugurated the new Quetzalcóatl route on Metrobús Line 4, which will run from the Glorieta de Amajac in Reforma to AICM Terminals 1 and 2. The expansion adds 19 new electric buses to the corridor, financed through a MX$112 million (US$6.43 million) investment by concessionaires.

“Today, 19 units enter service under the electromobility perspective, which is the direction and the future we want for transportation in Mexico City,” says Brugada.

The route is designed to improve connectivity across strategic zones for residents and visitors, crossing key nodes such as TAPO bus terminal, the Historic Center, Paseo de la Reforma, and Buenavista, while creating a direct connection to the capital’s main airport. City officials frame the project as both a mobility upgrade and a tool to support the city’s tourism, employment, and commercial flows, especially as Mexico City prepares for the World Cup.

Brugada adds that the Metrobús system carries close to 2 million passengers per day, underscoring its role as one of the city’s most important transport networks. She says her administration will continue strengthening the system through additional electromobility projects.

According to Héctor García, Mexico City Minister of Mobility, bringing the 19 electric units into circulation takes Line 4 to 124 buses total, with 74 electric buses now operating on the line. He says the goal is to expand electrification while improving service quality, offering quieter operations and better passenger experience.

Rosario Castro, General Director, Metrobús, says the Line 4 expansion will cover 29km from the Amajac station to the two AICM terminals. The service is expected to operate with a nine-minute frequency, supporting an estimated 3,000 daily trips.

The new buses are designed for dense urban corridors and intermodal demand. They are 8.5m long and have capacity for 70 passengers. They have a projected service life of 15 years and feature onboard fare collection, videovigilance linked to the control center, and monitoring systems.

Officials also highlighted a total of 491 available spaces associated with the service offering, as part of the operational capacity of the new units.

More Projects Tied to World Cup 2026

Brugada says the city will present additional electromobility measures in the coming days as part of a broader package linked to World Cup preparations. She mentions upcoming initiatives including a Centrobús service for the Historic Center, the arrival of new Light Train units to strengthen the Taxqueña-Xochimilco corridor, and modernization of an electric route from Metro Chapultepec to CETRAM Universidad.

In a parallel move to reinforce electric mass transit, Mexico City’s Electric Transport Service (STE) recently confirmed the arrival of two new Light Train trains from Zhuzhou, China. The new articulated units are designed for 292 passengers and include accessibility features, station audio announcements, and onboard surveillance. STE says the broader procurement represents a MX$1.38 billion (US$79.45 million) investment that aims to increase daily demand capacity from 130,000 to 250,000 passengers and expand the Light Train fleet from 20 to 37 units.

The Quetzalcoatl route launch featured participation from transport and industry leaders, including representatives from Sunwin México, Grupo CISA, and AICM management, reflecting the mix of public policy and private investment behind the capital’s electrification push.
