Barcelona’s Tramway Revolution: Alstom’s APS Technology Enhances Urban Mobility

In a significant leap forward for sustainable urban development, Barcelona has inaugurated a new extension of its tram network, marking the first Spanish deployment of Alstom’s innovative APS (Alimentation Par Sol) catenary-free technology. This cutting-edge system, launched on November 11, 2024, is part of Barcelona’s broader strategy to enhance its public transport infrastructure, making it more eco-friendly, accessible, and equitable.

The Technology Behind APS

Alstom’s APS technology eliminates the need for overhead catenary wires, a common feature in traditional tram systems. Instead, it uses a third conductor rail installed on the track, which is divided into segmented sections that activate and deactivate as the tram passes over them. This not only ensures the safety of pedestrians and road users but also maintains the autonomy of the trams even during extreme weather conditions or unexpected incidents[2].

Impact on Urban Mobility

The new 2km extension, which is part of a larger project to connect Barcelona’s two tram networks, Trambaix and Trambesos, is expected to transport an additional 24,000 passengers daily. This significant increase in capacity is projected to remove around 2,000 cars from the city centre, contributing to a reduction in traffic congestion and air pollution. The extension includes six new stops and will improve mobility by enhancing intramodality with the suburban and metro networks[2].

Urban Transformation

The project is not just about expanding the tram network; it also encompasses a major urban transformation. New cycle lanes, green spaces, and pedestrian areas have been created, enhancing the overall urban landscape and quality of life for residents. This aligns with Barcelona’s commitment to sustainable and equitable urban development, making the city more livable and environmentally friendly[1].

Global Precedent

Alstom’s APS technology is already in use in 11 cities across four continents, including Bordeaux, Tours, Rio de Janeiro, and Sydney. Over 370 trams operate on more than 150km of track using this system, having covered 58 million kilometres as of July 2022. The success of this technology globally underscores its reliability and effectiveness in enhancing urban mobility[2].

Public Transport Excellence

Barcelona’s tramway, which was inaugurated in 2004, is highly regarded for its efficiency and user satisfaction. The network, comprising two independent systems (Trambaix and Trambesos), spans 29.22km with 56 stops and transports over 30 million passengers annually. The adaptation of 18 Citadis trams to the APS system further solidifies Barcelona’s position as a leader in innovative public transport solutions[2].

This latest development in Barcelona’s tram network is a testament to the city’s ongoing efforts to create a more sustainable, accessible, and efficient public transport system, setting a high standard for urban mobility in Europe.
