Milan's Metro Expansion Outpaces London and Berlin as European Cities Race to Modernise Transport

Milan's transport ambitions are quietly outstripping those of fellow European capitals. As the city pushes forward with its M4 Metro line extension toward Linate Airport and the broader Passante project, urban planners and transport experts are noting that Italy's industrial heartland is moving faster than London, Berlin, and Paris on comparable infrastructure goals.

The numbers tell a compelling story. Milan's Agenzia delle Entrate has committed €3.8 billion to metro expansion through 2030, with the M4 driverless line already carrying 150,000 passengers daily since its 2022 opening. That velocity contrasts sharply with London's Elizabeth Line, which took 17 years to fully operationalise, and Berlin's perpetually delayed S21 project, now pushed beyond 2030.

"What's remarkable is the political will," says the president of Milano Trasporti, the city's transport authority, who has overseen completion of stations from San Cristoforo through to the city's eastern suburbs. "We're not waiting for perfect funding. We're working in tranches and delivering results."

The contrast becomes visible on the streets. In Porta Garibaldi, regeneration around the new transport hub has accelerated residential investment. Property prices in the neighbourhood rose 12% year-on-year through 2025, compared to stagnation in comparable London neighbourhoods awaiting transport improvements. Berlin's similar Charlottenburg district shows minimal uplift despite decades of transport promises.

Yet Milan isn't without friction. The Passante project—a breakthrough tunnel beneath the city centre linking northeastern suburbs to Malpensa Airport—has generated fierce opposition from residents concerned about vibration and noise near Corso Buenos Aires and the Brera district. Public hearings at the Palazzo Reale revealed tensions between environmental advocates and development backers, echoing similar conflicts in Paris's RER expansion.

Where Milan distinguishes itself is in integration with existing infrastructure. The city is synchronising metro expansion with tram modernisation across 18 lines covering 158 kilometres of track—a network London's Transport for London has actively shrunk. ATM, Milan's transport operator, has ordered 400 new trams by 2028, with 80% funded through EU regional development grants.

Transport experts attribute Milan's momentum to three factors: pragmatic EU funding structures unavailable to post-Brexit Britain, less fragmented governance than Berlin's federal complexity, and lessons learned from the 2015 Expo, which forced infrastructure deadlines and delivered results.

As global cities grapple with climate commitments and congestion, Milan offers a case study in what determined execution looks like. Whether it sustains this pace when projects hit their inevitable complications remains to be seen.
