Montenegro Vows to Bring the €20 Green Rail Pass to Lisbon and Porto Suburban Trains, Possibly From September

Portugal's flat-rate national train pass could soon carry commuters around Lisbon and Porto as well. Speaking at the Festa do Pontal, the Social Democrats' traditional start-of-season rally in the Algarve, Prime Minister Luís Montenegro said the Passe Ferroviário Verde (Green Rail Pass) — the €20-a-month ticket that already covers most of the country's trains — will be widened to include suburban rail inside the two metropolitan areas, "probably as soon as September."

"Anyone who wants to travel by train within the Lisbon and Porto Metropolitan Areas can also do so for 20 euros a month," Montenegro told the crowd. It was a line delivered from a political stage rather than a formal government decree, and the caveats matter: no start date has been fixed beyond a "probably," and the prime minister named no individual lines. But if it lands, it would close the single biggest gap in a pass that has become one of the government's most popular consumer measures.

What the pass covers today — and what it doesn't

Launched in October 2024, the Green Rail Pass gives unlimited travel for €20 over 30 days (or €40 and €60 for 60 and 90 days) on Comboios de Portugal's Regional and InterRegional services, on second-class Intercidades (with a compulsory seat reservation), and on the Coimbra urban network. It does not cover the premium Alfa Pendular.

The catch for city commuters is the one Montenegro is now promising to fix. The pass deliberately excludes the busy suburban lines inside the Lisbon and Porto areas — the Sintra, Cascais, Azambuja and Sado routes around Lisbon, and the Aveiro, Braga, Guimarães and Marco de Canaveses routes around Porto — because those sections are already served by the regions' own intermodal passes. Only the stretches that run beyond the metropolitan boundary, such as Carregado to Azambuja or Paredes to Marco de Canaveses, are currently included. Extending the €20 pass across the whole suburban network is what would make it genuinely useful for daily commuters in the two cities.

How it collides with Navegante and Andante

The change would overlap directly with the metropolitan season tickets that already exist: the Navegante pass in Lisbon and the Andante pass in Porto, both capped at €40 a month. Those are multi-modal — they cover train, metro and bus across the region — while the Green Rail Pass is rail-only, on CP. So a €20 green pass inside the metro areas would not replace Navegante or Andante for anyone who changes onto the metro or a bus, but it would undercut them sharply for commuters whose journey is train-only, offering the same rail coverage for half the price.

That is the awkward arithmetic ministers will have to resolve, most likely in coordination with the Lisbon and Porto transport authorities that run the intermodal passes and with the infrastructure manager, IP. None of that machinery was spelled out in the announcement.

A popular pass running near capacity

The Green Rail Pass has sold more than a million times since launch, passing the milestone in April 2026 and banking over €20 million for CP; around 70,000 were active in a typical month in early 2026 (a pass sold is not the same as a pass in daily use). Its popularity is also its problem. Infrastructure Minister Miguel Pinto Luz has conceded that capacity "is at its limit," with trains selling out and the fleet stretched. CP has ordered 185 new trains, but they arrive gradually through 2030, so pouring more passengers onto packed suburban services is not without risk.

The move fits a broader ambition the government has floated since the spring: a single nationwide intermodal pass covering train, metro and bus. The September step, if it happens, would be a down payment on that idea rather than the finished article.

What this means for residents

• Lisbon and Porto commuters: If you travel to work by train and stay on the rails, a €20 green pass could halve what a €40 Navegante or Andante costs — but only from a start date that is still just "probably September," and only for CP trains, not the metro or buses.
• If you connect to the metro or bus: Navegante and Andante still make sense, because the green pass does not cover those modes. Check your actual door-to-door journey before switching.
• Nothing changes yet: This is a stated intention from a party rally, not a published rule. Keep your current pass until CP confirms the extension, the lines and the date in writing.
• Expect crowded trains: With the network already near capacity, added demand on the Sintra and Porto suburban lines could mean tighter carriages before the new fleet arrives.

For now, the promise is exactly that — a promise, made from a summer stage. Whether the €20 pass reaches Lisbon and Porto's suburban platforms in September will depend on the detail the government has yet to publish.
