The new Paris métro

Original Article ↗ Hacker News Discussion ↗

Paris’s massive Grand Paris Express project—adding over 120 miles of track and 68 new stations, many in orbital “ring” lines around the city—is held up as a rare modern example of ambitious, effective urban rail expansion. Commenters contrast its scale, speed, and suburban connectivity with the stagnation and high costs of transit projects in the US, UK, and parts of Canada, and branch into debates over design choices like rubber-tyred trains, airport links, fare systems, and accessibility. While acknowledging Paris’s remaining pain points (confusing ticketing, safety perceptions, uneven cleanliness), many see the project as proof that large, integrated public transport investments are still possible—and transformative—when politically and institutionally prioritized.

Scale and Design of the Grand Paris Express

  • Commenters see the expansion (120+ miles, 68 stations, multiple ring lines) as unusually ambitious and well-structured, especially for suburb–suburb trips.
  • Rings are praised for enabling tangential travel without going through the center, though some note rings can lengthen trips if placed too far out or if transfers are slow.
  • The project is viewed as catching up on long‑neglected suburban connectivity rather than just “making the best even better.”

Comparisons with Other Cities

  • Frequent contrast with US cities: NYC and SF are portrayed as unable to deliver similar projects due to extreme costs, slow timelines, and political dysfunction; Seattle, DC, and Ottawa are cited as cautionary examples.
  • Moscow, Shanghai, Tokyo, and Seoul are referenced as having rapidly expanded or extremely high‑quality systems, though some note these benefit from different political or economic conditions.
  • London’s Overground/Elizabeth Line and various Canadian systems are used as intermediate benchmarks; Ottawa and Toronto are often criticized, Montreal and Vancouver more praised.

Rubber‑Tyred Metro Technology

  • Paris’s rubber‑tyred lines (1,4,6,11,14) spark debate:
    • Pros mentioned: higher acceleration/braking, better gradients, less noise and vibration, smoother ride (e.g., Montreal).
    • Cons: higher maintenance costs, niche ecosystem, heat buildup in tunnels.
  • Some argue the technology remains niche globally; others counter that there are many non‑French deployments (Mexico City, Taipei, Japan, etc.), though often still a minority of networks.

Ticketing, Fares, and Privacy

  • Many criticize Paris for lagging in modern ticketing:
    • Paper t+ tickets, confusing zones, clunky vending machines, limited contactless support, and Android‑only app constraints.
    • Navigo is seen as powerful but historically complex for tourists; zones and special cases (Versailles, airports) are described as opaque.
  • Other systems (London’s Oyster/contactless, NYC OMNY, Singapore’s EMV tap‑in/out) are cited as better models, especially with fare capping.
  • Some defend paper tickets/Navigo anonymity and warn that phone‑based systems enable pervasive tracking.

Airport Connections (RER B, CDG Express)

  • RER B to Charles de Gaulle divides opinion:
    • Criticisms: poor luggage space, crowding with suburban riders, safety concerns, suitcase theft, shared capacity.
    • Defenses: at least it exists compared to many airports with no rail; some trains run semi‑express and have luggage areas.
  • A dedicated CDG Express is mentioned but questioned on cost‑effectiveness and demand, citing Heathrow Express as only lightly used.

Cost, Governance, and Construction Speed

  • Many are struck by ~€36–39B building 120+ miles and 68 stations versus multi‑billion‑per‑mile projects in US cities or the UK’s HS2 cost.
  • Explanations floated:
    • Authoritarian or centralized systems (Russia, China) can push projects faster and cheaper, sometimes at labor/landowner expense.
    • In democracies, regulatory overhead, fragmented agencies, NIMBYism, and differing standards (EN vs IEEE in rail software) add cost and delay.
  • There is pushback that even well‑rated democracies like Spain build faster/cheaper than the US, suggesting US‑specific dysfunction.

Cleanliness, Safety, and User Experience

  • Experiences with Paris Metro vary:
    • Some recent visitors find it much cleaner than in past decades and better than many North American systems.
    • Others still report smell, litter, occasional aggression, and theft—especially on airport lines and in busy hubs.
  • Comparisons:
    • Tokyo, Singapore, and some Chinese systems are widely regarded as cleaner, more punctual, and more orderly; Tokyo is treated as a near‑unbeatable gold standard.
    • NYC is often cited as particularly dirty and decayed; Berlin, Stockholm, Montreal, and some Chinese metros receive positive mentions.

Accessibility, Cars, and Social Equity

  • One side argues expanded metro “practically eliminates” car needs for most, reducing congestion and emissions; cites diverse riders (elderly, disabled, low‑income) using transit where it works well.
  • Critics respond that:
    • Long walks, broken escalators/elevators, and crowded transfers can be punishing for people with mobility issues.
    • Safety concerns and the need to carry goods can make cars preferable for some.
  • A compromise view emerges: strong transit can dramatically reduce car dependence overall, while acknowledging some people will still need cars or taxis.

Broader Cultural and Political Themes

  • Several comments tie transit attitudes to:
    • US car‑centric culture, segregation history, and lobbying by car interests.
    • Different notions of “success” for countries (GDP, shareholder value vs. visible public goods).
  • The Grand Paris Express is widely seen as enviable and potentially inspirational for other cities, even as commenters stress that governance, culture, and cost structures differ greatly.
