Why don't EU countries invest in mutual train lines to reduce CO2 emissions?
EU cross-border rail stalls because each member state pays now and waits decades to benefit, while no corridor-level institution enforces shared commitments.
Schmidt locates the core failure in 1978: states calculate national cost before collective gain, and only move when someone names what they lose by staying out. Keynes adds that private capital will never hold a 30-year payback; the EU must finance corridors the way it financed post-war reconstruction, borrowing now and collecting returns in growth and avoided carbon costs later. Hirschman points to Lyon-Turin: once enough concrete is poured, stopping costs more than finishing, but a tunnel without upgraded approaches on both sides creates a bottleneck, not a route.
Hayek and Ostrom split on the fix. Hayek argues open track access and competitive pricing would shift freight without Brussels mandates. Ostrom counters that the Rhine-Alpine corridor's joint management body already outperforms top-down rules; the answer is corridor-specific institutions with real enforcement power, not a single Brussels committee and not deregulation alone.
Confidence summary: Strong convergence on diagnosis; meaningful split on institutional remedy, reflecting genuine uncertainty about whether market liberalisation or corridor-level governance is the more powerful lever.
1. The core argument
The sharpest insight here is not that cross-border rail is expensive. It is that the cost structure is almost perfectly designed to defeat democratic politics. A minister who commits to a tunnel will never hold office when it opens. A minister who blocks it saves this year's budget. With freight modal share stuck at 18 percent against a 2030 target of 30 percent, and the Lyon-Turin tunnel still a decade from completion after political agreement spanning two generations, this is not a financing failure dressed up as a governance failure, or vice versa. It is both, and they reinforce each other. Private capital discounts the future too steeply to bridge a 30-year payback; public capital fragments across national budgets that face no corridor-level accountability; and the TEN-T regulation, however revised, assigns mandates without assigning enforcers. The council converges on that triple diagnosis. Where it splits is on cure: competitive markets, public deficit-finance, or corridor-specific institutions with real teeth.
2. How each member frames it
Helmut Schmidt reaches for the moment in 1978 when monetary cooperation finally moved: Bremen, a narrow window, two years of bilateral persuasion, and the argument that dollar volatility was costing exporters more than any shared mechanism would. His point is that the political framing of rail must replicate that logic. Each corridor has to be sold to each capital as a sovereignty instrument, meaning the thing that protects your export economy from the road congestion and carbon costs your neighbour's underinvestment creates. The card version stops there. What it omits is Schmidt's harder admission: the framing only works when someone names the defector publicly. Bremen succeeded partly because the cost of staying out became visible. Rail needs the same naming mechanism built into corridor governance.
John Maynard Keynes focuses on what Schmidt's diplomatic framing cannot solve on its own: even a perfectly persuaded finance minister cannot authorise a 30-year bond on a project with no domestic constituency. At Bretton Woods, Keynes argued that long-horizon public goods require institutional architecture to hold the financing across political cycles. His position here is that the EU must treat corridor investment the way it treated post-war reconstruction: borrow collectively now, collect returns in growth and avoided carbon costs over decades. The limit his card cannot fit is his own: Keynes would accept that collective borrowing requires collective enforcement of the spending, and he would not pretend Brussels currently has that enforcement mechanism.
Friedrich Hayek reframes the entire question. The 18 percent modal share is not evidence of too little planning; on his reading, it is evidence that road haulage responds to shipper needs faster than regulated rail can. His argument for open track access and the removal of cabotage restrictions is not anti-infrastructure; it is anti-mandated-map. The counterintuitive element his card omits is that Hayek would not oppose a tunnel per se, only the assumption that a Brussels committee can rank which tunnels serve travellers. Competitive pricing signals would reveal which corridors actually carry demand, and capital, public or private, would follow.
Albert O. Hirschman introduces the hiding hand as mechanism, not metaphor. His fieldwork showed that project designers routinely underestimate difficulty and overestimate their capacity to handle it, and that this is sometimes beneficial because it gets projects started that accurate forecasting would have killed. Lyon-Turin is a case in point, on his argument. The danger he identifies, which the card had to compress, is not irreversibility itself but disconnected linkage investment. A completed tunnel feeding into unupgraded national approaches is a bottleneck built at enormous cost. His prescription is to write the connecting investments into the original contract so that irreversibility works in the whole corridor's favour.
Elinor Ostrom provides the institutional grammar the other members lack. Her comparative work on irrigation commons, Swiss alpine meadows, and Philippine fisheries found that what fails is not collective action per se but governance that separates jurisdiction from the shared resource. The TEN-T regulation sets targets without assigning a corridor-level body with authority to sanction defection. Her prescription, replicating the Rhine-Alpine management structure rather than replacing it with a single Brussels mandate or leaving it to markets, is the most operationally specific position on the council.
3. Where the council agrees
The most surprising point of agreement is that the funding gap is a symptom, not the root cause. Every member, including Hayek, accepts that the current structure produces systematic underinvestment; they disagree about why, but none argues the outcome is efficient. Beyond that, all five agree that multi-decade payback horizons defeat standard public finance cycles, that national budget windows are too short to hold corridor commitments without external pressure, and that the Lyon-Turin case is instructive precisely because political agreement was achieved and construction still took generations. Schmidt and Ostrom converge, from very different directions, on the same practical finding: institutions that make defection visible and costly are necessary. That agreement is not trivial; it rules out pure market liberalisation and pure top-down mandates as sufficient solutions, and it narrows the design space considerably.
4. Where the council splits
The real line runs between Hayek and the rest, though the gap between Hayek and Ostrom is narrower than it appears. Hayek holds that competitive track access and pricing reform would shift freight without Brussels mandates. Ostrom holds that even liberalised markets require corridor-level governance to monitor shared infrastructure and sanction free-riding. Schmidt and Keynes sit on Ostrom's side but for different reasons: Schmidt because political framing requires an institution to carry it, Keynes because deficit-finance requires an institution to authorise and enforce it. Hirschman's position is the most agnostic: his hiding hand works under either regime, provided linkage investments are contractually bound from the start. Neither Hayek nor Ostrom is wrong; the dispute is about which bottleneck binds first.
5. For a policymaker to decide on
The council cannot resolve this: should new EU corridor funding be conditioned on member states accepting a Rhine-Alpine-style joint management body with real enforcement authority, or should it instead be released in exchange for domestic track-access liberalisation? The first option builds institutional accountability but risks bureaucratic capture; the second option signals competitive efficiency but leaves free-rider monitoring unsolved. The choice depends on which failure, governance defection or market restriction, the policymaker believes is binding in their specific corridor.
