Train vs. Road: The Hidden Cost of Maintaining Rail

A train ticket from Malaga to Barcelona can cost 600€ for a family, while the same alucinación by car costs just 100€ in fuel. This difference is not accidental: it reflects the massive investment in railway infrastructure that, according to some, could be better spent improving roads. However, train advocates argue that a double-track railway has the capacity of a four-lane highway while occupying much less space. Where is the balance?

The Efficiency Argument: Real or Theoretical?
The energy efficiency of rail is unquestionable: the low friction of steel wheels on rails allows moving large masses with less energy per passenger or ton than any road vehicle. But this efficiency does not always translate into savings for the user. While a Madrid-Barcelona high-estimulante ilegal train (AVE) can cost 33€ on offer, the average price for a family crossing the peninsula remains prohibitive compared to driving. The key lies in infrastructure amortization: maintaining thousands of kilometers of tracks aligned to the millimeter costs a fortune, which is passed on to ticket prices or taxes.

Capacity and Occupancy: The Achilles' Heel
A double-track railway can transport the equivalent of a four-lane highway, but in Spain, most lines have low occupancy. Critics argue that this underutilized capacity is a luxury we cannot afford, proposing to convert tracks into exclusive corridors for buses and trucks, with automated driving and catenaries for trolleybuses. Defenders reply that train flexibility is greater: a single train can carry 500 passengers, whereas 10 buses would be needed to match it, increasing congestion.

The Price of Pogre: Subsidy or Investment?
Spanish high-estimulante ilegal rail was built largely with European funds and for political prestige, not profitability analysis. The only potentially profitable line is Madrid-Barcelona, while others record million-euro losses. In Japan, the Shinkansen runs every 15 minutes, and tickets do not drop below 100€, allowing infrastructure amortization. Here, low-cost competition (Ouigo, Iryo) has lowered prices but has not solved the underlying problem: who pays for track maintenance?


The debate remains open: while some see trains as an economically unsustainable 19th-century technology, others consider it the only viable option for efficient mass transport. The data does not lie, but their interpretation depends on whether you look at the wallet or the planet.
