A 100-year-old railway Mexico hopes will rival the Panama Canal (2023)

Relative Capacity and Role vs Panama Canal

  • Cited figures: rail’s projected capacity is ~10.5% of 2022 Panama Canal cargo; CIIT aims for 33M tons by 2033 vs canal’s 63.2M.
  • Some argue it won’t “steal” traffic so much as add capacity, especially while the canal is constrained.
  • Others note there is already a Panama Canal Railway, but its capacity is far below the canal and expansion money preferentially goes to the waterway.

Rail Operations, Speed, and Throughput

  • Transit time is ~6.5 hours for ~300 km. Some see this as slow; others note freight rarely runs “fast” and that throughput, not latency, is what matters.
  • Rehabilitation is raising freight speeds from ~20 km/h to ~70 km/h, with passenger up to ~80 km/h.
  • Single-track constraints, siding lengths, hills, and signaling all limit consist length and capacity.

Economics, Loading, and Network Design

  • Major concern: loading/unloading dominates time. Large ships can take 3–4 days to turn; moving a single container ship may require dozens of trains.
  • Numbers discussed: ~15,000 containers per ship vs ~400 per train; 7.5 ships/day through canal → hundreds of daily trains for parity, seen as unrealistic.
  • Some see value if ports can sort cargo across multiple onward ships and rail links into the US interior, especially given US port congestion.
  • The Jones Act is criticized as making US coastal redistribution by ship uneconomic, increasing the appeal of Mexican alternatives.

Panama Canal Constraints and Water Management

  • Drought and shared use of lakes for drinking water and locks are seen as structural issues; climate change expected to worsen this.
  • Ideas floated: water-saving basins (already used in the new locks), dams, or pump-based recycling, but pumping uphill is viewed as energy- and cost-intensive and likely underfunded while the canal remains highly profitable.

Security, Cartels, and Insurance

  • Multiple comments question how high-value cargo will be protected across 300 km in cartel-influenced regions.
  • Some argue organized crime avoids disrupting projects important to powerful stakeholders; others counter that Mexico’s security situation makes interference likely.
  • Insurance is debated: some claim insurers will avoid the risk; others note cargo to/from Mexico is already insurable.

Drugs, Cartels, and Long-Term Outlook

  • Broader debate links cartel power to US drug policy.
  • One view: the War on Drugs sustains cartels; another: decriminalization (Oregon example) has its own serious problems without strong treatment infrastructure.
  • Some speculate that as Mexico becomes more central to North American manufacturing, US pressure and investment may eventually curb cartel power, but this is contested and uncertain.
