Transit
Door-ready adds half the gap between departures — the average wait if your cargo becomes ready at a random moment. On a 10-a-week service that is 0.4 days, and it is the figure a road-versus-rail comparison usually leaves out.
Legs and handovers
A single through leg — no gauge break and no operator handover en route.
- 1 Dallas Alliance → Mexico City PantacoCPKC · Standard (1435 mm) · 1,900 km · 4 d
Track gauge and borders
The spacing between the rails — whether the wheels can run through, or the load has to change trains.
- Countries crossed
- US → MX
- Gauge changes
- None — through running
- Origin gauge
- Standard (1435 mm)
- Destination gauge
- Standard (1435 mm)
Loading gauge clearance
The height and width of tunnels and bridges — whether the load fits through. A different constraint from track gauge above: this corridor can have no gauge break at all and still refuse a high-cube container.
Set by MX, the narrowest network on the route. One restrictive tunnel anywhere caps the whole journey regardless of how generous the rest is. Universal across the continental network. Single-stack intermodal.
- 40ft standard (8'6") on a container flat
- Clears +978 mm
- High-cube (9'6") on a container flat
- Clears +673 mm
- Swap body on a container flat
- Clears +899 mm
- P400 semi-trailer on a pocket wagon
- Clears +454 mm
Profiles are the published maxima for each network's core freight routes. Individual lines differ in both directions, so a load within 50 mm of the limit needs the operator to confirm the specific path. Compare wagon deck heights →
