Intermodal (container on rail with truck drayage at the ends) typically costs 10–25% less than door-to-door trailer on dense long corridors: Manzanillo–Bajío–CDMX, Lázaro Cárdenas–CDMX, and rail crossings to the U.S. The price of savings: 1–3 extra transit days, less flexible windows, and a documentary chain with more actors. The right call is not train or truck by conviction: it is cargo profile, lane by lane.

Profile that wins with intermodal

Regular volume, non-urgent cargo, 700+ km corridors with nearby ramps, and highway-risk goods. Loses: urgencies, rigid retail OTIF, origins far from ramps.

What OCL runs

OCL Cargo is a shipper-side autonomous TMS: agents with computer use build the trip file and reconcile before pay. It can stamp invoice and Carta Porte. Coexists without day-one migration; humans on exceptions. Auditing 100% typically recovers 5–7% (cold chain leakage often sits at 3–5%).

Key takeaways5 points
  1. Intermodal: −10 to −25% on dense long corridors for 1–3 extra days.
  2. Drayage, free days, and split invoices eat the savings.
  3. Winning profile: plannable volume, non-urgent, ramp nearby.
  4. If gap <8%, truck usually wins; >15%, run a rail pilot.
  5. OCL reconciles the full shipment; 5–7%; 6–8 week pilot.
