Analytical Proof & Invariants
Machine PrecisionGoverning Mathematical Formula:
Intermodal Savings = OTR Trucking Rate - (Drayage Origin + Rail Linehaul + Drayage Destination)
Step-by-Step Mathematical Derivation
1
All-In Intermodal Summation
Intermodal Total = Rail Linehaul ($1,650) + Origin & Destination Drayage ($850) = $2,500.00.
2
Economic Differential
Savings = Direct OTR ($3,200) - Intermodal ($2,500) = $700.00 per 53ft container (21.9% cost reduction).
3
Carbon Emission Analysis
Rail freight is ~3 to 4 times more fuel-efficient than highway trucking, moving 1 ton of freight ~500 miles on a single gallon of fuel. CO₂ reduction = 2.4 metric tons per load.

Frequently Asked Questions
What is the minimum distance where intermodal rail makes financial sense?
Domestic intermodal rail generally requires a minimum lane length of 600 to 750 miles. On shorter lanes, the double drayage costs at both ends negate the rail linehaul cost advantage.
Is intermodal shipping slower than highway trucking?
Yes. Intermodal typically adds 1 to 2 days of transit time compared to solo OTR trucking due to train assembly at classification yards and ramp drayage appointment scheduling.
