“I’d be in favor of cutting the subsidies of trucking”
What are the “subsidies” to trucking?
Trucks do not pay road tax proportionate to the damage they do to roads compared to cars (and SUVs).
One example (check Google to learn of more): Road construction (especially with such things as the "Stimulus Package") are costs dropped largely on the taxpayer, with trucking user fees far less than the actual cost burden trucks place on the road network. When trucking pays 60% of their burden back into the system, the taxpayers are stuck with the other 40%. That 40% greatly exceeds any rail subsidies.
Also, this (PDF) has some interesting considerations.
