China is installing two prototype magnetically levitated (maglev) systems for transporting coal in Inner Mongolia in an attempt to increase transport speeds and efficiencies, and to reduce pollution. Cost studies show $0.13 to 0.017 per ton-mile depending upon the length of magnetic pipe. Rail and truck costs are in the $0.35 to 0.05 per ton-mile cost range.Magplane Magpipes
Magplane Technology designs and fabricates pipeline transport systems using the linear synchronous motor technology developed for the Magplane system. Typical applications for pipeline transport range from priority mail packages to ore transport. A typical ore application would have an underground pair of 60 cm diameter pipes for outbound and returning capsules, and typically carry 10 millions tons per year over a distance of 50 km.

Truck and Rail Freight Statistics Updated
Treehugger reports on the latest efforts to increase the efficiency of rail and truck freight transportation costs.
State-of-the-art trucks can begin to approach the ton-miles per gallon of trains (350+ ton-miles for trucks vs. 400 to 450 ton-miles for rail).
RMI's [Rocky Mountain Institute - energy efficiency evangilists] 2008 peer-reviewed analysis, based on tested science, found a combination of improved aerodynamics, low rolling resisitance tires, and more efficient engines could more than double the ton-mileage of the average class 8 truck from 130 ton-mile per gallon to 275 ton-mile/gallon.
This is mostly theoretical improvements which have not been implemented even in a real life test trial. Walmart has the goal of achieving these level of efficiency gains for its truck fleet by 2015
US Bureau of Transportation Statistics (BTS) show that pipelines move about 20% of the nations freight.
US Bureau of Transportation Statistics (BTS) costs of freight transporation by mode
Air 82 cents per ton mile
Truck 26 cents per ton mile
Rail 2.9 cents per ton mile
Barge 0.72 cents per ton mile (2001)
Pipeline 1.49 cents per ton mile (2001)
RAND study of rail versus truck freight external costs in accidents and pollution. Magnetic pipelines would have lower external costs as well as lower energy costs. Only barges would have lower costs. Barges have more pollution and barges need to have a sufficiently deep waterway to allow for transportation. The magnetic pipeline is faster than a barge.

Energy use by mode of freight transportation according to the CBO (Congressional Budget Office.)
Oil pipelines use only 500 BTUs (British Thermal Units) per ton-mile (280 ton-miles per gallon of diesel fuel), but they are limited by their very specialized function. The efficiency of inland barges (990 BTUs per ton-mile or 140 ton-miles per gallon on average), is likewise offset by the roundaboutness or circuity of most rivers. Also, significant amounts of energy may be required to bring cargo to a waterway system: grain and other farm products are sometimes trucked 200 miles to a river, increasing energy use per ton-mile by 50 percent or more.
The efficiency of rail transportation varies considerably depending on the commodity and the level of service provided; at one extreme, unit trains designed to carry only coal typically require less than 900 BTUs per ton-mile of cargo (155 ton-miles per gallon), while at the other extreme high-speed short trailer-on-flat-car (TOFC) trains use about 2,000 BTUs per ton-mile of cargo (68 ton-miles per gallon).
Intercity trucks require on average about 3,400 BTUs per ton-mile of cargo (41 ton-miles per gallon), twice the rail average and 1.7 times that for rail TOFC. It is not surprising that trucks require more energy since they provide a generally higher level of service than rail.
