Fuel surcharge calculations are required by the Surface Transportation Board ruling STB Ex Parte No. 661. The railroads listed below have chosen PC*MILER Rail Practical miles as their standard for fuel surcharge calculations. All other major railroads chose PC*MILER Rail Shortest miles as the standard.

Therefore, PC*MILER Rail uses Shortest miles by default when Fuel Surcharge routes are generated but uses Practical routing for the railroads listed below. See a full list of railroads in PC*MILER Rail.
