Software Update to BNSF Mileage-Based Fuel Surcharge Calculation Program

Effective Wednesday, March 1, 2017, BNSF will upgrade to PC*Miler Rail version 23.0 as the mileage source for BNSF Local, BNSF portion of Rule 11 and Interline moves on which BNSF has pricing authority. BNSF will use the PC*Miler Rail Fuel Surcharge Router option in version 23.0 to calculate total miles for these moves. This represents a change from PC*Miler Rail Fuel Surcharge Router version 22.2, which BNSF has used since September 1, 2016.

For details about the updates to PC*Miler version 23.0, see the ALK Technologies website.

ALK Technologies is a private software company. Updates to PC*Miler are the exclusive decision of ALK Technologies and are not dictated or controlled by BNSF.

For auditing purposes, version 22.2 mileages will remain available on the BNSF website after the upgrade to version 23.0.

Customers can continue to look up mileage for unit train movements subject to the coal unit train mileage table here.
