Software Update to BNSF Mileage-Based Fuel Surcharge Calculation Program

Effective Tuesday, May 1, 2018, BNSF will upgrade to PC*Miler Rail version 24.0 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 24.0 to calculate total miles for these moves. This represents a change from PC*Miler Rail Fuel Surcharge Router version 23.2, which BNSF has used since November 1, 2017.

For details about the updates to PC*Miler version 24.0, 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 23.2 mileages will remain available on the BNSF website after the upgrade to version 24.0.

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