Csx

CSX Transportation (CSX Corporation) — Two distinct layers. The published layer is tariff mechanics: a rail-mileage-based highway-diesel fuel surcharge schedule effective June 5, 2026 defining the trigger (DOE-EIA monthly US No. 2 Diesel Retail Sales all-sellers average at or above 375 cents/gal), the formula (1 cent per mile per railcar for each 4 cents/gal or portion by which the two-months-prior average exceeds 374.9 cents), the application lag (bills of lading dated on or after the first day of the second following calendar month), and a full tiered cents-per-gallon to cents-per-mile look…

Csx offers (Reference, Price, Supply Chain) — est. the surcharge schedule is trivial in volume — one bracket table of a few dozen rows per publication, with roughly one to four publications per year, so a few KB. The ShipCSX mileage matrix is the substantial asset: the CSX network spans roughly 21,000 route miles with tens of thousands of stations, terminals and interchanges, implying a lane-distance reference on the order of 10^7-10^9 origin-destination pairs served as queries rather than bulk exports. Carload and intermodal movement records at this revenue scale run to hundreds of millions of rows per year..

Rail freight cost modeling for shippers and 3PLs (the surcharge formula plus authoritative rail miles yields the fuel component of any CSXT lane quote); intermodal and truck-rail comparison modeling where fuel escalation formulas differ between modes; contract and joint-rate fuel-escalation benchmarking against competing railroad formulas; inflation and margin analysis decomposing fuel versus linehaul in landed rail cost; hedging work mapping diesel price exposure into freight spend; and the strongest case — the ShipCSX rail-mileage matrix as the authoritative distance reference needed to price or audit any rail or multi-modal lane. Historical surcharge publications also form a clean time series of tariff escalation mechanics across rate cycles.

The data is with 25 years of history.
