Revenue Ton Miles is a shipping / transportation industry metric, usually reported by train companies, measuring the amount of freight the company transports.
It is calculated by multiplying the weight in tons of the shipment being transported by the number of miles that it is transported. This metric includes only paid tonnage. In other words, only materials being transported for and being paid for by customers.
This metric is used in the Railroad Industry to evaluate the magnitude of company and is similar to the Revenue Passenger Miles metric in the Airline Industry.
