The May 2015 issue of Railway Age magazine features a review of the North American revenue-earning fleet by Dr. David Humphrey, a data scientist at Railinc. This summary of our annual North American Freight Railcar Review features key findings from Humphrey's report, including information about the age and size of the fleet, year-over-year changes in the counts of the six railcar types that make up the revenue-earning fleet and the characteristics of new railcars joining the fleet.

 
You can read more about the state of the revenue-earning fleet in Railinc's North American Freight Railcar Review 2015, which is available to download for free. Humphrey talks about the 2015 railcar review in a Railinc Tracks Blog Q&A, and past years' reports are available to download for free.
