This month Railway Age again features freight equipment data and analysis from Railinc. But this time, we take a look at locomotives. Beginning on page 35 of the magazine’s July 2016 issue, Railinc data scientist Dr. David Humphrey gives a summary of the North American freight locomotive fleet’s size and composition.

The article is based on key findings from Railinc’s 2016 Locomotive Review. The review features data related to the characteristics of the locomotive fleet, including information about the age and size of the fleet, new locomotives joining the fleet, types of power in the fleet, horsepower ratings trends in the fleet and more.

Humphrey compiled all the data in the report from Railinc’s Umler® system. The Umler equipment registry contains the physical characteristics, transportation management and pool assignments of more than 2 million pieces of rail equipment in North America. It is the base file for other industry reference files and industry equipment accounting files and is updated more than 600,000 times each month.

The 2016 Locomotive Review provides more detail about the state of the fleet and is available to download for free. You can also read a Q&A with Humphrey on the locomotive and railcar fleets. All of Railinc’s reports—including the 2016 North American Freight Railcar Review—are available to download for free on Railinc’s Research Reports page.
