GROWING, YET AGING-GRADUALLY

摘要

In Railinc's annual review of the North American locomotive fleet, data showed the fleet continued growing in 2014. Locomotives have long service lives, and their average and median ages both increased in 2014. Locomotives continue to join the fleet at a steady rate-this was the fifth consecutive year of growth. At the end of 2014, the locomotive fleet totaled about 37,400, up about 900 units, or 2.4%, from 2013 (Figure 1).The age of the locomotive fleet increased slightly in 2014. Average and median ages both increased 0.1 years in 2014, the fifth consecutive year this occurred.
