YORK-BASED Jarvis Fastline was a major supplier of track and infrastructure services to Railtrack and Network Rail during the first decade and a half of the privatisation era. It was responsible for the introduction of the innovative ‘Slinger’ sleeper distribution trains and also operated the original Harsco Track Technologies P811S track renewal train.
In order to expand its business, the company decided to enter the coal transportation sector, leasing 94 HYA bogie hoppers from General Electric Rail Services. Built in Romania by IRS (International Railway Systems), they were delivered in 2008 as Nos. 37 70 6791 000-2 to 093-7.
