Despite being built for branch-line stopping services, the Class 142s were mainly used on urban commuter services in and out of cities like Liverpool, Manchester, Sheffield, Leeds and Newcastle, and were seen on longer-distance services of up to three hours including the 1632 Middlesbrough-Carlisle service (nearly 110 miles); they had also been used on services between Blackpool North and Chester via Stockport, which ceased to operate in December 2008. All 79 passed with the Northern franchise to Arriva Rail North in April 2016, and any remaining units transferred to the government-owned operator Northern Trains on 1 March 2020.
