 They have proven to be a very reliable unit despite operating a variety of demanding services including Sligo.They were largely returned to their intended Commuter service since deliveries of 22000 Class DMUs commenced in 2007, which displaced them from Sligo line workings in 2008, though there are still services to and from Rosslare Harbour with the 29000 Class DMUs.However, they remained in their "Commuter" livery when working this long-distance line.
