Wednesday 23 July 2008. From Monday 3 November 2008, regular passenger services commenced with this set. On Thursday 17 December 2009, a second refurbished 80 class was deployed onto the Larne Line. The final sets on the Larne Line were 90-749-752-93 and 94-754-747-82. The third refurbished set was stored at York Road and it consisted of 69-733-738-89. It was rumoured that 82 had been withdrawn from service following from an engine fire. 82 was fixed and returned to working order after the fire in Larne. On Tuesday 26 January 2010, 89 entered passenger service with 93, 90 was taken off the set on 23 January 2010. 90 was stored at the south end of the south siding at York Road. Withdrawal from passenger service In 2011, the entire 450 Class fleet, together with the remaining 80 Class units, was listed by NI Railways for disposal. The final 80 Class units were withdrawn from passenger service on Sunday 25 September 2011. Sandite and final withdrawal 97 was converted to a sandite spraying vehicle in 2006 and in 2006 and 2007 was used on these duties coupled to 89. On Wednesday 1 October 2008, 97 had a test run with refurbished 82 and this pair were used for sandite trains until December 2008. In 2009, 97 was on Sandite duties again with 82. During October 2009 while out on sandite duties, the engine in 97 exploded. 82 struggled with hauling dead 97 so it was decided to add 94 to back of the train to help it along. Three Power cars 69+94+90 and two driving trailers 749+752 were overhauled, and in 2012, 97 was painted in all-over yellow to help commuters identify it as a non-passenger train. In 2013, 69, 94 and 752 were repainted into all yellow livery to join 97. As part of this repaint, 69 was accidentally renumbered 96. After the 2014 Sandite season, 94 was taken off the set and replaced with 90, which was never repainted into the Sandite train's yellow sandite livery. It ran as such for 2015, 2016 and 2017 with the final run taking place on Wednesday 22 November 2017. All but one of the Sandite vehicles were preserved. The last remaining 80 Class vehicle in NIR ownership, 97, was scrapped at York Road on 8 June 2019.
