CIE green livery with a thin lighter green band on the lower panels, giving a uniform appearance to the train sets. In the next change black became the base colour with just a white relief around the top panel, which opened to a squared-off 'V' between the cab windows. Some locomotives received large yellow panel to the cab fronts to aid visibility. With the adaptation by CIE of its "Black and Tan" scheme in the mid-1960s, the locomotives received this livery with a white line at roof level to match the coaches. The last CIE livery was of Golden Brown with a very broad black band covering the upper panels at the level of, and as wide as, the cab windows. Those locomotives sold to NIR carried their blue livery. NIR use After withdrawal from CIÉ, six locomotives were sold to Northern Ireland Railways, which designated them 104 Class. They entered traffic for NIR in 1986–1987, except 105. Originally, CIÉ 224 was intended to become 105, but it was subsequently rejected by NIR and replaced by 218, which only entered traffic in 1991. 224 was left stored with NIR until it was scrapped in January 1996. Of those that entered service, some had very short lives working for their new owners. They were stored as soon as any problems arose (e.g. a seized engine or traction motor), and the whole class was formally withdrawn in 1993 (107/109) or 1995 (the others). The locomotives involved, their new numbers and their withdrawal are set out below: Accidents and incidents On 21 October 1974, locomotive B202 was hauling an empty passenger train when it ran away driverless from Connolly station and collided with a passenger train at , County Meath, A third passenger train, hauled by locomotive B219 was struck by the wrecked trains. Two people were killed and 29 were injured. Preservation Two 201 Class locomotives, numbers 226 and 231, have been preserved by the Irish Traction Group 226 was the first mainline diesel to be preserved in Ireland. C231 is currently based at the Downpatrick and County Down Railway, painted in CIÉ Green livery, whilst 226 is undergoing restoration at Carrick-on-Suir. Irish Traction Group A third example, NIR 106/CIÉ 227 was preserved privately and displayed at Cahirciveen, County Kerry The Irish Crossleys and carries the number C202, which was supposedly the number of the locomotive hauling the last train from Cahirciveen
