NIR. One notable vehicle was Mark 2F No. 904, which retained its British Rail livery in service with NIR. By 1997, all Mark 2s had been withdrawn following introduction of the DeDietrich rolling stock on the Enterprise. Today, five of these coaches survive - No.'s 300, 305 and buffet No. 547, all under the ownership of the Railway Preservation Society of Ireland, No. 546, in use in England with West Coast Railways as No. 1800, and No. 911 (See below.) A sixth, No. 901, survived in Dalton, England until July 2012 when it was finally scrapped. From 2001 to 2009, NIR operated a single rake of coaches to supplement the DMU fleet. The total of ten were all built as Mark 2s for British Rail, and were purchased by NIR in three batches: Generator Van – the set has a single generator van converted from a Mark 2 BFK that was purchased and converted in 1981. Passenger coaches – the main part of the set is formed from eight Class 488 unpowered trailers previously operated on the Gatwick Express, which were purchased in 2001. Driving trailer – a DBSO was purchased in 2006 for use with the train to allow a greater degree of flexibility in its use. This was finally delivered in the summer of 2009. From 1998, NIR prefixed their numbers with "8" so as to be part of the Translink number series, which incorporates their road vehicles The table below lists the hauled passenger coaches that were in use until June 2009 plus the never used DBSO (This excludes the "De Dietrich" stock jointly owned with IÉ for operating Enterprise services between Belfast and Dublin. All ten coaches have since been withdrawn from service and sold into preservation. The Generator Van and eight passenger vehicles were acquired by the Railway Preservation Society of Ireland (RPSI) in 2014 with the intention of enhancing its Mark 2 fleet, though in 2022 began disposing of the set. The DBSO has been purchased by the Downpatrick & County Down Railway is used as a barrier vehicle to allow a 146 class locomotive to haul the DCDR's Class 450 DEMU.
