Rolling stock Current fleet Each push-pull trainset consists of seven coaches and a 201 Class locomotive. The 28 carriages were delivered as four sets of seven but entered service as three sets of eight, with two locomotives from each operator. The coaches were manufactured by De Dietrich Ferroviaire, while the locomotives are from GM-EMD; ownership of the rolling stock is shared between both operators, with carriage maintenance by NIR and locomotives maintained by IE. The coaching stock is based on the Class 373 EMU stock used by Eurostar, with the interiors identical. The EMU stock is articulated and permanently coupled, but the Enterprise is ordinary coaching stock. The service had suffered from a lack of reliability of the locomotives, which provide head end power to the train. Unlike IÉ's Dublin-Cork services, which operate with the locomotive operating with a generator control car that provides power for lighting and heating the train, the Enterprise fleet was only equipped with an ordinary control car, which had no power generating capability. This meant that the locomotive had to provide all the power for the train, both motive and generating. Extended operation in this mode caused damage, so four further locomotives were allocated to Enterprise from the IÉ fleet. However, this still required locomotives to be used in HEP mode, so in May 2009 the Minister for Regional Development in Northern Ireland requested an estimate for the provision of generator functions for the existing rolling stock so that head-end power mode would no longer be needed. In order to avoid further problems, a modified Mark 3 Generator van, formerly 7604, was introduced on Monday 10 September 2012. Three further such generator vans have since entered service. If an Enterprise set is unavailable, either a NIR or an IÉ set can be used. Both NIR and IÉ have equipped six each of their newest DMUs (3000 and 29000) and ten 22000 Class DMUs to each other's specifications so they may be used in the event of a breakdown.
