In 2014, a mid-life refurbishment programme was announced for the Enterprise service. Rotating refurbishment involved substituting non-Enterprise trainsets on an individual basis which began in November 2014 with the return to service of the first revamped coaches in November 2015. Refurbishment provided new mechanical running gear, in coach electronics and modernised interiors. The first refurbished set, consisting of DVT 9002 and Locomotive 206, operated a trial service from York Road Depot in Belfast to Dublin Connolly and back, on 15 October 2015. The same set operated the first official passenger service after its refurbishment on 16 November 2015. The refurbishment was officially completed on 10 April 2016, to coincide with the introduction of an enhanced Enterprise timetable. Mark 3 (2009–present) Although the majority of the Mark 3 stock was withdrawn by Iarnród Éireann in 2009, a handful of vehicles remain in use. In 2012, following extensive refurbishment, and modification to make them compatible with the existing De Dietrich stock, a total of four Mark 3 generator vans entered service with Enterprise to replace the need for the provision of Head-end power by the 201 Class locomotive. In 2014, Belmond, the owners of Venice-Simplon Orient Express, announced plans for a new Irish luxury train named as Belmond Grand Hibernian. To operate this service, Belmond procured eleven Mark 3 coaches from Iarnród Éireann for conversion into sleeping, restaurant and parlour cars. Between August 2016 and 2020, 10 of the Mark 3 carriages owned by Belmond are in service, painted
