12092 was part of the first lot of production Mk. 3 coaches ordered by BR to lot number 30877 in November 1973 and constructed at Derby Litchurch Lane works during 1976 coming off the production line at the same time as the first production HST trailers. Built for West Coast main line services 12092 spent nearly thirty years operating on the route until being displaced by new Pendolinos.After West Coast service 12092 moved to ScotRail for 16 months from May 2004 until September 2005 to operate on the Edinburgh to North Berwick services. Displaced from Scotland by EMUs 12092 moved on to Norwich Crown Point depot where it was re-liveried in to National Express East Anglia livery and prepared for use on the London Liverpool St. to Norwich corridor, however, it never entered service and was instead used as a source of spares. It was later moved to Ilford works for refurbishment to operate on the East Coast main line but this was abandoned and 12092 moved again in to storage at Long Marston.
Purchased from Porterbrook Leasing on 1st January 2015, 12092 was moved from Long Marston to Ruddington on the Great Central Railway (Nottingham) on 28th March 2015 and following repairs, safety checks and a heavy clean re-entered service on 11th July 2015. The vehicle is currently fitted with 76 standard seats featuring a mix of airline style and bays of four around tables in 2+2 configuration. The interior is in an excellent condition and the seat covers have all been removed and deep cleaned which has made a big difference to the overall appearance of the interior. The toilets are also in a good condition and are in working order.
The vestibules did require some work including missing scissor mechanisms from the drop light windows and missing panelling however this work has been carried out along with a thorough external clean.
In December 2015 this vehicle along with the groups other two MK3 carriages headed north from Ruddington To Kilmarnock works in Scotland for a repaint. The livery? I guess you will just have to wait and see…
