}}The BR Mark 1 Corridor Second (SK) was the most prolific of the Mark 1 passenger stock, with more than 2,200 built. Those in the Western and Southern regions seated eight per compartment, while those on Midland and Eastern routes seated six per compartment. Early examples featured veneered walls, while later batches used formica laminates. The SKs were an early candidate for withdrawal, being replaced by Mark 2 Open, HST sets and Networker Turbo units.<ref name = StockBook>SVR Stock Book 9th edition</ref><ref name = SVRCT>SVR Charitable Trust</ref>.

==Preservation==‘18771’ arrived on the SVR on 9 September 1991 from London’s Old Oak Common, courtesy of [[The 75069 Fund]]. The carriage was delivered to the SVR by [[GWR 3717 City of Truro|3440 City of Truro]] which arrived in steam to attend that year’s [[Autumn Steam Gala]].<ref>SVR News 101</ref> It entered service still in Network South East striped livery, before being repainted into [[Carriages#Set_M|BR Maroon]] the following summer.<ref>SVR News 104</ref> It then re-entered service, still suffering from a wheel flat which was present on arrival and which was not cured until a bogie swap was carried out during a minor overhaul in summer 2003.<ref>SVR News 144</ref> By May 2007 it was ‘10 years overdue for a repaint’<ref name=SVR191>SVR News 191</ref> and was photographed in poor condition for the Railway Heritage Register Carriage Survey.<ref>[[http://www.cs.rhrp.org.uk/se/CarriageInfo.asp?Ref=1784 25771 on Railway Heritage Register On-Line]</ref> It was then sent to Arley to serve as a classroom during the 1940s event and was trapped there for 18 months following the [[2007 Storm Damage]]. During that time the batteries went flat, the doors swelled up and seats went mouldy. It was eventually retrieved and put into store, being considered possibly surplus to requirements.<ref name=SVR191/><gallery>BR_25771_GarethPrice.jpg|25771 prior to the 2015 repaint (Gareth Price)</gallery> In 2015 the need was identified for a 'spare' carriage to replace vehicles from [[Carriages#The carriage sets|Set N]] that were due to be withdrawn in turn for overhaul. 25771 was thoroughly overhauled at [[Carriage Repair Works|Kidderminster Carriage works Works]], having been photographed there in in May 2015 on Facebook, and outshopped in a later variant of BR maroon livery-with maroon ends. Appropriately the interior is typical of latter day Mk 1, being clad with light grey patterned Formica. For The 48 seat configuration with which the present its primary function is to replace vehicles carriage was originally fitted has been replaced with a 64 seat configuration (the change dating from the Network South East era?) and the carriage data plate edited accordingly (the plate also shows a weight of 37 tons rather than the 36 tons recorded for Lot 30685). <gallery>25771_Data_Plate_20180725.jpg|Data plate</gallery> Following this overhaul, 25771 was used as a stand-in for Set N that are withdrawn in turn as intended. It has since been available for overhaul, but once that programme is completed this very useful carriage is certain to quickly find other workoperational use as required.
