Towards the end of the nineteenth century the corridor revolution was in full swing and the LNWR, as the largest railway company in Britain at the time, began building corridor coaches en masse. The first 50ft Arc Roof coaches arrived before the turn of the century and were some of the company#s most successful - the Diagram 268 Corridor Third becoming the most numerous of any corridor vehicle to be outshopped by the LNWR's Wolverton Carriage Works during the pre-Grouping era.
The coaches built by Wolverton were used by both the LNWR and as West Coast Joint Stock (WCJS) - stock operated jointly by the LNWR and the Caledonian Railway between London and Edinburgh & Glasgow - and those built for the LNWR were generally 8ft wide. These included the Diagram 138 Corridor Tri-Composite, the D.316 Corridor Brake Composite, and the aforementioned D.268 Corridor Third, all of which form part of the Bachmann Branchline range. The Full Brakes built to Diagram 377 however were 8ft 6in wide and indeed, the Branchline models of the D.377 are a scale 6 inches wider than their passenger carrying counterparts.
Employed initially on primary express services and even used on excursions 'off territory' as far away as the Kent coast, Penzance and Scotland, the Arc Roof stock was later cascaded as new stock was introduced, before passing into LMS-ownership following the Grouping in 1923. Later still, the LMS transferred some Arc Roof coaches to the Midland & Great Northern which it operated in conjunction with the LNER. Those vehicles given to the M&GN would be the last to remain in service, with examples seeing use up until 1953.
