Tourist Standard Open - Mark 2

Mark 2

The Mk2 TSO was a direct development of the Mk1 version, and the early Mk2 TSOs (Mk2 and Mk2a) had an almost identical layout, including the pair of toilets either side of the gangway at one end and the two identical four-bay saloons separated by a just-off-mid-coach transverse vestibule, with further transverse vestibules at the outer end of each saloon. Unlike those in the Mk1 TSOs, the Mk2 saloons were not further subdivided. The Mk2b design saw the centre vestibule abolished, although the mid-coach divider was retained to still give two saloons of four bays each. The space saved by the abolition of the centre vestibule was used to re-locate the toilets, with one now placed at each end, with the entrance vestibules beyond them. This enabled the fitting of wide wrap-round end doors in place of the traditional narrow ones. The basic layout of the Mk2 TSO remained unaltered from the 2b to the 2f, although finish, materials, seating, and ventilation arrangements changed with each new build. Full details of the various changes are listed in the Mk2 Development Table in the main Mk2 article.
