Mark 1
The Mk1 TSO contains eight seating bays, three transverse entrance vestibules, and two toilets arranged either side of a central corridor leading to the gangway at one end. The eight bays are distributed along the coach in two saloons of four bays either side of the almost-central door vestibule (this is slightly offset towards one end by the presence of the toilets at the other end), and the saloon nearest to the toilets is further divided into two saloons of two bays each by a transverse partition. The bay spacing is 6'6", this being the standard for Mk1 Third / Second / Standard class, and identical to the compartment spacing in Mk1 side corridor stock.
The first 20 Mk1 TSOs (3700-19) did not have the centre door vestibule, so the 8 seating bays were spread equally along the saloon length.
No Mk1 TSOs are still in use with franchised TOCs, however a number are still in active service with railtour and charter operators. They are also found on almost all mainland UK standard gauge heritage/preserved/tourist lines.
