Four second class sitting cars coded OFS with a seating capacity of 41 with 2 and 2 seating and a staff and a hostess compartment were originally constructed & numbered 2257 to 2260. Four first class sitting cars were also constructed and coded OBS numbered 2261 to 2264 and had a seating capacity of 28 with 2 and 1 seating and a staff and a hostess compartment.
During the late 1970s 2257, 2260, 2261 & 2263 were converted to day-night seating with a passenger capacity of 42. As part of this conversion the toilets at the men's end were removed & replaced by four small cubicles, two for each sex. The ladies toilet, staff & hostess compartments were removed to allow for the main saloon to be lengthened. A new staff compartment was installed in the remaining space. These converted cars were recoded ODS. Second class sitting car SFS 2267 was also converted to an ODS car as well during 1977.
In 1985 2262 & 2264 were rebuilt with day-night seating with a capacity of 34 passengers and recoded ODL.
In 1989 ODS 2263 was rebuilt with a buffet & serving counter and a capacity of 30 passengers, being recoded RDS.
