With the introduction of N cars and the new passenger services, older steel cars were also revamped.
Between 1983 and 1985, ten steel cars were modified to BRS, a car with combined sitting accommodation and a mini refreshment service.
Some cars were surplus from the altered standard guage passenger train working. Two overnight trains were combined into one train leaving a surplus of cars which were returned to broad guage.
The BRS car numbers were: 1, 2, 3, 224, 225, 226, 227, 8, 9, 10. Midway through the project the steel cars were allocated to '200' number range. Cars 1,2,3,8,9,10 became 221, 222, 223, 228, 229 and 230 between 1984/1985. Cars 224, 225, 226, 227 were converted directly with those numbers.
The BRS group came from classes: _AS_, _BS_, MBS_, VFR_, VFS_.
