An excellent model of the BR unclassified restaurant coach in the corporate blue and grey livery.
These coaches remained in mainline express trains for many years after the standard coaches were relegated to secondary services, as no buffet cars were built to match the Mk2 stock of the late 1960s and 70s. The RU design was equiped with a large kitchen able to provide full meal service when required and many were equiped with a buffet serving hatch for customers requiring tea/coffee and snacks.
Eras 6-7.
