Great Western Railway's refurbished restaurant-buffet (TRFB) coach 40743. The new green livery lacks the traditional yellow stripe above the windows so the only indication of its first class status is the white '1' on the silver doors which doesn't help people see that this train is running back to front with the first class at the country end and standard class towards London.
