Routemaster bus RML903 (reg. WLT 903), pictured at a rally at the Dean Forest Railway. It's wearing its original (1962) London Transport livery, with the modern affectation of a white London Northern Bus Company logo, which hints at the fact that it's not a privately preserved vehicle but a working show bus, a role it had already performed for many years with LT, and has continued to do so with London Northern's successors for over 20 years since.
