I am a returning modeller after many years absence and building a 1950 BR branch in Great Eastern territory. Slight problem, no motive power in RTR! I dont fancy paying £120 plus for a kit which might not run so I am doing one of K Chadwick's conversions from Model Railway Building on the Cheap!. But where can I get Hornby spares from,preferably on line? Chadwick gives a list of suppliers but most are not on line, any ideas please?
