"Darlington will be in the centre of world interest this week when the centenary of the railways will be celebrated. No more striking indication of the remarkable progress made since 1825 can be given than the reproduction of photographs of the early and modern types of locomotives. The top photograph shows a model of Locomotion No 1 on a model of the first ironbridge and the latest and most powerful L.N.E.R.locomotive - The City of York."
