Letter from John Urpeth Rastrick, Stourbridge to Timothy Hackworth, New Sheldon [sic]

Requests details of costs of keeping Stockton and Darlington locomotive engines in repairs for one year' and for particulars of the coal and water consumed during an experiment with the Royal George', and 'the No. of each of your Locomotive Engines - with the Men's Names who work them, that I may know ... one from the other'. He makes passing reference to Nicholas Wood at Killingworth, and mentions 'American Gentlemen' and tests carried out for them on Hackworth's engine between Stockton and Darlington. Mention is made of a set of wrought iron tyres which had been used at Killingworth for nine months without perceptible wear. Referenced in Robert Young, Timothy Hackworth and the Locomotive (London: Locomotive Publishing Company, 1923), p. 172.
