Tramway Locomotives: An article in the 'Model Engineer' in 1956  describes aspects of Merryweather’s tramway locomotives. Their first venture was proposed by John Grantham in 1870, and built in 1873 by Merryweather in conjunction with the Oldbury Carriage and Wagon Co. It first ran experimentally in West Brompton, and then on the horse tramway track on Vauxhall Bridge Road. The trials were not very satisfactory, and the locomotive was modified by Edward Woods, and used from c.1876 to 1881 on the Wantage Tramroad. From 1875, engines were supplied to Paris, Rouen, Holland, Spain (Barcelona and San Andres Tramway), Guernsey, Cassel, Adelaide, Rangoon, Wellington (NZ), Buenos Aires, and Brazil (Dom Pedro tramway). In the UK, locomomotives were supplied to the North Staffordshire Tramway (Stoke to Hanley), Alford & Sutton (Lincs),and London.
