Tourism was initially driven by the spring waters. The arrival of the Warwick and Napton Canal (later amalgamated into the Grand Union Canal) officially opened in 1799 as the primary means of cargo transport and led to growth in other industries until rail gradually took over in the mid 19th century, The canal supplied coal to the gasworks on Tachbrook Road, providing gas to light the town from 1835. Pig iron, coke and limestone were delivered by canal, allowing a number of foundries to be established in Leamington, specialising in cast iron stoves. Today the Eagle Foundry, dating from at least 1851, continues to manufacture Rangemaster Aga stoves. The Imperial Foundry, dating from around 1925, was subsequently taken over by Ford, casting engine blocks until its closure in 2008.
