The Cooke and Wheatstone telegraph was an early electrical telegraph system dating from the 1830s invented by English inventor William Fothergill Cooke and English scientist Charles Wheatstone.It was the first telegraph system to be put into commercial service.Once it was known that Tawell had boarded a train to London, the telegraph was used to signal ahead to the terminus at Paddington and have him arrested there.

Cooke eventually bought out Wheatstone's interest in exchange for royalties.

The change was motivated by the economic need to reduce the number of telegraph wires used, which was related to the number of needles.

The change became more urgent as the insulation of some of the early installations deteriorated, causing some of the original wires to be unusable.

The Blackwall Tunnel Railway (another rope-hauled application) was equipped with the Cooke and Wheatstone telegraph when it opened in 1840, and many others followed.

In September 1845 the financier John Lewis Ricardo and Cooke formed the Electric Telegraph Company.
