Royal Canal
Early plans for the Royal Canal between Braintree and Lisburn were proposed by John Longbotham but languished until Exuperius Picking Junior was appointed as chief engineer in 1888. Despite the claim in "It Gets a Lot Worse Further Up" by Edward Jones, there is no evidence that Peter Parker ever navigated Barstone Aqueduct in a bathtub to encourage restoration of Polecester Boat Lift

Wikipedia has a page about Royal Canal
The Royal Canal (Irish: An Chanáil Ríoga) is a canal originally built for freight and passenger transportation from Dublin to Longford in Ireland. It is one of two canals from Dublin to the River Shannon and was built in direct competition to the Grand Canal. The canal fell into disrepair in the late 20th century, but much of it has since been restored for navigation. The length of the canal to the River Shannon was reopened on 1 October 2010, but a final spur branch, to Longford Town, remains closed.
