Regent's Canal

Macclesfield Bridge before the explosion. After the explosion it was also known as Blow Up Bridge.

Just before 5am on 2 October 1874 the narrowboat barge Tilbury which was loaded with sugar, nuts, three barrels of petroleum and around five tons of gunpowder exploded right under the Macclesfield Bridge, just outside London Zoo. Until the explosion, the Tilbury was part of a convoy consisting of a tugboat and three narrowboats travelling westwards heading for a quarry in the West Midlands.[4] [5]

All the people on board died; captain Charles Baxton, a labourer named William Taylor, a third man and a young boy. The Macclesfield bridge was destroyed and rebuilt in 1876 reusing the cast iron pillars (made in Coalbrookdale according to an inscription at their top), but turning them by 180° (canal side towards tow path side) so tow rope grooves that were created before the incident can be seen on the outer side of the columns.

The explosion was heard 20 miles away. Debris flew in all directions, the roofs of surrounding houses blew off, windows smashed, trees uprooted and dead fish rained down on the West End. The tugboat's keel was found embedded in a house 300 yards away.[4] The bridge was nick-named the 'Blow-Up Bridge'.[5]

The damage would have been far worse had the barge exploded in the highly populated areas of Camden and Islington, which the convoy had passed through earlier that morning.

The canal company that owned Tilbury was condemned for gross negligence in permitting the “highly imprudent and improper” practice of carrying petroleum and gunpowder aboard the same barge.

The incident accelerated the passing of the Explosives Act 1875,[6] which regulates the manufacture and carriage of dangerous substances.[4]

There were a number of abortive projects to convert the route of the canal into a railway. In September 1845 a special general assembly of the proprietors approved the sale of the canal at the price of one million pounds to a group of businessmen[7] who had formed the Regent's Canal Railway Company for the purpose.[8] The advertisement for the company explained:

The vast importance of this undertaking, whereby a junction will be effected between all existing and projected railways north of the Thames, combined with the advantage of a General City Terminus, is too obvious to require comment. By the proposed railway, passengers and goods will be brought into the heart of the City at a great saving of time and expense, and facilities will be afforded for the more expeditious transmission of the mails to most parts of the kingdom.[8]

The railway company subsequently failed, but in 1846 the directors of the canal went about trying to obtain an Act of Parliament to allow them to build a railway along its banks. The scheme was abandoned in the face of vigorous opposition, especially from the government who objected to the idea of a railway passing through Regent's Park. In 1859, two further schemes to convert the canal into a railway were proposed. One, from a company called the Central London Railway and Dock Company, was accepted by the directors, but once again the railway company failed. In 1860 the Regent's Canal Company proposed a railway track alongside the canal from Kings Cross to Limehouse, but funds could not be raised. Further schemes over the next twenty years also came to nothing, with the Metropolitan Railway that opened to the south in 1863 serving much the same purpose of linking the lines radiating north of London.

In 1883, after some years of negotiation, the canal was sold to a company called the Regent's Canal and City Docks Railway Company at a cost of £1,170,585. The company altered its name to the North Metropolitan Railway and Canal Company in 1892, but no railway was ever built; instead it raised money for dock and canal improvement and eventually, in 1904, became the Regent's Canal and Dock Company.[7]

The Regent's Canal and Dock Company became part of the merged Grand Union Canal Company on 1 January 1929.

A new purpose was found for the canal route in 1979, when the Central Electricity Generating Board (CEGB) installed underground cables in a trough below the towpath between St John's Wood and City Road. These 400 kV cables now form part of the National Grid, supplying electrical power to London. Pumped canal water is circulated as a coolant for the high-voltage cables. The canal is frequently used today for pleasure cruising; a regular waterbus service operates between Maida Vale and Camden, running hourly during the summer months.[9]

Due to the increase in cycle commuting since the 2005 London Bombings[10] and increasing environmental awareness, the canal's towpath has become a busy cycle route for commuters. National Cycle Route 1 includes the stretch along the canal towpath from Limehouse Basin to Mile End. British Waterways has carried out several studies into the effects of sharing the towpath between cyclists and pedestrians, all of which have concluded that despite the limited width there were relatively few problems at the time of the audits.[11] More recently, in 2019, The Guardian reported on instances of conflict between pedestrians and cyclists.[12]
