BCN Main Line
The BCN Main Line, or Birmingham Canal Navigations Main Line is the evolving route of the Birmingham Canal between Birmingham and Wolverhampton in England.
The name Main Line was used to distinguish the main Birmingham to Wolverhampton route from the many other canals and branches built or acquired by the Birmingham Canal Navigations company.
On 24 January 1767, a number of prominent Birmingham businessmen, including Matthew Boulton and others from the Lunar Society, held a public meeting in the White Swan, High Street, Birmingham to consider the possibility of building a canal from Birmingham to the Staffordshire and Worcestershire Canal near Wolverhampton, taking in the coalfields of the Black Country. They commissioned the canal engineer James Brindley to propose a route. Brindley came back with a largely level but meandering route via Smethwick, Oldbury, Tipton, Bilston and Wolverhampton to Aldersley.
On 24 February 1768, an Act of Parliament was passed to allow the building of the canal, with branches at Ocker Hill and Wednesbury where there were coal mines. The Staffordshire and Worcestershire company was given the right to make the connection to their canal if the Birmingham company failed to do so within six months of opening. On 2 March Brindley was appointed engineer. The first phase of building was to Wednesbury whereupon the price of coal sold to domestic households in Birmingham halved overnight. Vested interests of the sponsors caused the creation of two terminal wharves in Birmingham. The 1772 Newhall Branch and wharf (now built upon) originally extended north of, and parallel to Great Charles Street. The 1773 Paradise Street Branch split off at Old Turn Junction and headed through Broad Street Tunnel, turned left at what is now Gas Street Basin and under Bridge Street to wharves on a tuning fork-shaped pair of long basins: Paradise Wharf, also called Old Wharf. The Birmingham Canal Company head office was finally built there, opposite the western end of Paradise Street.
By 6 November 1769, 10 miles (16 km) had been completed to Hill Top collieries in West Bromwich, with a one-mile summit pound at Smethwick. Brindley had tried to dig a tunnel through the hill at Smethwick but had encountered ground too soft to cope with. The canal rose from what is now the Birmingham Level through six narrow (7 ft, 2.1 m) locks to the summit level and descended through another six at Spon Lane. Water was brought from purpose-built reservoirs: Smethwick Great Reservoir (now built upon, holding 1514 locks of water), another smaller pool at Smethwick (holding 500 locks), and then from Titford Pool to supply the summit level.
In 1770 work started towards Wolverhampton, from above the third Spon Lane lock at what is now the Wolverhampton Level. On 21 September 1772 the canal was joined with the Staffordshire and Worcestershire Canal at Aldersley Junction via another 20 locks (increased to 21 in 1784 to save water). Brindley died a few days later. The canal measured 22+5⁄8 miles (36.4 km), mostly following the contour of the land but with deviations to factories and mines in the Black Country and Birmingham. A branch led to Matthew Boulton's Soho Manufactory.
The original Birmingham Canal was extremely successful but there was a problem with supplying sufficient water to the Smethwick Summit. Matthew Boulton's partner, James Watt, had just patented an improvement to the steam engine involving an external condenser which improved the efficiency (and therefore reduced the amount of coal needed to run it). Steam engines were constructed at either end of the Smethwick Summit to pump water used in the operation of the locks back to the summit. The Smethwick Engine (5 June 1779) pumped water from the Birmingham side of the summit, and another, the Spon Lane Engine (April 1778) operated from the Wolverhampton side.
In 1784, after two years of counter-productive attempts at legislation, the Birmingham and Fazeley Canal Company (created to propose a competitive canal from the coal fields to Birmingham and also a link to the Coventry Canal at Fazeley) merged with the Birmingham Canal Company (ten years later the name of the merged company was changed to the Birmingham Canal Navigations Company) and the Birmingham and Fazeley Canal was started. This created an even greater need for water to supply the thirteen locks at Farmer's Bridge and eleven at Aston, all running downhill and taking water out of the Birmingham system.
