In 1826 work began on the construction of the railway starting from Bolton levelling the ground for the line up to Chequerbent under the supervision of local engineer,
Robert Daglish. The B&LR found it needed to revise some of the clauses set out in the original act of Parliament and they prepared a second bill in 1828. The second act, the '''''' (
9 Geo. 4. c. viii), received assent on 26 March 1828. This Act enlarged the company's powers, and it authorised the raising of an additional £25,000 to meet the increased costs of construction as well as specifying the
track gauge for the railway as being between the inside edges of the rails, as well as between the outside edges. Sometime after this the line became a standard gauge line at . The acts of Parliament for the B&LR also authorised branch lines at the Bolton end, to the Union Foundry on Deansgate, to
William Hulton's coal yard at Great Moor Street and to the
Manchester, Bolton and Bury Canal. The branch to the canal was never built and the branches to Great Moor Street and Deansgate opened for freight in 1829. The first section of track between Derby Street Bolton and
William Hulton's
collieries at Pendlebury Fold near Chequerbent in
Westhoughton was officially opened on 1 August 1828 The official opening of the completed part of the railway (which the
Manchester Guardian reported as being from Checkerbent to the town of Bolton) was witnessed by "an immense concourse of people". They saw a procession of a "new locomotive engine made by Messrs. R. Stephenson and Co. of Newcastle ... to which were attached six waggons filled with people, and decorated with numerous flags and streamers; then followed a very elegant and commodious coach, intended at some future period to convey passengers on the railway. This was filled with ladies amongst whom was Mrs. Hulton. Then followed seven other wagons, decorated with flags, and crowded with passengers, including the musicians of the Bolton old band, who occupied the two last waggons, and played a variety of appropriate airs, during the procession". The procession started at 12.15 pm with the locomotive drawing the thirteen waggons and the coach from Pendlebury Fold, near Hulton Park, to Top o' th' Pike where the stationary engine was situated. There were about 150 people on the train which travelled at about . On reaching the stationary engine the waggons were detached and "Mrs. Hulton, after a short address, baptised the engine by the name of the
Lancashire Witch". She then presented a garland of flowers to the engineer, who treated it, in the newspapers view, rather unceremoniously by placing it on the furnace-pipe (presumably the chimney) where the flowers soon underwent a lamentable change. The engine was sent back to one of Mr. Hulton's collieries from whence it returned hauling six waggons containing about two tons of coal which it drew with great ease at about . The locomotive was again detached from its train and demonstrated some of its abilities, starting and stopping under control even from speeds estimated up to . After the demonstration the coach and waggons were attached to the rope of the stationary engine and proceeded down the inclined plane towards Bolton. The waggons were "occasionally moved with great celerity, and occasionally stopped by means of brakes applied to the wheels, in order to shew the command possessed over them by the engineer, in case of any accident or obstruction". The crowd was so large that several people were thrown onto the railway where they were "placed in the most imminent peril" and one man was reported as nearly falling under the wheels of a waggon before it could be stopped, he was reportedly severely hurt. At the bottom of the incline it was intended that the waggons should be horse-drawn to the terminus but the crowd man-handled the waggons to their destination. Upon arrival, a considerable number of gentlemen sat down to an excellent dinner at the Commercial Inn, Mr. Hulton in the chair. The coach used by the ladies during the opening was loaned by the L&MR and another carriage was borrowed from them in December 1829 for 'an experiment in passenger carrying' but passengers weren't regularly carried until 1831. The line was completed through to the Leeds and Liverpool Canal at Leigh by end of March 1830. By then the construction of the
Kenyon and Leigh Junction Railway which provided a connection with the
Liverpool and Manchester Railway was already well advanced. ==Description of the route==
