When the company obtained its original act of Parliament, the Manchester and Leeds Railway Act 1836, on 4 July 1836, this was for the main line only, between Manchester and Normanton, giving access to Leeds. The main line was complete in 1841; the extension to Victoria station in Manchester followed, being ready in 1844. It was obvious that many other important manufacturing locations were in the general area served by the company, and it began to take steps to connect many of them, by building branches, or later, by absorbing other companies.
Heywood branch 1841 Heywood was an important industrial centre, home to numerous cotton mills and an iron foundry. A single line branch to Heywood was made, opening on 15 April 1841 without getting parliamentary authorisation, until obtained retrospectively on 10 May 1844 in the '''''' (
7 & 8 Vict. c. xvi). It left the main line at
Castleton, but at the time the locality was known only as Blue Pitts, south-west of
Rochdale. It cost £10,000 to build. The branch trains used horse traction, until a locomotive was used on the line from 1 May 1847.
Oldham branch 1842 When the Hunt's Bank extension was authorised, an Oldham branch was included in the Manchester and Leeds Railway Act 1839 of 1 July 1839. It opened on 31 March 1842. The line was long, climbing from a junction on the main line at
Middleton; a station there was named Oldham Junction at first. The branch had a gradient of 1 in 27 for more than half the distance. The method of working was devised by Captain Laws, the company General Manager; it used a balancing load of mineral wagons on a reserved track, with a cable passing round a large drum at the head of the incline. This arrangement continued until some time between 1851 and 1856, after which ordinary locomotive working was used. "There is a steep gradient in this branch of 1 in 27, in length, situated between Middleton Junction and Werneth, Oldham, and a stationary engine was fixed at the top of the incline, with a rope attached to it, for the purpose of pulling up and letting down trains to the bottom of the incline."
Halifax branch 1844 Also authorised in the Manchester and Leeds Railway Act 1839 was a Halifax branch. It too was a short line, with severe gradients. Its junction with the main line at North Dean (later Greetland) faced Wakefield. The Halifax station was at Shaw Syke, and the branch opened on 1 July 1844.
Bolton and Bury 1846 Through the
Manchester, Bolton and Bury Canal Act 1791 (
31 Geo. 3. c. 68), the
Manchester, Bolton and Bury Canal Company had been created. In 1832, it decided to build a railway beside its canal, changing the company name to the Manchester, Bolton and Bury Canal Navigation and Railway. It never reached
Bury, and its "Manchester" terminal was in fact in Salford, and its title is usually shortened to the Manchester and Bolton Railway. The railway opened for public traffic as far as Bolton on 29 May 1838; there were six trains each way on weekdays and two on Sundays. From May 1844, the MB&BR reached Victoria station over the rails of the Liverpool and Manchester Railway. The Manchester and Bolton Railway saw that an ally in Manchester was necessary, and after failed talks in 1844, more favourable terms were offered by the at a meeting on 30 January 1846. An operating agreement came into force on 1 July, and by the
Manchester and Leeds Railway (Manchester, Bolton and Bury Canal and Railway) Act 1846 (
9 & 10 Vict. c. ccclxxviii) of 18 August 1846, the Bolton company was absorbed by the .
Huddersfield and Sheffield Junction Railway 1846 This line was authorised by the '''''' (
8 & 9 Vict. c. xxxix) on 30 June 1845 to connect Huddersfield with the
Sheffield, Ashton-under-Lyne and Manchester Railway near
Penistone. There was to be a branch to
Holmfirth. Amid considerable political tactics, the unbuilt Huddersfield and Sheffield Junction Railway was absorbed into the Manchester and Leeds Railway on 27 July 1846. The opened to the public on 1 July 1850. At first the worked the line (as it was disconnected from the ), but in 1870 the began running Sheffield-Huddersfield trains from Penistone.
1846 The West Riding Union Railways Company was formed in 1846 from the wreckage of George Hudson's duplicity; he had promised to promote a southward line from
Bradford to Halifax and elsewhere. The '''''' (
9 & 10 Vict. c. cccxc) of 18 August 1846 authorised a line supported by the Manchester and Leeds Railway; the act required amalgamation with the Manchester and Leeds Railway within three months. This was done on 17 November 1846; the actual construction of the line was carried out by the , which changed its title the following year to the Lancashire and Yorkshire Railway. The section from
Low Moor to Mirfield was opened on 18 July 1848, but the more difficult construction from Bradford to Low Moor was delayed until 9 May 1850, and Mirfield to Halifax on 7 August 1850; the Sowerby Bridge section opened on 1 January 1852.
Preston and Wyre Railway 1846 The Preston and Wyre Railway and Harbour Company was founded in 1835 to build from
Preston via
Poulton to the new town of
Fleetwood; it opened in 1840. The company amalgamated with the Preston and Wyre Dock Company to form the Preston and Wyre Railway, Harbour and Dock Company in 1839. A branch from Poulton to
Blackpool North and another to
Lytham, both opening in 1846. With the absorption of the Manchester and Bolton Railway and a share of the
North Union Railway in 1846, the Manchester and Leeds Railway had now extended its influence to Preston. It had already had a close association with the Preston and Wyre Railway in running excursion traffic, and a closer connection was appropriate. The amalgamation of the two companies was authorised by the
Manchester and Leeds Railway Act 1846 (
9 & 10 Vict. c. cclxxvii) of 3 August 1846. ==Ashton, Stalybridge and Liverpool Junction Railway 1847==
