The was authorised in 1873 and became part of a series of 'railway wars' in the south of England between the
Great Western Railway (GWR) and the
London and South Western Railway (LSWR).
First proposals The idea for a railway running north to south through
Hampshire stemmed from a proposal for the
Manchester and Southampton Railway during the
Railway Mania of the 1840s. It failed to gain parliamentary approval, largely because of opposition from the Great Western Railway. The idea of a direct line linking the manufacturing districts and the South Coast soon inspired another scheme, the
Oxford, Southampton, Gosport and Portsmouth Railway, which was generally known as "Bethell's Line" after John Bethell, a solicitor, who was the principal spokesman for the promoters. It failed to gain parliamentary approval in May 1846. It was intended as a connecting line, but the promoters offered no explanation of how the break of gauge would be dealt with. The earlier plans never progressed, but the idea of a railway linking the industrial areas of the
Midlands was revived in the 1870s, when the growth of the railway network meant that main lines from the north reached
Southampton via
Oxford,
Reading and
Basingstoke. This was an indirect and complex route, and in 1873 a parliamentary bill was submitted for the construction of the
Didcot, Newbury and Southampton Junction Railway. The company was incorporated by the '''''' (
36 & 37 Vict. c. ccxxix) of 5 August 1873, to build a line from on the
Great Western Main Line to a point north of on the
South West Main Line, whence access to Southampton was to be over the line. There was to be a branch from
Compton to
East Ilsley and a loop at
Whitchurch to join the
Basingstoke and Salisbury line of the . This line was to cross the
Berks and Hants Extension line at
Newbury without making a junction there, as that line was still
broad gauge at that time. By 1878 the company was on the verge of abandonment—a bill was submitted to Parliament for the purpose—and "with no vestige of any financial support", but due to the exertions of
Lord Carnarvon, a revised route was planned, connecting with the at Newbury and running through the station there; and forming the Micheldever junction nearer to that station together with a second spur at Whitchurch. These changes were authorised by the '''''' (
43 & 44 Vict. c. xlvii) of 9 July 1880, but Carnarvon's energy had already led to the first sod being cut on the Didcot to Newbury section on 26 August 1879. It had junctions with the at both places and used the stations, and the worked the line. Now with energetic plans, the company sought authority for its own line to Southampton, in length, to a location near to the
Royal Pier there from
Burghclere. There was to be a station at
Bargate, Southampton, and a line from Burghclere to on the , but the Micheldever line and the Whitchurch loops were to be abandoned. All this was authorised by the '''''' (
45 & 46 Vict. c. cxcvii) of 10 August 1882. The planned railway would run across largely empty country between Newbury and
Winchester before running down the eastern side of the
Itchen Valley, closely paralleling the 's main line on the western side, before crossing the rails on an overbridge just north of the boundary of the future site of the
Eastleigh Works at
Allbrook, then winding around the high ground north of Southampton to approach the city from the west to run into new terminus at Bargate (the planned station site is now occupied by the
Westquay shopping centre) and there was authorisation for a line to run south of this station to the Royal Pier, where steamers for the
Isle of Wight and
Cherbourg departed. The DN&S was proposed as a shortcut to the coast, saving compared to the existing route through
Reading. Deposited plans held by Hampshire record office show that the route south from Winchester was planned to run to the East of
Twyford,
Allbrook (where it was shown to cross the main line at Allbrook Lock by an overbridge),
Chandler's Ford (crossing the
Salisbury line to the west of Oakmount Road), pass under the current Leigh Road–Bournemouth Road junction, climb to a tunnel near the current Chilworth Arms Public House, descend through
Lordswood and the current Sports Centre area to traverse the east side of Dale Valley, swing south east under the current Winchester Road, pass through the site now occupied by Shirley Junior School, run to the south west of the current Wilton Road before crossing to the east side of Hill Lane and heading south towards the intended bridge over the . This final stretch is the area in which work commenced and the location of the surviving embankment, part of the land upon which preparatory clearance and culvert work was undertaken later became
The Dell football ground between Archers Road and Milton Road north of the unused embankment. The main passenger station was to be at Bargate Street, reached by a bridge over the
Southampton to Dorchester railway, and this area was to be widened throughout its length with considerable reclamation work and a sea wall built alongside station (at this time the Southampton West station was somewhat east of the present Central station position). Intermediate stations were to have been provided on the route and a story grew up that the
St James' Park, Southampton site in Shirley was excavated for this purpose, often repeated in local books. Archival research by the Shirley Local History Group, notably among the records of a local landowner revealed that a later revival of this scheme, the Southampton and Winchester Great Western Junction Railway, intended to use the park as the original route at this location had by then been developed. Plans and sections dated 1901 show the intended route of the railway as passing through the park from East to West. Records indicated that property sales were discussed for this scheme, which would have followed a slightly different route to the previous scheme in some areas without a tunnel at Chilworth. South of St James's Park at this time Didcot, Newbury and Station (now Stratton) Roads were named. Station Road also contained a police station. The only physical remnant of the project in Southampton is the tree covered embankment hidden behind current properties east of Hill Lane between Milton Road and Commercial Road. The deposited plans for the route through Southampton and in a detailed article about the Didcot Newbury and Southampton Railway in Southampton in the Hampshire Industrial Archaeology Society Journal, No. 26 (2018). The Winchester station was reached by a bored tunnel under The Soke; it was on a cramped site adjacent to St Giles' Hill. It appears that the line was built as far as
Bar End, where the goods facilities for Winchester were provided.
Worked by the Great Western Railway The Didcot, Newbury and Southampton Railway Company lacked the resources to operate its line, and it arranged for the
Great Western Railway to work the new line, providing
rolling stock and traincrews. At this time there was intense competitive rivalry between the and the . In 1876 the
Somerset and Dorset Railway had leased its line to the
Midland Railway and the jointly, giving independent access from the Midlands and the North of England to the South Coast. The was alarmed at this loss of primacy in the traffic, and it was pleased to undertake the working of the Didcot, Newbury and Southampton Railway (DN&SR) line, which it hoped would give it access to Southampton, in territory.
Reaching Southampton at last map showing (right) railways in the vicinity of Winchester. The is shown in yellow and the in blue. The company had expended all its financial resources in building the line, but its southern terminus was in Winchester: a cathedral city but not the commercial centre that had been planned. Without a through-line to Southampton the would not be able to attract the long-distance traffic that would restore in finances, but without that traffic it could not raise the funds needed to complete the final section of its planned route south of Winchester. In June 1885 the company estimated that it required £100,000 to complete the line into
Southampton, and Winchester and Southampton councils invested £15,000 and £70,000 respectively. The intended works at Southampton were considerable: £100,000 had already been expended, much of it on land acquisition. Sands, writing in 1971, said The D.N.&S. had bought a wide belt of land stretching from Wyndham place, outside the present
Southampton Central station, northwards along the east side of Hill Lane for about mile, then north-westward for nearly a mile towards St. James's church in
Upper Shirley ... Actual work seems to have been confined to the Hill Lane area where ... a viaduct was required ... The viaduct was completed for over half its length ... The unfinished viaduct has [since] vanished. The only way out was an accommodation with the ; under this agreement the company built a short connecting line from its Winchester station to
Shawford Junction on the ; this was authorised by the '
(51 & 52 Vict. c. cxlvii) and the ' (
52 & 53 Vict. c. cii) and opened on 1 October 1891. The now had its long-sought for control over traffic in its own territory and agreed to the Shawford link out of concern that the would provide the final funding to complete the independent line. Furthermore, seeing the danger of admitting trains worked by locomotives into Southampton, the agreed to the connection on condition that their own engines took over at Winchester and worked trains on to Southampton from there, over its own line onward from Shawford Junction. For the time being engines were forbidden to work south of Winchester, and there was always an engine change in the cramped station there until a pooling agreement finalised in 1910 removed this restriction.
Operation When trains from the north-west of England started running through to Southampton in the 1920s, the proprietors of the hoped their line would provide the north–south link, but in fact most trains were routed via Reading west curve, using the faster lines with greater capacity. ==Grouping==
