From the mid-1860s until the mid-1880s, the station was a significant station in its own right on the Southampton and Dorchester Railway and the point of interchange for other lines. The Somerset and Dorset Joint Railway ran from Wimborne Junction, just south of the station on the other side of river, initially to Blandford and then Burnham in Somerset and finally Bath ; Wimborne was the point of reversal for trains to and from Poole. The second route was the Salisbury and Dorset Junction Railway, a minor line which branched off at West Moors; the station there was not opened until 1867, and goods traffic largely continued to be worked through to Wimborne and later beyond. The final new railway, branching off the original main line at New Poole Junction, was to Poole and onwards to Bournemouth.
Decline
Bournemouth's rapid development in the late Victorian era as a residential town and holiday resort indirectly led to the decline of Wimborne station. The Somerset and Dorset avoided the awkward reversal there by opening a bypass from Corfe Mullen to Broadstone in 1885 and 1886. A handful of local S&D passenger trains still ran into Wimborne, as well as some goods trains as the large yard made for a more convenient point of interchange. Worse still came in 1888 when Wimborne was bypassed by the opening of a direct line to Bournemouth from the east. When that was extended in 1893 across Poole Harbour to join with the original Southampton and Dorchester line at Hamworthy Junction via the Holes Bay Curve - forming an alternative through-route between Southampton and Weymouth via Bournemouth - this meant that most main line passenger trains to and from London, Dorchester and Weymouth had no need to run through Wimborne. Nevertheless, the generally increasing level of traffic on the railways up to 1914 meant that it was still a busy station, although post-war economies led to the withdrawal of the last S&D passenger trains from 11 July 1920, followed by milk and parcels in February 1932, with freight traffic ceasing completely from 17 June 1933. Loss of the S&D traffic only left Wimborne with the infrequent pull-push services between Brockenhurst and Bournemouth West, a handful of trains from Salisbury and some long-distance Summer Saturday traffic when the station was used to relieve Bournemouth. This seasonal holiday traffic built up in the inter-war period and boomed in the 1950s. Goods trains also used the route all year around for the same reason.
Closure
In its final years the station suffered from an air of neglect, although photographic evidence suggests that the main buildings were kept in a decent state of repair into the early 1960s. Wimborne station closed to passengers as from 4 May 1964 along with all others on the bypassed original line, an early casualty of the Beeching Axe programme of economies. Regular goods services ceased from 28 February 1966 when sundries were concentrated on Bournemouth Central. This led to a rationalisation of the station's track and signalling for the purposes of dealing with the remaining goods traffic, and from 24 July 1966 "siding working" was introduced whereby the Down line was put out of use and services were concentrated on the former Up line. Signals were removed, but the signalbox remained in service as a ground frame until 8 January 1967 when all points were converted for manual operation. Goods and parcels trains continued to serve the station from Poole, running through to West Moors and Ringwood until August 1967. Thereafter traffic to Wimborne consisted mostly of coal and similar wagon loads, with the continued use of the line for an RAOC fuel depot just beyond West Moors keeping trains running through until the summer of 1974. The track north of Wimborne was lifted from October 1974, back to a point immediately south of Leigh Arch, the dangerously narrow and low bridge over what was then still the busy A31 road. This allowed the bridge to be demolished. For just over another 30 months, the occasional goods train disturbed the peace of Wimborne's decaying station, although by then the main reason for the line's survival was the use of the goods yard by a company building exhibition trains.
The site today
The site is now partly occupied by the weekly Wimborne Market while industrial and commercial units cover most of the rest. Much of the original embankment was removed in the mid 1980s, although it is not clear where the spoil was taken. Some oral accounts say it was used for construction of the Wimborne bypass while others suggest reclamation work in Poole Harbour near the town's railway station.
