Branksome railway station serves the Branksome and Branksome Park areas of Poole in Dorset, England. It is on the South Western Main Line, 110 miles 51 chains (178.1 km) down the line from London Waterloo.
The London and South Western Railway (LSWR) opened its line from Bournemouth to Poole in 1874, but the station was not opened until 1893 when it was the site of a junction with the Somerset and Dorset Joint Railway line whose trains to Bath started and finished at a terminus station, Bournemouth West. The S&DJR opened a locomotive depot at the station in 1895 which operated until closure of the line into Bournemouth West in 1965, after which the S&D trains ran, for the remaining few months of operation, into Bournemouth Central railway station, which had its own locomotive shed.
The line between Bournemouth Central to Branksome and Bournemouth Traction and Rolling Stock Maintenance Depot was electrified in 1967 to enable stock to access Bournemouth Depot. The route west of Branksome to Weymouth was electrified in 1988 using the standard British Rail Southern Region system of a third rail with 750 volts direct current.
The station is able to accommodate trains of up to five coaches; longer trains only open the doors in the first four or five coaches depending on the type of unit operating the service.
To the east of the station is the junction leading to Bournemouth Train Care Depot, built on part of the site of Bournemouth West carriage sidings. Trains can often be seen arriving on platform 2 and then reversing into the depot.
The station is served by South Western Railway, who operate express services from London Waterloo to Weymouth and stopping services from London Waterloo to Poole.
On Mondays to Saturdays the station generally sees 2 trains per hour to Poole and London Waterloo (one semi-fast and one stopping) and an hourly service to Weymouth. An hourly service operates in each direction on Sundays.
