The Didcot, Newbury and Southampton Railway (DN&SR) was a cross-country railway running north–south between Didcot, Newbury and Winchester. Its promoters intended an independent route to Southampton and envisaged heavy traffic from the Midlands and North of England to the port, but they ran out of funds to complete the line to Southampton. The intended heavy through traffic never materialised, and the line was dependent on larger railways—the Great Western Railway and the London and South Western Railway—for support, which was not freely given. The line opened in two stages, in 1882 and 1885.
