The Sutton Park line is a freight-only railway line running from Walsall to Castle Bromwich and Water Orton in the West Midlands, England. It is an important and strategic route, as it enables most freight trains to avoid congestion at Birmingham New Street station. It gets its name as it runs through Sutton Park at Sutton Coldfield, West Midlands. Opened in 1879 as one of the Midland Railway branches around Walsall, the line carried passenger services until 1965.
