There are proposals for a new railway station to serve Marsh Barton.
Marsh Barton was a medieval village south of Exeter and north of Alphington. At the turn of the 20th century the main part of Marsh Barton was the former Marsh Barton Priory also known as St Marys Priory (home to Augustinian Canons Regular). Either side on the west and east was the Exeter railway and Great Western Railway respectively, the former swung in a westerly direction whilst the latter made its way south to Dawlish.
The site was selected for a new greyhound track in 1928, and racing continued until 1957 when it was demolished.
