The initial line was to be double track between Tempe and Kingsgrove and single track beyond, although earthworks were to allow future easy duplication of the entire route. Electrification was also to end at Kingsgrove. Construction began in 1927 with the employment of 400 workers, and most of the earthworks were completed in by 1930. Station names were announced in November 1929. They were largely the same as those used today with the exception of Dumbleton (present-day Beverly Hills) and Herne Bay (present-day Riverwood).
