 A branch line connecting to Maryborough was also opened from Theebine, south of Tiaro, to Kilkivan in 1886, and was later extended to Murgon, Proston, Windera, Kingaroy, Tarong and Nanango (the latter by 1911).A branch line from Mungar, south of Maryborough, to Broweena opened in 1889, and this line eventually extended to Gayndah, Mundubbera and Monto (1929).Coal from the Burrum fields eventually required better port facilities and a branch line was built to Pialba in 1896, from Colton railway station (just north of Aldershot), between Maryborough and Burrum.
