It is reportedly planned to double sections of the <i>Steirische Ostbahn</i> (Graz – Gleisdorf – Szentgottard [HU]), but information on this is sparse: [http://de.wikipedia.org/wiki/Steirische_Ostbahn Wikipedia's Steirische_Ostbahn entry] indicates a south to east Graz avoiding line (otherwise any trains between the Koralmbahn and Szentgottard would have to run round in Graz) and a possible completion in 2020. However, the project does not appear in [http://www.oebb.at/infrastruktur/de/5_0_fuer_Generationen/5_4_Wir_bauen_fuer_Generationen/5_4_1_Schieneninfrastruktur/index.jsp OeBB Infra's list of projects].
'''Threatened passenger lines ''' (position at September 2016 with updates)
The Achenseebahn (T311: Jenbach - Achensee) is potentially in danger of closure at the end of the 2019 tourist season owing to poor track condition. As it is a tourist line, the Tirol region does not wish to subsidise it.
