Popis: The Semmering Base Tunnel (SBT) is about 27.3 km long and is being driven from the portal at Gloggnitz and from three intermediate construction accesses in Gostritz, Froschnitzgraben and Grautschenhof. The main components of the tunnel system are the two single-track running tunnels, cross passages at a maximum spacing of 500 m and an emergency station in the middle tunnel section, with two shafts about 400 m deep for ventilation and extraction in case of an incident. For organisational, scheduling and topographical reasons, the tunnel is divided into three construction contracts. The eastern contract section SBT1.1 ”Tunnel Gloggnitz“ has been under construction since mid 2015. Construction started on contract section SBT2.1 ”Tunnel Froschnitzgraben“ at the start of 2014. The western contract section SBT3.1 ”Tunnel Grautschenhof“ has been under construction since May 2016.
