===Safety===
{{expand section|date=October 2018}}
The safety requirements on the rolling stock are similar to those of other long Swiss tunnels, including the ability for the [[Emergency brake (train)|emergency brake]] to be overridden.
 
One simulation indicates that ground surface displacements are primarily caused by water drainage induced by the tunnel and the consolidation of surrounding rock masses in the deep subsurface. Additionally, its findings suggest that the construction of the tunnel could lead to fault shearing due to the diffusion of pressure from drainage and resulting poroelastic stresses.<ref name="Zhao-2023">{{cite journal |last1=Zhao |first1=Chenxi |last2=Lei |first2=Qinghua |last3=Zhang |first3=Zixin |last4=Loew |first4=Simon |title=Causal mechanism of Gotthard Base Tunnel-induced ground deformation: Insights from 3D fully-coupled hydro-mechanical simulation and comparison to field measurements |journal=International Journal of Rock Mechanics and Mining Sciences |date=October 2023 |volume=170 |pages=105515 |doi=10.1016/j.ijrmms.2023.105515|hdl=20.500.11850/622062 |hdl-access=free }}</ref>
