Map with all coordinates: 
The Stammham Tunnel (also known as the Stammham Tunnel ) is a railway tunnel on the Nuremberg – Ingolstadt high-speed line . The tunnel crosses under the Autobahn 9 at Stammham and therefore bears his name. With a length of 1320 m (route km 76.015 to 77.335), the tube is one of the shorter of the nine route tunnels.
The single-tube tunnel accommodates two tracks in slab track , which can be driven on as planned at 300 km / h.
course
The gradient of the route increases significantly in the tunnel to the north. It runs here on the districts of the communities Denkendorf and Stammham (from north to south).
The tube crosses under the motorway with little overburden over a length of around 300 m in a grinding cut. This is the second crossing under the motorway , next to the Irlahüll tunnel. The overlap is only a few meters. Towards the south, the line leading to Ingolstadt Hauptbahnhof moves away from the trunk road running to the east, while to the north of the tunnel, the railway and the motorway run parallel to one another over a longer section.
history
planning
In 1989 the structure was planned to be 1350 m long. The structure with a length of 1320 m was planned as early as mid-1994.
The structure was part of the planning approval section 63 of the new line and belonged to the southern construction lot .
construction
The tunnel was built using the mining method. In the area of the north portal, two open-plan blocks were built, and fifteen in the area of the south portal. Driving began in May 1999; the breakthrough took place on July 6, 2000.
After fine sands filled karst layers during excavation presented difficulties again and again, setting up a reconnaissance program was necessary. A total of around 1200 m³ of karst cavities were filled with concrete and a cement mixture.
The tunnel was part of the southern construction lot of the new line, which was commissioned by a consortium of Walter Bau ( Augsburg ) under the leadership of Dywidag .
business
The tunnel, together with the new line, was put into operation at the end of May 2006.
On February 14, 2008, an ICE traveling towards Munich caught a man in the tunnel. The passengers of the affected train were brought out of the tunnel by the fire brigade. The train was stopped in the tunnel. Around 100 passengers were evacuated via the emergency exit of the tube.
On the night of October 16, 2016, a rescue exercise with 50 passengers and around 300 rescue workers took place in the tunnel. A train came to a stop roughly in the middle of the tunnel, near the emergency exit.
security concept
To the east of the A9, an emergency exit leads from the tunnel through a shaft to the outside. The safety lighting is normally switched off.
