Eventually, the city and the Railway Administration withdrew from the original ground variant and a tunnel variant was chosen.

“To help end the decades of debate, we are in favor of this proposal. In addition, Prague will suit it, because it is the most direct option. The development of public transport and railways is definitely the way to go. We need to get this railways as soon as possible,” said the deputy mayor. Adam Scheinherr (Prague to Himself).

In the southern variant, the tunnel will usually lead at depths of more than 50 meters below the terrain and buildings. The track will go according to the plan in the direction from Dejvice to Veleslavín gradually from a depth of 20 meters below the surface to a depth of more than 50 meters.

TBM technology will be chosen for the excavation. According to a document approved by deputies, the most favorable stability is overburden. “The chosen variant, the technical solution and the depth of the tunnels are prerequisites for the maximum and unchanged comfort of the site above the tunnels, as the vibration and noise effects are completely negligible,” the material writes.

They recommended the approved variant as the best of the assessed expert opinions prepared by a team from the Czech Geological Survey and a team of experts from the Ruhr University in Bochum. According to their conclusions, the southern variant is considered to be the least conflict with the affected area.
