Prag Tunnel

The 828.65 metre-long[3] tunnel finally broke through after two years of construction and operations began on the Central Line on 15 October 1846.

Between 1911 and 1914, the tube that is now used by the S-Bahn was shortened to 680 m in order to build the freight rail link between the Gäu Railway (Gäubahn) and Stuttgart North Station.

[1] In 1907, it was decided to carry out extensive restructuring on the Stuttgart railway facilities, including upgrading the Stuttgart-Ludwigsburg line to four-tracks.

On this occasion, the tunnel was shortened by additional excavations on the Stuttgart side to give it a length of 680 metres as well.

[1] After the commissioning of the Stuttgart 21 project, the bore of the Prag Tunnel that is now used for long-distance and regional train will no longer be used for this traffic.

The long distance bore is also to be maintained and will be available in future to supply two additional tracks under the so-called P option of the Stuttgart 21 project.
