In the metropolitan region Stuttgart, the first digitalised railway junction in Germany is being built, which integrates all kinds of trains and plays a trend-setting role for the future of railway traffic. Numerous innovations maximise the capacity and efficiency of railway operation and set new standards for mobility in the region. LEONHARD WEISS was awarded the contracts for various partial projects for this important construction project:
Underground cable engineering for Stuttgart-Vaihingen / Fildern
In connection with the project Stuttgart 21, LEONHARD WEISS realises the section Stuttgart-Vaihingen. This section includes underground cable engineering and the laying of about 510 km of cable along the urban railway ”Filderbahn“ and the long-distance railway line “Gäubahn“. In addition to that, 20 km of new cable conduit system, 96 track crossings and a new location for a track field concentrator are built. Simultaneously with the contractual performances, we were awarded the contract for the construction of approx. 260 signal foundations, as well as the foundation and construction of field access elements by the company Hitachi Rail (formerly GTS Deutschland GmbH). Early in 2024, DB PSU also awarded us the contract for the additional installation of five new points, incl. all auxiliary works, like for ex. track field lighting and point heating stations at the station S-Vaihingen.
A particular challenge resides in the mainly rail-bound execution of the works in a limited space in an urban area, which often needs to be carried out during short shutdown intervals during the night. In spite of challenging conditions and changing execution periods caused by the customer, the works were carried out successfully and reliably up to the present.

Digital rail for the section Bad Cannstatt – Waiblingen
In autumn 2021, LEONHARD WEISS was awarded the conversion of the station Bad Cannstatt and the extensive underground cable engineering works and cable pulling works for the Digitaler Knoten (digital junction) Stuttgart in the are Bad Cannstatt to Waiblingen. Due to delays, two long shutdown intervals needed to be organised at very short notice, in order to catch up the delay in time. During the complete shutdown from 12th March to 29th July 2023, divided up into two shutdown areas, 14 kilometres of cable route along the line were realised as temporary construction, 50 new track crossings were built, and a total of 40 signal foundations was established.
For the foundation of 16 signal brackets, bored piles of a depth of up to 22 metres needed to be built. As almost all locations could not be accessed by road, the bored piles needed to be founded by rail-bound machines. In order to generate an advance in time compared to the traditional drilling engineering, the new track foundation train of the company Hering was used for the first time. Thanks to this new technology, the removal of the tracks and relocation of the catenary system, which is required when using traditional drilling machines, was no longer necessary, and generated an enormous advance in time. Further challenges are coming up in summer 2025, when the upcoming works are carried out during continuous shutdown intervals. In spring and summer 2026 the connection of the station Bad Cannstatt to the tunnel leading to the low-level station will be carried out and the taking into operation of the Digitaler Knoten (digital junction).

Underground cable engineering in Stuttgart-Untertürkheim
In connection with the Digitaler Knoten (digital junction) Stuttgart, LEONHARD WEISS was awarded the contract for building the basis for the control of the railway junction Stuttgart by means of digital control centres. Our construction services included the foundation and production of the environment of four track field concentrators in the suburbs of Stuttgart Untertürkheim, Münster and Hafen, the construction of four signal brackets incl. installation, the production of 19 kilometres of cable conduits and 95 track crossings, as well as the relocation of over 500 kilometres of cables. In addition to that, we were awarded the contract for the production of 300 signal foundations on nine different railway lines by Thales Deutschland. The foundations were realised as driven casing pipe foundations, concrete monoliths and concrete element foundations.
The construction project stood out thanks to its challenging logistics, as well as the high environmental requirements. In addition to that, the access to the narrow building space in an urban area was required by several construction projects simultaneously, so that the coordination between various construction projects was necessary.
