Efficient solutions for complex challenges in track infrastructure construction
The most important point in the construction sector is to make the right decisions from the beginning. Thanks to our many years of experience, we give you a detailed summary of your opportunities, risks, and alternative ways of achieving your project objective. From the feasibility study to wholistic planning and negotiations for land acquisition up until the erection of the buildings for track infrastructure construction of tomorrow we cover the entire range of performances for your individual construction project.





Complex assignments in the field of track infrastructure involve very specific requirements when it comes to adherence to schedules and logistics. This demands a detailed knowledge of the construction processes, their safe handling and the knowledge of special methods. Logistics are of essential importance in this case, in order to be able to deliver supplies “just in time”. For a smooth running of your project, we use the tools of the LEAN-Management.
With our experience and flexibility, we are available for your projects as a strong partner. LEONHARD WEISS offers everything from one source – from project development over planning up until control over installations.
Our expertise in projects is very diversified which gives you the opportunity of realising even complex projects in one package with us as your central partner.
Our range of services
The requirements in the field of modern safe railway operation are high and are increasing all the time. Digital Control Centre Technology and the European Train Control System (ETCS) are of special importance, as they stand for the beginning of a new railway era with the Digital Rail Germany (Digitale Schiene Deutschland) by creating a European standard for control, communication and safety systems. LEONHARD WEISS is an expert for the technical and functional erection of electronic and digital control centres, including all incidental services in connection with the railway. We can supply you with the performance of all railway-specific services.
Projects are carried out with the highest precision – economically, reliably and rapidly – even during railway traffic. Thanks to innovative, state-of-the-art machine technology, the right project management, and well-established teams we master all assignments.
Electric connection methods and cabling are faced with steadily increasing challenges, in order to fulfil the future requirements of data traffic. LEONHARDWEISS offers all services from one source, in order to produce performant and reliable cable networks.
We take your challenge in the field of underground cable construction – no matter if fibre optic cable routes, GSM-R or ETCS. We build new cable routes, for example track and road crossings, as well as connections to the existing infrastructure and carry out all required performances to ensure your connection. Difficult accessibility or lacking documentation of existing structures are no obstacles for us.
The protection of residents from noise of infrastructure situated close-by is an important factor form many operators. The challenge is to find the right solution for you as operator, as well as for the residents, depending on the exterior framework conditions.
We support you from the planning phase up until the realisation and offer you efficient solutions. Next to the traditional noise protection walls, we propose a special solution for projects, for which traditional noise protection is difficult to realise due to the lack of space or bad accessibility with the NOISE BREAKER.
From the suitable foundation, over torsion bars, up until escape routes and the complete earthing we plan and build the optimum solution for you.
Passengers begin and end their journey at the traffic station. The embarkments, stops and ways will thus be remembered. It is our utmost concern to design this infrastructure according to the rules, to make it modern and safe.
With our expertise and experience we build new traffic stations or renovate existing ones on the basis of detailed planning. Some of these assignments are roofs, ways, lifts, passenger underpasses and overbridges, as well as lighting and pavements. We also develop the optimum solution for temporary arrangements or the extension of existing railway platforms with you.
Where railway facilities and road traffic networks are touching, there is a special risk potential involved. For safely crossing one of them, a safe stop of the other is indispensable. If a railway or road overfly is not possible, level crossings are the only way of crossing these traffic routes.
We carry out planning, coordination and realisation, in order to enable accident-free crossings, taking into account the various local requirements and technical framework conditions. When it comes to construction, we put into practice harmonious connections to the surroundings, as well as the direct works in the area of the tracks.
Special and safe solutions for the underground represent a particular challenge especially in the area of the tracks. When choosing the right method, planning and building close to the tracks, it is important to pay special attention to the framework conditions. With our experience and ideas, we jointly develop the suitable concept for tracks with little need of shutdowns.
In the foundation soil there are often unexpected surprises to be found, like for ex. ground water, rocky underground or even areas where there may be warfare materials in the ground. The teams of LEONHARD WEISS can quickly and flexibly react to such surprises with their very up-to-date equipment and find possible alternatives. The development of special solutions and new methods is one of the specialities of our portfolio of performances.
Catenary systems serve the climate-friendly actuation on the tracks. There are, however, high voltages and forces involved. For this reason, the catenary systems require a high stability. Only by means of our solid foundations and masts the basis for the installation of electrified railway lines is created.
The portfolio of LEONHARD WEISS includes several variants of catenary foundations and masts, which can be specially adapted to the requirements of the route.
The prevention of the breaking out and spreading of fires is an essential assignment of constructional fire protection. The required measures in this field are being developed continuously.
Thanks to our many years of project experience, our portfolio not only includes the simple fire protection based on constructional methods, but also the mastering of more complex challenges in this field. As a professional partner we take on assignments in connection with all aspects of fire protection for you – from reliable statements, over safe installation up until the professional documentation of the measures.
LEONHARD WEISS only uses thoroughly chosen materials and closely cooperates with the respective manufacturers. Thanks to the installation of tested and certified systems we assure high quality.
Some of the central challenges of tunnel construction are the cramped spatial conditions, elaborate logistics, additional ventilation with fresh air and construction work during traffic operation. Nevertheless, existing infrastructure buildings must regularly be adapted to the new safety requirements and demand technical retrofitting from time to time.
For this reason, it’s an important assignment, to adapt existing infrastructure buildings to new requirements, for example by means of tunnel safety lighting or signposting of escape ways. LEONHARD WEISS offers these performances and others, in order to guarantee a safe operation in the structure.
The experts of LEONHARD WEISS look back on decades of experience in retrofitting tunnels, laying cables in existing structures, erecting escape ways, producing the minimum clearance profile for the electrification or assembly points and fire-fighting water tanks.
Signals and traffic lights are indispensable control elements in railway and road traffic and ensure optimum safety of the road and rail users. A safe signal foundation is thus even more important.
With TECDOWN, LEONHARD WEISS has proven its capacity of innovation: in addition to a short period of construction with minimum effects on operation during production, this system facilitates an adjustment of construction tolerances, the circumvention of local obstacles, as well as the adaptation to various construction ground conditions. This enables a high accuracy of fit for later use, as well as a long lifecycle, thanks to the construction which is resistant to settlement and free of maintenance. Alternatively, we construct monolith foundations in various sizes.
Our experienced team expertly and flexibly adapts to always new framework conditions of projects and offers individual solutions in any field. The curiosity to discover new possibilities motivates us to the highest performances.
No matter, if steep railway lines, high voltage or pressure in case of through-press pipes are concerned: together with you we will think further and develop projects made to measure. Experience has proven that pilot projects are very valuable to tackle new challenges and further innovations.
In this think-tank we have already developed very diversified methods, some of which are to be found in our current portfolio of core performances.
