Schweerbau

What Schweerbau does

Schweerbau GmbH & Co. KG is a family-owned German railway construction and infrastructure services company founded in 1929 by Heinrich Schweer in Stadthagen, Lower Saxony. The company provides specialized track construction (Gleisbau), rail treatment (Schienenbearbeitung), civil engineering (Tiefbau), welding technology (Schweißtechnik), overhead line systems (Oberleitung), sewer inspection, and metro/tram services to public-sector and enterprise clients — primarily Deutsche Bahn, urban transit operators in Hamburg, Berlin, London, and Paris, and German municipalities and the Bundeswehr.

The company's underlying technology is a fleet of approximately 60 specialized heavy machines including tamping machines, ballast cleaning machines, formation rehabilitation machines, renewal trains, ballast ploughs, and rail grinding machines. Schweerbau holds proprietary intellectual property in a patented dust-free and spark-free rotational planing device (Drehhobel) for rail maintenance and is the only operator worldwide using all four conventional rail treatment methods (grinding, milling, planing, and rotational planing), as well as the only German firm certified to perform BÜG (besonders überwachtes Gleis) grinding for noise-reduced rail surfaces.

Schweerbau earns revenue through project-based service contracts secured via public tendering and prequalification frameworks, principally Deutsche Bahn AG prequalifications for track superstructure and overhead line systems (valid through 2028). Distribution is direct enterprise field sales; pricing is project-specific and not publicly disclosed. The firm operates from its Stadthagen headquarters, four German branches (Berlin, Bochum, Leipzig, Magdeburg), and international offices in Wrocław (Poland), Opava (Czech Republic), and London (UK). Schweerbau holds ISO 9001/14001/45001/50001, RISQS, DVGW, DQB, and DB Netz AG welding approvals, and operates an internal Moodle-based training platform to develop vocational skills for its approximately 900-person workforce, which has grown roughly 9x since 1990.

Core offering

Schweerbau is a family-owned railway infrastructure services company that delivers track construction, rail treatment (grinding, milling, planing, rotational planing), civil engineering, sewer inspection, rail welding, and overhead contact line systems. Services are executed using a fleet of 60+ specialized rail construction machines and approximately 900 employees across Germany and Europe. Primary customers include Deutsche Bahn, urban transit operators, municipalities, and the German Armed Forces.

Product overview

Schweerbau is a family-owned railway construction and infrastructure services company founded in 1929. Its offering consists of a unified portfolio of specialized services—rather than a software platform with discrete modules—centered on rail and civil infrastructure. The core services are: Gleisbau (track construction), Schienenbearbeitung (rail treatment), Tiefbau (civil engineering), Kanalinspektion (sewer inspections), Schweißtechnik (welding technology), Oberleitung (overhead line systems), and dedicated metro/tram services for urban rail networks. These services are delivered using Schweerbau's owned fleet of heavy machinery (tamping machines, ballast cleaners, rail grinding machines, renewal trains) and supported by an internal Moodle-based online training platform and a rail service facility in Gelsenkirchen-Horst Nord.

Products and services

• Gleisbau (Track Construction) Full-service track construction covering maintenance of rails, sleepers, ballast, and formation for all line speeds, supported by a fleet including six tamping machines, ballast ploughs, ballast cleaning machines, a formation rehabilitation machine, and a renewal train. Delivered to rail network operators such as Deutsche Bahn under DB AG prequalification.
• Schienenbearbeitung (Rail Treatment) Comprehensive rail treatment using all four conventional methods — grinding, milling, planing, and rotational planing — including the dust- and spark-free rotational planing invented by Schweerbau. The company is the only one in Germany authorized to grind using the BÜG (specially monitored track) procedure for noise reduction on rails.
• Metro- und Straßenbahn (Trams and Underground Railways) Expert rail treatment and repair services for metro and tram systems in cities such as Hamburg, Berlin, London, and Paris, utilizing specialist low-emission machinery with filters and dust extraction. Battery-operated, zero-emission tunnel machines are in development.
• Tiefbau (Civil Engineering) Civil engineering services encompassing sewer construction, road building, land development, and special projects such as rain retention basins and special shaft structures, as well as construction and improvement of plazas, pavements, and bicycle paths.
• Kanalinspektion (Sewer Inspections) Sewer inspection and maintenance services including sewer cleaning, sewer inspections, and sewer leakage tests, with the equipment, expertise, and certification to meet the SüwV Kan statutory self-monitoring requirements.
• Schweißtechnik (Welding Technology) Rail welding services covering superstructure joint welding, aluminothermic joint welding (AS-SkV, AS-SkV-L, AS-LSV), arc joint welding, and rail/point maintenance using welding and grinding technology. All welding on rail materials for operational tracks is conducted in accordance with DB AG guideline 826.1020 in class 1.
