TSFA GmbH (Turnout Sleeper FactoryAustria) was founded in 2008 as a joint venture between Kirchdorfer Fertigteilholding GmbH and voestalpine Turnout Technology Zeltweg GmbH. Thanks to the decades of experience of both companies in the respective specialist area of railway infrastructure business the development and production of concrete turnout sleepers and the provision of complete turnout systems the concrete turnout sleepers can be optimized and further developed in the overall system. With the founding of voestalpine Railway Systems GmbH in 2020, TSFA is now part of the world s leading provider of system solutions for rail infrastructure. TSFA offers different types of high quality, prestressed concrete turnout sleepers, optionally with under sleeper pads and fastening systems. The declared products are prestressed concrete parts of different size and design for use as concrete turnout sleepers. The concrete turnout sleepers support and keep the rails and turnout components in the correct position and transfer the loads to the track superstructure. The concrete consists of • prestressed steel, • cement (hydraulic binder), • sand and gravel of different grain sizes (aggregates) • water and • admixtures and additives. Castin plastic parts of a dowel fastener form the anchor for attaching the rail fastening systems. Depending on the design of the fastening system, additional reinforcement elements such as end brackets or dowel reinforcements made of steel are required. Depending on the requirements, the concrete turnout sleepers may be alternatively supplied preassembled with under sleeper pads, ribbed base plates or fastening material for rails. A possible preassembly takes place in a separate work step within the plants and is not taken into account in this EPD.
