United, the companies voestalpine Signaling Sainerholz GmbH and voestalpine Signaling Austria GmbH form the Competence Unit, “Drive, Locking, Detection & Signaling" (CU DLD/S) in the voestalpine Railway Systems.

voestalpine Signaling Sainerholz GmbH CU DLD/S – core-competences

With the expertise of over 375 (in 2023) specialists in the CU DLD/S it has made it possible for us to develop, produce and assemble efficient solutions with and for railway infrastructure companies for over 35 years. Depending on the requirements, the products can be further developed individually in order that we can put customer needs first.
There are important factors for the safety of rail transport – above all, they must work precisely, be reliable and robust as well as withstanding extreme loads.

Worldwide projects on a large and small scale, as well as maintenance and repair work on running systems, are developed, coordinated, produced, installed and supported ex works.
With more than 26,000 point machines, locking and signaling systems in operation around the world, the solutions from voestalpine Railway Systems CU DLD/S reliably offer consistency for railway infrastructure operators and their passengers: PERFORMANCE ON TRACK®.

  • Maximize track availability with our product range.

  • The Railway Systems Academy has been offering a global training network since 2020 and stands for comprehensive professional development and knowledge advantage in the railway sector. The expert product know-how as well as maintenance training, is imparted at the training centre on the Sainerholz campus by our own service technicians, with lots of practical experience and passion for their profession. This enables customers to maintain the installed products with their own team and optimise technical availability.

    Providing unique added value for knowledgeable advantage and reliable availability of products in times of a shortage of skilled workers, the training programme offers a wide range of training courses. This offers an additional value, allowing customers to benefit from expert knowledge and practical experience in addition to the product, service and system solutions.
