Selection Criteria for Our Partners
When selecting our manufacturers, technology partners, and suppliers, we rely on clear standards. Quality, technical expertise, international experience, high delivery capability, and long-term trusting cooperation form the basis of our actions. This ensures that our customers receive reliable products, sustainable solutions, and a partner they can consistently rely on.
Your Added Value Through Our Network
Our partner network provides access to high-quality components and resilient procurement strategies – far beyond simple purchasing.
Access to high-quality components
Through our partnerships with internationally recognized manufacturers, we offer our customers access to quality-tested components that meet all relevant standards and approvals – without the need for their own complex qualification processes.
Resilient procurement strategies
Our network enables alternative sourcing channels, framework agreements, and storage options. This ensures availability even in the event of supply bottlenecks, product discontinuations, or geopolitical challenges.
Technical depth & consulting
Collaboration with specialized manufacturers allows us to clarify technical queries directly – from material certificates and conformity proofs to installation recommendations.
Single point of contact
Instead of negotiating directly with many manufacturers, you manage a central procurement partner through ASTRA – who coordinates, bundles your inquiries, and delivers qualified offers in a short time.
Driving Innovation Together
Our technology partners are an important part of our solutions. Through close collaboration with leading technology companies, we combine innovative systems, modern software, and forward-looking technologies into powerful overall solutions. This creates the foundation for efficient, reliable, and sustainable applications in rail transport.
