Platform21

Accelerate Digital Trackside Development with Platform21 Developing and certifying digital trackside infrastructure is traditionally slow, expensive, and complex. Testing new object controllers, interlockings, and safety-critical field elements often requires access to live systems or expensive test beds, making early-stage validation difficult and delaying integration. Certification cycles are prolonged by fragmented test processes, limited automation, and the high cost of reproducing real-world signalling conditions. Platform21 accelerates this process by providing a flexible test harness that supports both Software-in-the-Loop (SiL) and Hardware-in-the-Loop (HiL) testing in a remotely accessible, distributed, and highly adaptable manner. It simulates key elements of trackside infrastructure with high fidelity, enabling system developers, infrastructure managers, and assessors to validate functionality, automate test procedures, and iterate designs throughout the complete testing pyramid. This shortens time-to-approval, reduces project risk, and brings new digital solutions to operational readiness faster. Specification Browser Access up-to-date EULYNX documentation and specifications in an easy-to-read format. Quickly check for deltas between EULYNX releases. And create, share and consume links that point to exact locations in the specification for traceability. Simulators-to-Go Across Baselines Take on complex interoperability and system test cases with EULYNX- and NeuPro-compatible simulators for all specified interfaces. Use our qualification packages (available starting from Baseline 4) to make tool validation a breeze. Support for EULYNX B2, B4R1, B4R2, B4R3, B4R4 and national baselines SCI-LS, SCI-LX, SCI-P, SCI-ILS, SCI-CC, SCI-IO, SCI-LC, SMI, SDI and SSI testing Easy Configuration Management Create configurations for single subsystems. Combine subsystems of the same or even different baselines to interlockings. Export configurations and re-import to recreate and share test conditions and demonstrators across teams, organizations and laboratories. Use artifacts in your CI-Pipeline to automate the process with our built-in configuration API. All simulator modules come as versioned, fingerprinted and verified artifacts Distributed Lab, Ready for Remote Control with Local Runtime Lacking space? Missing components? Borrow resources from other lab locations across the globe. Set up secure networks to test without borders and combine laboratory with field-test environments. Use our pre-qualified open source RaSTA stack from SBB. Worried about internet connectivity? Keep the execution environment, including the Platform21 runner and simulation modules local. No additional network delays, no security hazards. If remote control is not your use case, just keep everything air-gapped. Our simulation and observability APIs are still available on-site. Share and work on the same test setup with your team members. Always look at the same configuration – never worry about the current source of truth again. Take on complex interoperability and system test cases Keeping Pace with a Developing Specification EULYNX is under active development. Maintaining a simulator landscape, configuration management, interfaces, national adaptions and variants of your test environment for more than one baseline is challenging. A test setup validated against one release is not automatically valid against the next. The decisive question for a project is which of its existing setups a given change invalidates, and which tests have to be repeated as a result. Deltas tracked between releases as they are published Impact analysis against your existing test setups Always up-to-date with the latest baselines Security Evidence Alongside Safety Evidence Shared security services are specified alongside the signalling interfaces, and Europe’s Rail is establishing the corresponding security test cases. Demonstrating a secure implementation is becoming the same kind of repeatable, documented exercise as demonstrating a safe one. Together with our partner INCYDE, whose cyber security testbed automates testing against the EU-Rail catalogue for SSI, we produce security evidence on the same footing as safety evidence.
