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 testbeds, 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 signaling 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.
