EDM’s NX Digital Signalling Simulator (DSS) is a powerful, immersive training solution that realistically models the operations of rail signalling systems. Designed to simulate normal and degraded working conditions, the DSS enables Signallers to gain experience in managing complex rail networks in a safe, repeatable and highly flexible training environment.
Built on over 30 years of simulation expertise and powered by EDM’s proprietary CASCADE software, the DSS supports a wide range of real-life training scenarios, from standard operations to high-stress emergency situations.
Key features include:
Full simulation of NX panel functionality and interlocking
Realistic train movement and control across a simulated rail network
Uploadable timetables and train pathing from Rail Validation Systems
Instructor and trainee consoles with scenario creation, recording and playback
Safety Critical Voice Communication simulation and review
Operational communications via concentrator simulator
Simulated level crossing procedures, CCTV systems, and SPAD incidents
Compatible with Westcad and EDM’s GSM-R simulator
Training benefits:
Safe environment to simulate and resolve real-world rail incidents
Degraded working, points failures, and service disruptions can be introduced
Trainees build confidence in incident response and operational consistency
Recording and playback support detailed feedback and KPI analysis
Supports self-teach mode and classroom training environments
Scenario flexibility:
Generic track layout (Gatestown) for standardised exercises
Custom track schemes can be modelled using the track edit application
Pre-programmed event timetables and faults can be inserted offline
Enables creation of diverse and repeatable lesson plans and exercises
With the DSS, rail training centres and operators can train signallers to handle everything from routine movements to high-pressure fault resolution — all without impacting real-world operations.
