Digital Twins for Rail Training: Bringing Depots and Stations into VR
Digital twins allow rail organisations to recreate depots, stations, platforms and operational spaces in VR. This gives staff a safe way to learn site-specific hazards, practise route familiarisation and rehearse procedures before entering the real environment.
What Is a Rail Training Digital Twin?
A digital twin is a virtual representation of a real-world place, asset or process. In rail training, this could mean a 3D version of a depot, station, platform, control room, rolling stock interior, maintenance bay or trackside access point.
The aim is not always to model every detail perfectly. The level of realism should match the training objective. For basic induction, a stylised environment may be enough. For site-specific familiarisation, the digital twin may need accurate routes, signage, restricted areas, equipment positions, evacuation paths and hazard zones.
Digital twin thinking is increasingly relevant in rail. HS2 has described how virtual reality, real-time monitoring and sensor data can support infrastructure reliability, including assets such as rails, bridges and overhead power lines.
Why Digital Twins Are Useful for SOP Training
Rail SOPs are often closely tied to location. The correct procedure may depend on where a person enters the site, which route they take, what equipment is nearby, which access points are authorised and how the station or depot is laid out.
A digital twin helps learners understand the environment before they arrive. Instead of reading a map or watching a video, the trainee can physically move through a virtual version of the site and practise the required behaviour.
Digital twin VR training can support:
Depot and station induction.
Safe walking route familiarisation.
Platform and concourse layout awareness.
Emergency evacuation route practice.
Restricted area recognition.
Rolling stock access training.
Contractor and visitor familiarisation.
Scenario-based incident response practice.
Site Familiarisation Without Site Disruption
Bringing learners onto live rail sites can be difficult. Depots are operational environments. Stations are public spaces. Some areas cannot be accessed without supervision, and certain scenarios cannot be staged safely.
VR reduces that constraint. Learners can explore a virtual station or depot before they attend in person. This can make real-world familiarisation faster and safer because the learner already understands the layout, key hazards and expected behaviours.
This approach is particularly valuable for large transport networks that need to onboard staff, contractors or apprentices across multiple locations. Each site can have its own VR familiarisation module, while the core training structure remains consistent.
How a Digital Twin Rail Module Could Work
A rail digital twin module should be practical, structured and linked to clear learning outcomes. It might begin with guided exploration, then progress to independent decision-making and assessment.
Example digital twin training journey:
Orientation: The learner enters a virtual depot or station and is introduced to the layout.
Route familiarisation: The learner follows approved routes to key locations.
Hazard recognition: The learner identifies restricted zones, moving assets, electrical risks and passenger flow issues.
SOP practice: The learner completes a site-specific procedure, such as accessing a maintenance area or responding to a platform incident.
Scenario variation: The system introduces a blocked route, crowding issue or asset movement.
Assessment: The learner is scored on route choice, hazard awareness and procedural compliance.
Using Scanned Environments and 3D Modelling
There are different ways to create a digital twin for VR training. The right approach depends on the required fidelity, budget, timeline and training purpose.
Common creation methods include:
Reference photography: Useful for modelling a representative environment.
CAD or BIM data: Valuable where accurate geometry already exists.
Photogrammetry: Useful for capturing visual detail from real locations.
Gaussian splatting or scanning: Helpful for realistic site capture and familiarisation.
Hybrid modelling: Combining scanned backgrounds with interactive 3D assets.
For training, the important question is not “how realistic can we make it?” but “what does the learner need to recognise, practise and remember?” A good digital twin supports learning rather than overwhelming the trainee with unnecessary detail.
Digital Twins for Passenger Movement and Station Planning
Digital twin technology is also relevant to passenger movement. The UK Transport Research and Innovation Board has highlighted a project using a digital twin platform to visualise passenger movements and behaviours in railway stations, with the aim of monitoring station performance.
For VR training, similar thinking can be applied to staff preparedness. A station team could practise crowd control, accessibility support, disruption management or emergency evacuation inside a station environment that reflects real passenger flow challenges.
Why Bespoke Matters
A generic rail environment may be useful for broad awareness, but site-specific training is where digital twins become especially powerful. A bespoke VR module can reflect the client’s own:
Station or depot layout.
Walking routes and access restrictions.
Local signage and terminology.
Emergency routes and assembly points.
Rolling stock types and asset locations.
Operational SOPs and escalation procedures.
Spark Emerging Technologies can create bespoke VR digital twins for rail and transport training, using the right mix of scanning, 3D modelling, interaction design and procedural logic. Spark’s work with Network Rail shows how realistic railway environments can be used to support safe working practice training in VR.
Conclusion: Turning Real Places into Safer Practice Spaces
Digital twins give rail organisations a practical way to bring real depots, stations and operational spaces into VR. Staff can learn the layout, understand site-specific hazards and practise procedures before they step into the live environment.
For rail, transport and mass transit operators, this can improve induction, reduce disruption, support contractor familiarisation and create a more consistent approach to site-specific SOP training.
