Authority to Work Permit App & Web Portal
What is Permit+?
Permit+ is a purpose-built, cloud-based platform designed for light rail operators to manage the entire lifecycle of Authority to Work (ATW) permits – from application to approval, to live field activity and beyond.
Built specifically for the operational, safety and compliance demands of urban rail environments, Permit+ replaces outdated paper workflows with an intuitive, real-time, mobile-connected system – giving your control room, engineers, and third parties complete visibility and control over work on or near your infrastructure.
Why Permit+?
Legacy systems and manual processes can’t keep up with the complexity of today’s light rail operations. Permit+ gives operators the tools to enforce safety, streamline approvals, and gain complete visibility of work across the network – all in one connected platform, purpose-built for the realities of modern light rail.
Built for Light Rail
Not a generic workflow tool, Permit+ understands the nuances of track access, isolations, possessions, risk reviews, and control room safety processes.
Digital From Day One
A public-facing portal, internal review tools, and a field-ready mobile app work together to eliminate paperwork and miscommunication.
Live Worksite Intelligence
Track the live status of every active permit across your network, enabling control room teams to make informed operational decisions instantly.
Key Features
Structured Online Applications
Permit+ replaces guesswork and manual forms with a clear, consistent digital process. Applicants are guided through a structured workflow that captures the information you need – first time, every time.
Standardised online application forms with enforced structure
Secure payment system supporting card and invoice billing
Built-in document uploads for plans, diagrams, and supporting evidence
Engineer Review & Risk Mitigation
Take control of the review process with configurable rules, assignment tools, and structured safety assessments. Engineers can focus on risk, not admin.
Intelligent management and assignment based on application type
Customisable risk mitigation steps applied per permit
Full audit trail of decisions, changes, and reviewer input
Permit Issuing, Rescinding & Extending
Permit+ gives operators full lifecycle control over every permit. Whether issuing a new permit, updating existing conditions, or withdrawing access, the platform ensures changes are logged, traceable, and communicated instantly.
Issue permits with clear conditions and embedded risk mitigations
Rescind or invalidate permits when works are delayed, or non-compliant
Extend permits easily with change tracking and notifications
Interactive Map & Calendar
Visualise upcoming and active works in space and time. The built-in calendar and mapping tools help operators plan smarter, avoid clashes, and make the most of scheduled access windows.
Geospatial and schematic views of permits across the network
Date-range filters, application type selectors, and location targeting
Group permits visually to plan for possessions and coordinate works
Field-Ready Mobile Access
Bridge the gap between control room and field with a robust, purpose-built mobile app. Everyone on site sees the same data, updated in real time.
Review permit details and supporting documentation on-site
Request to start or end works via mobile with push notifications
GPS-linked “proof of permit” and in-field validation
Live Permit Activation
Know the difference between a permit that’s issued and one that’s actively being used. With live activation, the control room maintains oversight of all ongoing works at any given time.
Mobile or desktop-triggered start and stop requests for on-site activity
Control room approval required to begin or even complete works
Real-time map of active permits with status tracking
Smarter Map Visualisation
Permit+ uses intuitive marker icons to show exactly what’s happening across the network. At a glance, operators can distinguish between applications and issued permits, see which works require an isolation, and track whether a permit is active or live.

Testimonials
Why Edinburgh Trams chooses Permit+
Marilena Papadopoulou
Head of Projects and Renewals - Edinburgh Trams
"Permit+ has fundamentally modernised how we manage access to the tram infrastructure.
“The shift from paper-based systems to a fully digital platform has allowed us to track every permit application in real-time, with a full audit trail of risk assessments, approvals, and on-site activity. The introduction of live activation and deactivation via the mobile app has significantly improved our field-to-control room coordination.
”Engineers no longer have to rely on manual phone-ins or email chains - we now have a structured, enforceable workflow that ensures work starts and ends with the correct authorisations in place.
“From a planning perspective, the live map and calendar views let us quickly assess network availability and avoid conflicts. The platform’s flexibility in grouping permits around isolations or major works has also helped us streamline possessions and reduce service interruptions.
”Permit+ has become a critical operational tool for us that we continue to promote within our industry as it ensures that access to the tram infrastructure is managed in a safe and controlled way."
