Digital Maintenance Gateway
Secure local and remote maintenance access through one audited route, with individual authentication and a common credential store across the fleet.
What it does
Digital Maintenance Gateway (DMG) improves security and efficiency when updating on-board and wayside systems by eliminating the need for dedicated service laptops and USBs. It provides a secure, managed point of access for existing maintenance applications.
Engineers use a familiar and consistent working environment. Local and remote access use individual authentication and can use multi-factor authentication, with the same audit trail. A common credential store across the fleet replaces shared per-vehicle accounts. Every session starts in a clean state and every action is attributable and auditable.
DMG supports controlled maintenance workflows across multiple units without exposing on-board systems directly to service laptops.
Key benefits
Reduce maintenance cost
Free skilled staff from managing service laptops with controlled distribution of firmware and configuration files. One engineer can update multiple units in a single shift, instead of one engineer per train per night.
Control access
Give named engineers controlled access to systems that cannot provide individual authentication themselves. This compensating control supports access-control evidence without modifying the underlying system.
Audit activity & monitoring
Full traceability of maintenance activity for compliance and fast diagnosis.
Close off common attack paths
Isolate insecure service laptops and remove USB transfer entirely.
Key capabilities
Secure remote access & authentication
Time-bound access is limited to specific assets and named engineers. MFA supports local and remote access, with a common audit trail.
Secure digital environment
A clean-state desktop session around your existing maintenance applications.
Controlled file distribution
Production, authorisation, installation, verification and monitoring form a controlled update workflow. A wayside repository supports code-signed software distribution, with synchronisation to the train and validation of the software. Separate production and authorisation roles control release.
Protects on-board systems
Isolates service laptops from on-board systems, removes USB transfer and prevents unauthorised applications from being added through the managed environment.
Session recording & audit
Recorded sessions support diagnosis and audit.
Works with wayside too
One maintenance approach across vehicles and infrastructure.
Control maintenance access
Digital Maintenance Gateway is the maintenance layer of The Secure Train: named users, multi-factor authentication, controlled update workflows and full audit records replace unmanaged service laptops.
