SISS maintenance across the GWR network
Planned and corrective maintenance of CCTV, CIS, PA and Help Points at managed stations and depots, with a customer helpdesk, CCTV downloads and the asset database.
Asset Management and Lifecycle Support
Station asset management: asset registers, location hierarchy, asset identity, component structure, maintenance history, spares and obsolescence support.
Requirement
An estate of station equipment needs an accurate record of what exists and where, a structure that a fault can be matched to, and early warning of what is going out of support.
TDM keeps the asset record that maintenance and monitoring work from: what exists, where it is, and what has been done to it.

Maintenance records
On a Help Point maintenance contract, every Help Point had an asset record, and every planned and corrective visit was logged against it. The records supported PPM reporting, engineer audits and the review meetings that governed the contract.
Spares are part of the same support: TDM holds Help Point spares in Crawley and supplies replacement electronics boards.
Registers and identity
TDM’s asset data work keeps apart where an asset is, as service location and sub-location; what it is part of, as system, subsystem and component; and which asset it is, as a master record with a descriptive engineering tag. Maintenance and condition history is held against each record. Clean structure is what lets a monitoring event or a reported fault land on the right asset.
Live operations
TDM’s asset and maintenance platform is live. It records assets, locations and products, supports mobile engineering activity and digital inspection worksheets, and provides a locations map, dashboards and automated escalation.
