Mission

TDM keeps the systems UK railway stations depend on running, from design to long-term maintenance, so passengers stay informed and can reach help, and staff can act on what they see.

What TDM delivers

Station systems, and the services that carry them through.

Survey and design, consents and assurance, installation and commissioning, maintenance, asset support, and documentation and handover carry each system through.

  • CCTV

    Railway station CCTV and video surveillance systems (VSS): replacement, analogue to IP migration, commissioning and maintenance on the operational railway.

  • Customer Information Systems

    Customer information system (CIS) display renewal and enhancement, with the civil, electrical and mounting works that go with it.

  • Help Points

    TDM's own railway station Help Points, supplied, installed, upgraded, commissioned and maintained across whole networks.

  • Public Address

    Station public address surveyed, designed and maintained within station information and security system (SISS) scopes.

  • Operational Telecoms

    Railway telecoms for operations: operational voice and telephony, SIP and VoIP, GSM-R and radio, Help Point communications and Public Address integration, on TDM's NIS platform.

  • Control Rooms

    Video walls and source integration, CCTV recording and video management, and Help Point call handling for rail control rooms.

  • Data and Network Infrastructure

    Station data and network infrastructure, from LAN and fibre cabling to switches, cabinets and containment, delivered within station system projects.

How TDM works

Survey, design, prove, install, commission, hand over.

  1. 01

    Survey

    Dilapidation and intrusive surveys record the existing estate, connectivity, electrical capacity, containment and access constraints.

  2. 02

    Design

    Reference design fixes the scope. Detailed design produces the arrangements, schematics and risk assessments the installation needs.

  3. 03

    Configuration and proving

    Systems are built and tested in TDM's Crawley workshop before they go to site.

  4. 04

    Installation

    Civil, electrical, cabling and equipment installation around a working railway.

  5. 05

    Commissioning

    Testing against the Inspection and Test Plan, commissioning and Entry into Service.

  6. 06

    Handover

    O&M documentation, as-built and cable records, test results and asset information.

Workshop proving before site workSystems are configured and proven in the Crawley workshop, then installed and commissioned on site, so site work on the operational railway is installation and commissioning.Crawley workshopSiteInto serviceConfigure and proveVMS, recorders, network equipmentInstallPossessions and platformsCommissionHand over into serviceFaults found on the benchCrawley workshopSiteInto serviceConfigure and proveVMS, recorders, network equipmentInstallPossessions and platformsCommissionHand over into service

Workshop

Configured and proven before site.

On CCTV and station systems projects, TDM configures and proves video management systems, recorders, cameras and network equipment in its Crawley workshop. That reduces the work carried out in possessions and on platforms, and faults are found on the bench.

Coordination on a station schemeTDM leads delivery and coordinates with the customer, Network Rail assurance and other suppliers. Consents, including design acceptance and Landlord's Consent, run in parallel, and equipment the customer supplies is built into one programme.Coordinated withDeliveryOutcomeCustomerCustomer-supplied equipment built inNetwork Rail assuranceDesign acceptance and Landlord'sConsentOther suppliersCoordinated into the programmeTDMDelivery leadOne programmeConsents run in parallelCoordinated withDeliveryOutcomeCustomerCustomer-supplied equipment built inNetwork Rail assuranceDesign acceptance and Landlord's ConsentOther suppliersCoordinated into the programmeTDMDelivery leadOne programmeConsents run in parallel
