From a Single Display to a Network-Wide Programme

TDM’s information display solutions encompass the full range of passenger and operational display systems used in critical infrastructure environments, from Customer Information System displays showing real-time train running information, to dynamic operational displays in control rooms and command centres, to wayfinding and messaging screens across complex multi-site estates.
Every installation we deliver is designed around the specific environment it serves. Because no two sites are identical, our approach begins with detailed surveys that inform tailored mounting solutions, connectivity designs, and equipment specifications. As a result, whether we are working in a listed heritage building, a live operational station, or a purpose-built control room, we design a solution that works within those constraints, rather than asking the environment to fit a standard template.
Since 2000, TDM has been delivering information display solutions across the UK for infrastructure operators with some of the most demanding requirements in the sector. Moreover, our in-house design and manufacturing capability, including custom mounting brackets and columns manufactured at our Crawley facility, means we can tailor every installation to its environment. Consequently, our customers avoid the delays and cost uncertainty that third-party fabrication typically introduces.
What we deliver
End-to-End Delivery, Every Time
TDM manages every stage of an information display deployment, from initial site survey and system design through to installation, commissioning, and ongoing maintenance. Because we handle the full lifecycle in-house, our customers have a single accountable partner from the first conversation to the last maintenance visit.
TDM has delivered CIS systems across major network hubs, rural stations, and heritage environments. Specifically, this includes Infotec displays integrated with 4G connectivity where fixed network infrastructure is unavailable. As a result, operators get reliable real-time passenger information without costly civil engineering works.
Design and integration of display systems for operational control rooms and command centres, including video walls, operator workstation displays, and large-format screens for situational awareness and network management. TDM has delivered control room display solutions in collaboration with leading technology partners including Barco, acting as systems integrator for complex operational environments.
Every mounting solution TDM delivers is engineered specifically for its environment, designed and manufactured in-house at our Crawley facility. Consequently, every mounting solution is engineered specifically for its environment, accommodating heritage constraints, platform geometry, structural requirements, and control room configurations that off-the-shelf solutions cannot address. This capability removes a common point of programme delay and cost uncertainty.
Information display systems require reliable connectivity to function effectively. Where fixed network infrastructure is absent or impractical, TDM therefore designs and implements alternative solutions, including 4G-enabled displays and point-to-point Wi-Fi bridges. Consequently, operators avoid the cost and disruption of extensive civil engineering works entirely.
All TDM information display installations are specified to meet applicable accessibility standards. In particular, this includes Audio Frequency Induction Loop (AFIL) and Ampetronic induction loop panel installations for hearing aid users. Additionally, display specifications meet visibility and legibility requirements for passengers with visual impairments.
Long-term reliability depends on what happens after installation. TDM provides planned preventive maintenance, reactive support, and system upgrades for information display infrastructure throughout their operational life. TDM provides full O&M documentation at project handover and offers long-term maintenance partnerships to keep systems performing reliably throughout their operational life.
Why TDM
What Sets TDM Apart
TDM designs and manufactures tailored mounting brackets and columns at our Crawley facility. Rather than relying on third-party fabrication, we produce tailored mounting solutions in-house. This reduces lead times and eliminates a common source of programme delay. Every installation fits its environment precisely, a capability that most contractors simply do not have.
TDM has delivered information display solutions as a systems integrator, coordinating hardware, software, connectivity, and installation across complex operational environments. Our collaboration with Barco on a GWR control room project demonstrates this capability at the highest level. It combines leading Barco display technology with TDM’s installation and integration expertise to deliver complex operational environments.
TDM has delivered information display programmes spanning twenty or more stations simultaneously. These programmes coordinate surveys, consents, civil works, and installations across geographically dispersed locations, all without disrupting live operations. Consequently, operators commissioning large-scale network improvements can be confident in TDM’s project management depth.
TDM has delivered heritage-compliant display installations at multiple listed stations. In each case, we manage planning considerations alongside the technical delivery. Consequently, the customer does not have to coordinate two separate workstreams.
Where fixed network infrastructure is absent, TDM does not default to expensive civil engineering works. Instead, we design and implement alternative connectivity solutions, including 4G-enabled displays and point-to-point Wi-Fi bridges, that deliver the required functionality at a fraction of the cost and programme impact. Our Isle of Wight Island Line project demonstrated this approach in practice, eliminating the need for cable routes across island platforms that would have significantly increased both cost and disruption.
Where we work
Information display solutions are deployed wherever reliable, real-time communication with passengers or operational staff is essential. TDM’s experience spans a wide range of environments, each presenting unique installation challenges, heritage constraints, and connectivity requirements that our engineers are equipped to address.
CIS displays and integrated passenger information infrastructure are essential across railway stations, platforms, depots, and interchange facilities. TDM is RISQS approved and has delivered multi-site programmes across both major network hubs and remote rural stations.
Rail operations centres and network management facilities require large-format display systems, video walls, and operator workstation screens for real-time situational awareness. Acting as systems integrator, TDM works with leading display technology partners to deliver complex operational display environments.
Dynamic information displays in exposed coastal environments demand weatherproof housings and salt-resistant infrastructure as standard. TDM specifies and installs displays for passenger terminals and operational port facilities to exactly these requirements.
Production facilities and logistics sites requiring operational information displays to coordinate activities, deliver safety messages, and manage shift communications across large operational footprints.
Stations and facilities with listed building status requiring specialist finishes, heritage-compliant mounting solutions, and planning consent management. TDM has delivered compliant CIS installations at multiple listed buildings, including Salisbury, Chippenham, Maiden Newton, St Erth, and Brading stations.
Terminal and airside environments requiring high-visibility displays to deliver operational and passenger information across complex, high-footfall spaces with demanding visibility requirements.
High-security installations requiring information display infrastructure that meets stringent security and reliability standards, with integration into command and control systems where required.
Hospital campuses and education estates requiring clear wayfinding displays and operational information screens across large, multi-building environments serving diverse populations.
Our Five-Stage Delivery Process
Every information display project follows TDM’s five-stage delivery framework. Whether installing a single display or coordinating a multi-site programme across twenty stations, the same rigour applies at each stage. This is because thorough preparation is ultimately what makes reliable delivery possible, and what separates a well-managed programme from one that runs into avoidable problems on site.
Before any design work begins, TDM conducts detailed site surveys across all locations. During these surveys, we assess existing infrastructure, connectivity options, mounting constraints, heritage requirements, and accessibility considerations. As a result, every solution is grounded in a thorough understanding of the environment it will serve.
System design with full technical documentation, display specifications, tailored mounting designs, connectivity solutions, cable routing plans, and consent requirements identified for each site.
Managed installation by TDM’s own NICEIC-certified engineers, coordinated around your operational requirements and any consent conditions to minimise disruption to live operations.
Full system testing and sign-off, displays, connectivity, and accessibility features all verified against agreed acceptance criteria. Proof of concept validated in TDM’s Crawley systems suite before deployment where required.
Full O&M documentation provided at handover. Planned maintenance schedules and reactive support available to keep systems performing throughout their operational life.
