Rail communication

INDUSTRY EXPERTS DAMM provides digital radio and broadband communications solutions backed by expert advice to clients in the transportation industry, who depend on always-available connectivity

Failsafe reliability for voice and data communication

Let’s make this easy. When you increase reliability, you increase your ability to deliver uninterrupted, safer service.

Whether it's an urban rail, light rail or monorail system, you want to digitize and future-proof your transport communications with a mission-critical radio communication system. DAMM combines decades of leadership with cutting-edge digital radio and broadband communications to create a simple, yet reliable solution that is easy to deploy and maintain. 

Go hybrid to future-proof your rail communication system

A conductor faints. A train starts driving with a door still open. At times like these you know how important critical communications can be.

Stay agile with DAMM. That way you can easily link train operations with passenger announcement, security and signalling systems to improve performance and enhance security. Go hybrid with the 4-in-1 DAMM MultiTech Platform that offers TEDS, TETRA, DMR and analog in one base station.

Enhanced by partnerships

We partner with system integrators and experts to give you the solution and support needed to make your rail communication system better. By working closely with partners from the start, we ensure easy integration into complex projects. With an open API, DAMM provides easy integration of customized applications too.

Efficient collaboration with system and project management increases the likelihood that projects will be completed on time.

A promise of safety

Learn how DAMM is the reliable choice for critical communication no matter if it is underground, highly densely populated areas or rural, harsh remote areas.


DAMM offers three major ways to save: Plug-and-play design, lower operating costs and lower maintenance costs. DAMM TetraFlex® offers low CAPEX and OPEX by allowing you to better utilize people and resources while improving the reliability of service and levels of safety.

1. Plug-and-play design

Plug-and-play means easy and seamless design and scaling of networks, which allows you to think big, start small and scale fast. Our flat decentralized IP architecture and intuitive software enable effortless, self-configuring site expansion. You can add or integrate all network components, including base stations, dispatchers, network management facilities, and external gateways at any time, even while the system is in operation.

2. Lower operating costs

DAMM offers plug-and-play simplicity for easy setup and fast deployment. The compact design of the DAMM outdoor base station enables direct mounting on antenna masts, buildings and tunnels, reducing feeder loss and installation costs considerably. Both the indoor and outdoor base stations offer extremely low power consumption, and thanks to the IP65 encapsulation, the outdoor base station doesn't need any external air-conditioned housing. DAMM TetraFlex is developed with flexibility and user-friendliness at the core, saving substantially on training and project costs.

3. Lower maintenance costs

DAMM’s rugged base stations also keep maintenance costs down. Even for operations in extreme ‑50°C to +50°C temperatures, our base stations keep on working. Thanks to the low power consumption our base stations also generate minimal heat, and together with the IP65 encapsulation this eliminates the need for cooling fans that require maintenance. Furthermore, redundancy means that maintenance can be done without shutting down operations, ensuring an efficient railway operation.

TEDS, TETRA, DMR and analog core-connected in one platform, which is future-ready and easy to integrate with both existing and new systems.

Four technologies truly core-connected in one powerful platform – without any gateways or bridges. The DAMM MultiTech Platform solution unites TEDS, TETRA, DMR and analog into one platform so that you can improve productivity with a future-proof investment while also making it possible to get more channels without extra hardware.

DAMM MultiTech Platform is ideal to meet the challenges in the rail and metro industry. The MultiTech Platform enables you to:

  • Meet the need for more data by using TEDS for train control or pushing data to the train information system, still within the same secure and independent communication platform.

  • Reduce the number of base stations and extend track-side coverage utilizing VHF in remote areas and high power output. Options include 25W TETRA and/or 50W DMR.

  • Save installation and operation costs
    with a rugged, compact outdoor base station ideal for track-side installations. The BS422 is certified for track-side installation due to EN 50121-4 approval. The BS422 offers best-in-class power consumption, lowering operational costs, and enabling alternatives for energy supply, like solar power.

  • Easily perform remote management with one application for all technologies. Full remote manageable base stations across technologies, in hybrid operation, eliminating the need for on-site service, and making it ideal for remote sites

  • Ensure improved tunnel coverage and improved node synchronization
    , eliminating the need for GPS coverage by utilizing IEEE 1588 for node synchronization. Alternatively use the simulcast option of the BS422; same network management platform, full output power and sensitivity.

DAMM solutions are built to be resilient. Take our outdoor base stations. These IP65-protected solutions are the only base stations certified to work alongside tracks.

DAMM decentralized systems have no single point of failure thanks to full redundancy throughout the network. This is vital, especially if the network is interfaced with your public announcement and passenger information systems and the train’s computer. It will not let you down in day-to-day operations. And it will not fail in cases of emergency. Even after years of service, it will never let you down. If one base station goes down, your operations retain full coverage.

Whether you are keeping the trains running on time or dispatching employees, you can rely on DAMM for uninterrupted communication. It empowers you with the speed and reliability you need to keep operations running smoothly

You can even send group messages to alert everyone with a need to know, including external parties such as ambulance or police services.

DAMM networks keep everyone, from the gound to trains, in sync. The decentralized DAMM design integrates TEDS, TETRA, DMR and analog into one platform. Furthermore, DAMM's built-in applications and compatibility with third-party equipment make it easy to adopt new software and integrate with other systems.

The truly decentralized architecture lets you use any radio terminal or TETRA over LTE/WiFi, giving you a high level of ​flexibility. You can also upgrade, add new subscribers, or move your system without shutting down the network – a crucial feature to operators, who cannot afford passenger service downtime.

The fully IP-based technology used by DAMM TetraFlex makes it possible to create integrated communications across multiple stations, logistics & maintenance facilities, depots and centralized operation control centres.

The fully redundant system can support any capacity, from small to large railway systems and metro infrastructures. All information is replicated to all sites, enabling uninterrupted call and data traffic if one or more sites lose connection with the rest of the network.

The flexibility of a DAMM solution also extends to the ability to use a combination of indoor and outdoor base stations. Furthermore, DAMM's outdoor system has gained EN 50121-4 certification, which will be available upon request.

Why Western Railway in India chose a DAMM solution
