TMS – a traffic management system is one of today’s key technologies for sustainably increasing rail capacity and performance.

No later than the definition of the European Rail Traffic Management System (ERTMS), the traffic management system (TMS) was also identified as a central component of all rail infrastructure measures. Its aim is to significantly increase rail capacity and train timing, making networking and information processes more efficient and thus making rail transport more cost-effective and attractive – all without building additional tracks.

As a component – together with ATO, new interlocking technology and ETCS – a TMS enables up to 35% more capacity on existing infrastructure and thus expands the ability to respond flexibly to the growing demand in passenger and freight transport.

In order to leverage the full potential of technological possibilities, the expert TMS teams at NEXTRAIL work closely with our specialist departments for ATO, ETCS, digital interlockings, security and safety on an interdisciplinary basis.

NEXTRAIL actively participates in relevant, pioneering projects in the field of TMS and is therefore one of the leading knowledge carriers in this technology segment.

    The advantages of a TMS at a glance:
  • Support and (partial) automation of conflict detection and resolution through real-time disposition
  • Network-wide optimisation of train traffic based on defined rules and optimisation parameters
  • Integration of control and command in one system, operated by one person, eases ATO operation
  • Centralised information processes
  • Flexible networking of functionalities to increase efficiency
  • Efficient, user-centric user interface

ETCS – conceived essentially to simplify international rail traffic, digital train control systems are evolving into autopilot systems for greater safety and efficiency on the railways.

European Train Control System (ETCS) is a standardised train control system and a fundamental part of the European Rail Traffic Management System (ERTMS). With the introduction of ETCS Level 2 and wireless signal transmission (GSM-R) to the vehicles, ETCS is increasingly becoming a type of autopilot for rail.

ETCS monitors the train on the basis of precise positioning and predefined command parameters, enabling it to make exact decisions to keep the train safe, even at higher speeds. ETCS enables the transmission of information directly to the vehicle equipment. Driver’s cab signalling display/monitor eliminates the need for track-side signals and enables long-term savings in the installation and maintenance of railway operations.

The NEXTRAIL expert teams for the Stuttgart S-Bahn project have demonstrated the potential for increasing capacity on regional routes offered by ETCS Level 2 routes in conjunction with ATO and digital interlocking. The aim of the ETCS pilot project is to increase transport services by up to one million train kilometres per year. The holistic approach of the study included the following areas: engineering, certification, operations, planning, radio transmission, cost estimation and equipment strategy. The consideration was brought together in a cost estimate based on different equipment strategies. NEXTRAIL is actively involved in the relevant pioneering projects in the area of ATO over ETCS GoA 2 and driverless driving. And, it is one of the leading knowledge carriers in this technology segment.
    Your advantages with ETCS at a glance:
  • Increase capacity and safety
  • Highly available train control system
  • Elimination of track-side signals
  • Increased efficiency through networking with broad functionalities
  • Sustainable savings in installation and maintenance
  • Strengthens international freight and passenger transport

Digital interlocking – an essential component in reducing costs and increasing the competitiveness of railways.

Digital interlockings are the successors of electronic interlockings and replace various types and generations of existing interlocking systems with digital control and safety technology. In contrast to electronic interlockings, a digital interlocking transmits the control commands of the disposition digitally in real time over almost any distance via fibre optic cable to points and signals.

By standardising the interfaces, complete systems with components and technical solutions from various manufacturers can be implemented, continuously modified or expanded. Digital interlockings thus make a significant contribution to reducing time and costs. Whether installing, commissioning or maintaining railway infrastructure.

The expert teams for digital interlockings at NEXTRAIL have extensive experience from the industry and railway operation side and have excellent knowledge of the advantages and disadvantages of digital interlocking modules and components offered on the market and the adjacent systems. We define the best overall solution from a technical, functional and economic point of view on the basis of your requirements.

Within the framework of EULYNX, NEXTRAIL is working on the definition of future standards for the standardisation of signal components and signal interfaces.

    Your advantages of digital interlockings at a glance:
  • Sustainable reduction of time and costs
  • Free choice of components thanks to standardised interfaces
  • Intelligent, condition-based maintenance
  • Consistent separation of energy and data

Digital map and digital twin – precise digital infrastructure data as a core component in planning, construction and operation For greater efficiency and safety in the route network.

Topography and infrastructure in a digital mirror image – as a digital map or a digital twin. The digital map contains data on tracks as well as their environment and elements that are used directly for planning, project design, validation and configuration of railway systems. The digital twin for infrastructure data is an exact, digital spatial representation of reality and plays a decisive role, for example, in predictive and intelligent maintenance or operational simulation of current or future capacities Up-to-date and reliable digital infrastructure data is an essential core component in order to be able to safely operate high-frequency trains at optimum intervals on digitised routes. This is both during the planning phase and later on for the entire life cycle of the railway system.

In railway systems such as interlockings or TMS, this static infrastructure data from the digital map is linked to dynamic information such as train location, train speed, train completeness and much more. For a reliable representation of the route network and moving objects in real time. As a reliable source of information for the intelligent control of traffic flows. In the future, the digital map will form the basis of all decisions as a single source of truth.

The digital map and digital twin expert teams at NEXTRAIL have extensive process knowledge in defining, capturing, evaluating, locating, validating, transforming, visualising and distributing reliable infrastructure data. With many years of expertise from national and international lighthouse projects.

To make your data management even smarter, NEXTRAIL has developed an intelligent and reliable process with its TRAXIMIZER, TRAXPLORER and TRAXHUB product lines. For capturing, processing and providing secure infrastructure data for a digital and intelligent railway system of tomorrow.

    The advantages of digital maps and digital twins at a glance:
  • Core component for safe and high-performance operation of the digital rail system
  • Development of individual or standardised processes for efficient and reliable data generation and distribution
  • Minimises cost and project risks as early as the planning stage
  • Full security and availability of all infrastructure data
  • Creation of the data basis for BIM, digital maps, digital twins or single source of truth
