How to maximize throughput on existing infrastructure
Digitalization and rail automation can help maximize throughput for mainline and mass transit, saving considerable costs and energy.
Operators of local, national, and international networks all face the same challenge: how to quickly grow passenger and freight volumes using existing infrastructure. Maximizing capacity and further increasing punctuality on existing lines not only saves money, it also uses fewer resources and reduces energy consumption – so the environment benefits as well. Digitalization is one of the best ways to achieve this, primarily by taking advantage of the latest developments in ATO and CBTC, while simultaneously ensuring highest levels of passenger safety.
The beauty of these software-driven technologies is how they create significant real-world benefits with software-driven solutions. Today, we are already achieving this for customers around the world with mainline and mass transit solutions.
Optimizing mainline capacities with more intelligent trains
Mainline infrastructure is typically shared by different rail operators, so the implementation of new technologies requires careful orchestration. In Europe, ETCS (European Train Control System) is the basis by which ATO (Automatic Train Operation) can be efficiently implemented. We have delivered pioneering ATO over ETCS solutions for numerous clients, including a recent project for Deutsche Bahn in the Hamburg regional network (S-Bahn).
Improved throughput for S-Bahn Hamburg
Simply laying new tracks was not an option for the densely populated and highly developed region of Hamburg. The challenge was to increase capacity on existing lines, while also ensuring timetable stability, improving punctuality, and shortening stopping times.
The challenge is to provide more capacity on existing infrastructure without having to build new tracks.”Jan Schröder, project manager, Deutsche Bahn
ATO over ETCS boosts capacity and efficiency
We implemented an ATO over ETCS solution combining a high degree of automation (GoA2) with the latest European harmonized train protection system (ETCS). Besides improving throughput, the solution also helps reduce energy consumption by up to 30%, by optimizing the speed profile and acceleration behavior of the trains, for instance. Operation costs are also lower thanks to a reduction of wear and tear on mechanical parts.
In the words of Jan Schröder, Deutsche Bahn’s project lead, “The solution allows us to run trains at closer intervals, to simply have more trains on the tracks and in this way better serve the passengers.”
Improving the livability of cities with more efficient mass transit
Most urban rail networks have the advantage of operating in closed systems, making the implementation of customized automation solutions possible. We deliver this with our enhanced CBTC (Communications-Based Train Control) as part of our Trainguard MT solution. Already operational in mass transit networks around the world, a recent project in Oslo foreshadows the future of maximizing capacity through the cloud.
We have done a very important contract with Siemens for the metro System in Oslo. And now, Siemens will be the most important supplier for Sporveien.Cato Hellesjø, CEO Sporveien AS
Innovative train control for Oslo metro
Operated by Sporveien AS, the metro in Oslo is over 50 years old and needed to modernize its 94 km network. Siemens Mobility was chosen thanks to our comprehensive offer at a competitive price. A core component is Trainguard MT, a solution capable of meeting Oslo’s flexibility requirements thanks to constant enhancements. As a particular highlight, the CBTC radio channel will utilize 4G communication.
CBTC to boost overall efficiency
Cato Hellesjø, CEO of Sporveien, sees immense potential: “With the CBTC technology, we are revolutionizing the underground network with a modern, innovative system that enables greater automation of the trains, a higher capacity, and improved throughput.”
The prospect of CBTC in the cloud powered by 5G promises many other advantages in the future, such as up to 90 percent less network cables and up to 25 percent less lifecycle costs. With CBTC energy consumption can be reduced by up to 20 percent, reducing the carbon footprint.
Infrastructure in the cloud
Even greater efficiency and performance are possible when control and safety technology are moved from proprietary hardware to cloud-based, highly flexible systems. Whether for mass transit or mainline, our DS3 platform is the key building block to achieve this.
