In addition to ETCS, ATO GoA 2 and further technologies,
FRMCS is also being installed as part of the ongoing retrofit
of 333 multiple units for the Stuttgart Digital Node (DKS).
130 new regional multiple units will also receive FRMCS “ex
works”. In the meantime, a large part of the hardware has been installed in the first first-of-class trains.

Article in "Signal & Draht" | Experience gained from track field networking at the Stuttgart Digital Node (part 1) | 04/23

The first design of a digital interlocking at a large German
railway node has brought a number of experiences
to light. The present cabling concept is currently reaching its
limits, particularly in existing train station areas that are to be
temporarily equipped not only with European Train Control
System (ETCS), but also with Class B under the high redundancy
requirements. A number of optimisations have been developed
based on this experience.

A Comprehensive Framework for Evaluating Vision-Based On-Board Rail Track Detection | 03/23

Reliable and precise rail track detection, and its verification, are crucial parts for many on-board environmental perception functions of automated trains. By using an exemplary Neural Network, this scientific paper shows how precise track centerline detection can be realized and how the precision can be evaluated with a novel metric, presented for the first time in this paper. Scientific paper on AI based rail track detection as accepted and presented at the 2023 IEEE Intelligent Vehicles Symposium (IV) of the IEEE Intelligent Transportation Systems Society (ITSS).

Article in "Signal & Draht" | Innovative antenna systems for FRMCS -field trials at 1.9 GHz | 11/22

The Future Railway Mobile Communication System
(FRMCS) will be the successor to GSM-R. It will be
based on 5G technologies and will enhance mobile train-to-ground communications in rail operations. Improved radio
access and core network architectures as well as innovative
antenna systems in FRMCS will enable higher transmission
rates, lower latencies and high reliability for any future data
transfers within the scope of the digitalisation and automation
of railway services. This article focuses on multi-antenna
radio technologies and their benefits for FRMCS networks
at 1.9 GHz

Article in "Signal & Draht" | Innovative cooperation for the vehicle equipment at Stuttgart Digital Node | 09/22

Within the sector initiative Digitale Schiene Deutschland Alstom, Deutsche Bahn AG (DB) and the state of Baden-Württemberg are jointly breaking new ground for the retrofitting of 333 regional and commuter trains for the Stuttgart Digital Node (DKS). Four key topics for the digital rail operation of the future were jointly worked as part of an Innovation Cooperation and brought to implementation maturity. The resulting solutions are intended to serve as models for upcoming retrofit projects.

Research Report | SIL4 CLOUD | 09/22

Deutsche Bahn along with industry and academic partners are jointly investigating a key element of future rail operations – the SIL4 Cloud. The collaboration has been undertaken in order to gain synergies from different points of view, experiences, and expertise, such as in the specification of major high-level requirements for a SIL4 Cloud.
Article in "Signal + Draht" |5G for the digital rail system of the future – the prospects for FRMCS |03/22

The digitalisation of the rail system makes real-time data transmission between train and trackside through a highperformance wireless connection increasingly important. The connectivity required for this is being realised with the introduction of the 5G-based Future Railway Mobile Communication System (FRMCS). This article provides a summary of the future use cases, the FRMCS architecture and the comprehensive activities undertaken by DB within the context of FRMCS standardisation, development and field trials.

Article in "Signal + Draht" | SIL4 Data Center | 10/21

With digitalization, a multitude of new technologies will be introduced to the railway system. These will not only place high demands on performance and connectivity of IT environments, but also strict requirements on safety. Digitale Schiene Deutschland and Siemens Mobility GmbH have developed the basic architecture for "SIL 4 Data Centers".

Article in "Signal & Draht" | Optimising block division with ETCS Level 2 in the Stuttgart Digital Node | 7-8/21

The block division in the Digitaler Knoten Stuttgart has been optimised using new methods as part of a pilot scheme included in the “starter package“ of the Digitale Schiene Deutschland project. The goal is to minimise the headways across all train pairs, thus maximising the track capacity. While ETCS without Class B systems makes signalling planning much more flexible.
Report in ZIB "Zuse Institute Berlin" | Microscopic Timetable Optimization for a Moving Block System | 06/21

We present an optimization model which is capable of routing and ordering trains on a microscopic level under a moving block regime. Based on a general timetabling definition (GTTP) that allows the plug in of arbitrarily detailed methods to compute running and headway times, we describe a layered graph approach using velocity expansion, and develop a mixed integer linear programming formulation.
