79 POSTS0 COMMENTS is a technical e-journal and web community. It was born and grows with the purpose to share high-tech knowledge about the most advanced and widespread signalling and train control European solutions. Young and experienced rail-signal engineers are welcome to participate to the group’s web community, by publishing their own technical articles about the main topics of railway signalling and train control European solution.

Corrective, Preventive and Predictive maintenance for railway applications

Railway maintenance is defined as the process of preserving a working condition of a railway equipment, along the track or related to rolling stocks, but there are actually different approach to mantain a railway asset or service..

Introduction to CBTC system description

With CBTC, moving blocks introduce to the concept of contiguous track, because the railway is represented as a single contiguous block, rather than a set of adjacent blocks. This means that the safe separation behind the preceding train is dynamically calculated based on the maximum operating speeds, braking curves and locations of the trains on the alignment. Also, in this way the capacity of the railway is extremely increased.

Conventional vs CABS vs CBTC railway signalling & their impact to capacity

In railway signalling, capacity can be defined as the maximum number of trains that can pass a given location during a given time period at a specified level of reliability.

How to write a Risk Management Plan: a system-based approach

How to write Risk Management Plan? First, identify and categorise the risks (probability of occurrence and Severity). Then, define the actions to be performed to reduce your risks. Eventually, make sure you really do what the register addresses, rather than doing it just to make your manager happy!

ERTMS in the UK: a video by Network Rail

In this video, Network Rail shows the power of the ERTMS in the UK and highlights the benefits that will come over after its implementation.

Modeling and simulation of safety critical systems

Simulation is used before an existing system is altered or a new system built, to reduce the chances of failure to meet specifications, to eliminate unforeseen bottlenecks, to prevent under or over-utilization of resources, and to optimize system performance.

Thales to install CBTC into London Underground Network, as part of the 4LM (4 Lines Modernisation) programme

After awarding a 1billion euro contract, Thales will deliver an Automatic Train Control (ATC) system for four of London Underground’s lines: District, Circle, Metropolitan and Hammersmith & City.

Requirements Management for safety critical systems: a new white paper in PDF format!

This paper will drive you across the different phases of the V-cycle for railway application, by explaining the key role of requirements during each phase and presenting the Systems Engineering activities required to support and control product development.

ALSTOM acquires Signalling Solution. What are the consequences for the UK railway market?

With this acquisition, ALSTOM improves its power in the UK railway market, by standing as one of the strongest competitors as part of Network Rail’s major signalling framework agreement.
