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..
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.
Strict safety requirements regulate the development of railway signalling and train control systems, covered by the CENELEC (European Committee for Electro-technical Standardization) EN 5012x rail standards
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.
Track circuits contributes for train detection but also for the vehicle’s speed control, since the electrical signals used for train detection can be exchanged between wayside and on-board for the transmission of speed commands.
Since the train can be considered the transport mode of the future, national railway companies and European Union are currently working for a continuos upgrade of sustainable rail transportation, in order to guarantee the best quality of life to European citizens.
Railway signalling can be defined as all systems used to control railway traffic safely, essentially to prevent trains from colliding. Over the years knoledgment and technology able to satisfy this issue have been implemented. ERTMS/ETCS is currently the most common signalling system adopted in Europe.
railwaysignalling.eu 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.
Why are you still continuing to send hundreds of CVs, even if it clearly doesn’t work! The questions are: why it doesn’t work? And how can I do to go further and overcome the obstacle of the first selection process? Maybe it’s time to change your CV and update it to the new ages!
The ETCS Limited Supervision mode has been recently defined as a fully standardized ETCS operation mode, to be interfaced with a national signalling system. It provides a flexible and scalable version of ETCS. It will be commissioned in Switzerland by Siemens within 2018, substituting the EuroZUB/EuroSignum National Signalling system.
Etihad Rail, the developer and operator of the UAE’s national railway network — signed a memorandum of understanding with Saudi Railway Company, or SAR, that will enhance collaboration and coordination for the rail industry among GCC members.
Bombardier Rail Jobcasting makes a lot of sense because where a job description communicates the opportunity, video and audio can help establish the sense of "fit" that is so important for a job seeker.
