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.
Sustainability is the key word of this train with the Bombardier's ECO4 technologies. Today the ECO4 portfolio includes 15 energy-saving solutions that serve as the backbone of modern fleet management and rail technology.
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.
