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.
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.
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.
That's the end of the Italian Excellence for railway signalling applications. Which will be the consequences for the market? What do the current (and potential future) Ansaldo employees need to expect? How stronger will Hitachi become? All of this will come soon.
Trenitalia confirmed its Frecciarossa 1000 would begin running on June 14th of this year with it will be possible to go from Rome to Milan in just 2 hours and 20 minutes.
Hitachi has reached a binding agreement with the board of Finmeccanica to acquire all of the shares in AnsaldoBreda and the Finmeccanica's 40% stake in Ansaldo STS.
Insigma offer for AnsaldoBreda and Ansaldo STS is worth more than 1.5 billion Euros and a relevant investment plan; Hitachi might have been discouraged by unprofitable contracts
With flexible interfaces to Traffic Management, ERTMS L1/ L2/L3, Zone Controller and other Interlockings, Ansaldo STS MacroLok seems to be the natural evolution of the previous STS Interlockings currently in service around the world
Finmeccanica. Today, the Management Board unless last-minute surprises, should appoint Sergio De Luca as general manager of Finmeccanica.
In 1975 he began his collaboration with the...
Ansaldo Breda, the Italian Finmeccanica Company of the railway industry, following the country-trend, is in debt for 10 years. The company in the first half of the year has doubled its operating loss to € 68 million, while revenues fell by 26% to € 264 million.
