High speed faces a new phase in Spain after Scar Pointe announced its line Madrid-Barcelona will operate at a speed of 350 kilometers per hour, which will reduce the journey to less than two hours of travel.. This is it leader … Which will see less times But the idea is that it extends across the Spanish railway network. To achieve this speed, it is essential that the design allows for the placement of floating beams, which seek to isolate vibrations.
The choice of this corridor as the opening line for this high speed, according to Puente, is due to the width of the road between the capital and Barcelona allowing “traveling at a speed of 350 kilometers per hour without touching it.” However, Abraham Carrascosa, former dean of the Official College of Civil, Canal and Port Engineers of Andalusia, explained to ABC that The offer is the same on all high-speed roads in SpainJust as it will be installed in the Madrid-Barcelona corridor, it can be implemented in Seville.
Sleepers, as defined in a report from the Spanish Railway Foundation, are the support element to which the rails are fixed and can be made of wood, concrete or metal. These new supports, which the Minister referred to as “Erosros” or “floating sleeper”, are an innovative, geometrically shaped design that prevents trains passing at very high speed from lifting ballast stones in their path, thus avoiding damage to the underside of trains and improving vehicle maintenance and safety. The Adif contract specifies that these are new items PR-VE strapsfrom a single piece of prestressed concrete of mixed width, including the fasteners to be installed. As was specified last Monday during the announcement of the AV350 project, the line will be renewed after the completion of the line linking Atocha and Santa Justa, which is undergoing the renewal of more than 70,000 girders for the installation of those girders. Type AI-VEsimilar but not exactly the same.
Verified in 2020
The functionality of the overhead track was verified on a section of the Madrid-Barcelona high-speed line, specifically at PK69+500, in December 2020. But when announcing in 2021 the replacement on the Seville line with this type of installation, the desire to operate this line at a speed of 350 kilometers per hour was not specified. “the The Madrid-Barcelona and Madrid-Seville lines were implemented to the same technical standards “Just as the work will be done in this department, it can be done in Seville,” says the former dean.
From the central government, it has not been clarified how or whether the implementation of the AV350 project in the province of Seville will be a reality. Minister Puente’s announcements only specify that the Seville-Barcelona line will see its time reduced due to… Construction of a new station in Parlawhich will prevent trains from Andalusia from entering the Atocha or Chamartín stations in Madrid. Carrascosa describes this announcement as an “election campaign”: “We will have to see if this 350-kilometre train will reach Barcelona,” he declared.
