To guarantee this, an intermediate phase of renovation of the installations has been designed that will allow the Plasencia-Badajoz section to be put into operation under the protection of the digital ASFA system at a maximum speed of 200 km\/h. This initial phase will result in a significant increase in safety, capacity and regularity of operation, since it will have double track along practically the entire route, eliminating telephone blocks and centralising control and management of the line at the Seville control centre.<\/p>\n
The signalling installations are based on interlockings, together with their intermediate blocks, which allow the safe movement of the trains through the application of SIL 4 systems. The solution designed for the railway network on the Plasencia-Badajoz section has electronic interlockings based on Alstom\u2019s Smartlock technology, with BAB and BLAU automatic block systems. In order to facilitate future maintenance, the interlockings are being upgraded. Some of the interlockings are electrical or even mechanical, as in the case of the Ca\u00f1averal or Aldea del Cano installations, which are still operated with a telephone block and will be replaced by a BAU type block. This equipment consists of six electronic interlockings located in Plasencia, Ca\u00f1averal RC, C\u00e1ceres, M\u00e9rida, Guadiana and Badajoz, supported by train detection systems installed in the field (Bombardier EBITRACK 400 coded audio frequency track circuits and Frauscher axle counters), Modular LED trackside signals from ICF, ASFA digital balises from Indra and Siemens MD2000 single-phase electric point machines to replace turnouts and derailers still equipped with manual switch stands, and Thales three-phase point machines for turnouts on the new platform.<\/p>\n
The overpasses and tunnel entrances are equipped with Logytel Falling Object Detectors (FODs), which trigger trackside signals in the event of an alarm<\/p><\/blockquote>\n
Unlike other lines, the energy system designed in this project includes a main supply from the electricity company at all locations, using the overhead line as a backup system. This solution, combined with the inclusion of medium voltage networks as an alternative supply in certain sections, makes it possible to minimise the number of emergency power generator sets to be installed. This all results in a more stable, efficient and clean power supply, reaffirming the railway\u2019s commitment to reducing greenhouse gas emissions.<\/p>\n
These unique features, together with the particularly rich and protected environment, add to the complexity of Ineco\u2019s work, which ranges from the drafting of the basic projects, environmental and expropriation documentation, inspection and testing of systems in the field, to the final supervision of the process of powering the installations, not to mention providing advice on the legalisation and contracting of the supplies.<\/p>\n

As a final complement, the deployment of the Bombardier ERTMS Level 2 system is planned for the installations of the new line between Plasencia, C\u00e1ceres and San Nicol\u00e1s split, as well as on the line between M\u00e9rida and Badajoz. This train protection system is managed through two RBCs located in C\u00e1ceres and Badajoz, which are in constant communication with the electronic interlockings supported by the GSM-R mobile communications network, and grant movement authorisations to the trains on the lines that they protect.<\/p>\n
The Santa Justa control centre in Seville will provide support for the centralised control and efficient operation of these installations. The Thales CTC will unify the remote control of the interlockings of lines L026 (Plasencia-C\u00e1ceres-San Nicol\u00e1s split), L500 (Monfrag\u00fce-Casar de C\u00e1ceres triangle) and L520 (Villanueva de la Serena-Badajoz), which was previously distributed between the Chamart\u00edn and Manzanares CTCs. A new Bombardier ERTMS central control station will be responsible for controlling this train protection system, and a new Indra remote control for auxiliary detection systems will provide operators with all the necessary information regarding the falling-object detectors.<\/p>\n
