The lines involved will link Valladolid, with Venta de Ba\u00f1os and Leon, and Venta de Ba\u00f1os with Burgos. Completion of these projects will accelerate high-speed services between Madrid, Gijon, Bilbao and San Sebasti\u00e1n.\r\nBombardier, whose share of the contract is worth \u20ac144m, will install its Interflo 450 Level 2 system on the Venta de Ba\u00f1os - Burgos section. The system will comprise an Ebi Com radio block centre, Ebi Link balises, Ebi Lock 950 computer-based interlocking, and train detection systems.\r\nBombardier will work with Nokia Networks to deliver GSM-R solution for the projects. Nokia will supply its Flexi Base Stations, fibre optic repeaters, and Transcoder\/Sub-Multiplexer (TCSM) along with its NetAct network management system. The company is also providing network operations, network design, project execution, network implementation, and maintenance services.\r\nBombardier will install its system within 24 months, and will provide a two-year warranty plus maintenance for 20 years.\r\nIn addition, Adif has selected Nokia directly to deliver GSM-R on the 50km La Robla - Pola de Lena high-speed line, which will eventually form part of the Le\u00f3n - Asturias high-speed line, with delivery set for March 2015. Adif awarded Siemens Rail Automation and Thales a \u20ac54m contract to equip the line with Asfa ATP system, ERTMS and associated signalling and telecommunications equipment in April.
