Modification of track circuits for the Carranza-Aranguren section

Due to the electrification of section Carranza-Aranguren the track circuits were modified as these were conventional track circuits adapted to a non-electrified track.

This modification consists of:

• Removing of cables of 1x4mm section, including its collection in coils and its relocation.
• Supply and overhead wires in existing chanelling of 4x1.5 mm.
• Insulated gasket of 54 kg. (1 wire) of 9 m long, including all materials. Fully assembled.
• Supply and installation of inductive gasket.
• Reform of cabinets of track circuits for adaptation to the new situation, including materials, engineering, testing and commissioning.
• Reform cabinets for track circuits for adaptation to the new situation, including materials, engineering, testing and commissioning.
