TRIA has completed the works for the enhanment of the Bayobar depot at one end of the line, and also the turnouts on the main track. This works consist on replacing the existing track with the corresponding switch in 16 locations. Since it is done without interrupting the normal rail operation, the track works are done on working windows of 12 hours that go from Saturday night to Sunday morning. In each intervention, the existing track is removed, ballast cleared, the switch is installed, welded, leveled, aligned and right afther the works, the trains operate without speed restriction. For this works we are using some special equipment that allow to transport the switch completely assembled and welded from the assembly facility at the end of the line, and install it with sincronised positioners at the exact point on the track.
