Type of vehicle:
Self-propelled electric train unit, with Line at 25 kV-50 Hz, of 250 km/h.
Unit made up of 6 cars TCB-MIFc-MIF-MIF-MIF-TCF, which can be extended up to 8 cars by adding an additional 2 intermediate MIF cars.
The Unit can be coupled to another to make up a twelve car train.
Two electric motors per motor car, located in the carbody and controlled by IGBT, which operates one of the axles of each bogie via a cardan joint. A regenerative electric brake is also supplied, which is complemented with pneumatically operated disc brakes with a wheel slide protection system.
One traction inverter per car which operates on the two carbody motors. There are four auxiliary converters per train and three of these are in operation with the third only coming into operation should one of the other two fail.
Modern and functional interior distribution, with eight WCs per unit: 7 standard WCS in the TCB, MIF and TCB cars and a WC adapted for PMRs in the MIFc car. Access doors in the centre of the cars with two semi-saloons to the left and right of the central vestibules.
Bogies:
Axles for a track gauge of 1435 mm, a motor axle and trailer axle per bogie.
Monobloc non-alloyed steel wheels, with low carbon content and with tempered flange surface.
Primary suspension by means of coil springs and secondary, pneumatic suspension.
Welded steel frame.
The carbody is supported on a load bolster which is rigidly connected, under which the secondary suspension is mounted. The horizontal forces are transmitted via a drag pivot pin.
The service and emergency brake consist of steel discs produced in sections and screwed to the axle. The parking brake consists of accumulator springs located in one cylinder per axle.
