Sèrie 3000/4000

The 4000 series were jointly conceived in 1984, and entered service between 1987 and 1990, with the aim of renewing the existing material in L1 and the 4000 series are Iberian wide and are intended for the L1. Currently, the Serie 4000 operates on line 1 and the Serie 3000 operates on line 3 of the Barcelona metro (Barcelona, Catalonia, Spain). The difference between them is the track gauge: 4000 is designed for Iberian (1674 mm) and 3000 for the International (1435 mm).

They had a very innovative design for the time, with an image of modernity. It was designed by Miquel Milà. It was immediately given the nickname “Japanese”: for this design with straight shapes and its Mitsubishi engine.

Initially, the power outlet was made using upper contact pads (series 4000), since the electrification of line 1 was through the third rail until 2002. From the beginning they were also equipped with pantographs, since the coach houses they were electrified with catenary. Since 2002, pantographs have been used to travel along the line. These series were the first to incorporate ATO (automatic driving, although assisted by the rider), air conditioning, public address system with automatic announcements, line plans with LED technology, indicators on the side of opening the doors and manual opening of the doors using a handle.

*Not to confuse with 3000 series from Madrid.

The convoys were built by CAF, MTM and MACOSA. The 24 convoys of the 4000 series did it on L1 between 1987 and 1990. On Line 1, compositions of 5 cars circulate, arranged in the following way: MA-MB-MA-R-MB.

Between 2007 and 2013, the convoys of both series were renewed. The most significant changes were the addition of interconnecting rings between cars, the change to laterally arranged seats, the modification of the vertical bars and the installation of video surveillance cameras. Externally, the fronts and top of the sides were painted in TMB corporate red, the turn number indicators were replaced with LED panels and the headlights were changed.

It is a monocoque type bodywork, of great lightness built entirely in steel weakly alloyed with copper in order to improve its resistance to corrosion. It consists of four lateral access doors, each with two sliding-sliding-type leaves. A service compartment in the rear of the service serves as a means of communication with the attached car, as well as the front front door, as well as the two doors of the driver’s cabin.

All the passenger doors, as well as the two cabin doors, are connected to a door check loop, which prevents the train from starting or continuing its march if there is an open door (made visible by turning on the white pilot from the side of the box of each affected car).

The large windows have shatterproof glass windows and are completely closed, with the exception of the two located at the back of each car, which can be operated by means of the corresponding washer. The roof, trocopyramidal in shape, has maintenance walkways as well as the corresponding resistance blocks, as well as the evaporative air conditioning equipment and the pantographs (in the motor cars).

The fronts have four headlights (two with white light and two with red light), On the sides of the boxes, located at the left or right ends, we find three pilot lights: one amber (trigger activated), one white (existence of one or more open doors), and one blue (ATP-ATO system disconnected).

The covering of profiles, separators, headers, partitions and cabin partitions is based on elements of Polyester reinforced with glass fiber (FRP), with a fire resistance rating of M2.

The ceiling is based on aluminum profiles, with openings where the air conditioners are located, for the best diffusion of them. This manages to hide in a simple and effective way the ducts of the roof of the car.

The floor is based on a fireproof plywood board covered with synthetic tiles (also qualified as M2), sealed together. The lighting is achieved by means of a row of fluorescents, two by side, located in the upper part of the ceiling, of 65W each. Below each one of those placed in those facing the doors (two on each side), a line thermometer based on LEDs that indicate the next station, as well as the current route, has been placed.

Inside, we also find alarm triggers, located on the side of each door frame, with an intercom to contact the operator and indicate the reason for the trigger.

The door system used is of the sliding-sliding type, double and combined, with electric drives, with independent electronic regulation per door. They are designed and supplied by Faiveley. The door is opened by turning the handle at the end of the door towards the inside of the door. They have a loop that prevents the train from continuing in the event of an open door.
