[0021] Figure 1 A railway motor car 10 or railway locomotive according to one embodiment of the application is shown. The motor car 10 is intended to be coupled to a rail vehicle of the passenger car type to form a train. The motor car 10 is preferably a motor car of a very high speed train or a locomotive to pull passenger cars or freight cars.

[0022] The power car 10 comprises a body 12 and at least two bogies (not shown) and at least one traction motor 14 arranged under the body 12. The traction motor 14 is intended to move the wheels of the bogies. The power car 10 also comprises a plurality of technical cabinets 15.

[0023] The body 12 comprises a roof 16 and a floor 18 which delimit it in the vertical direction. The bogies and the traction motor 14 are arranged under the floor 18. The body 12 also comprises side walls 20.

[0024] The body 12 has an elongated shape. By way of example, an orthonormal basis (X, Y, Z) is considered, in which the direction Z represents the vertical direction. The body 12 mainly extends in the direction X, which corresponds to the conventional direction of travel of the power car 10.

[0025] The body 12 comprises Figure 1 a technical compartment 22 shown in cross section.

[0026] The technical compartment 22 notably comprises: - first means 24 for detachable connection, and - a cable tray 26.

[0027] The first means 24 are intended to be detachably connected with the technical cabinets 15. The first means 24 comprise two rails 28 which are fastened to the floor 18 and extend in the direction X. The two rails 28, which are substantially identical, will be described in more detail below.

[0028] The space located between the two rails 28 in the direction Y delimits a central corridor 30 in the technical compartment 22. Advantageously, the central corridor 30 has a width in the direction Y which is between 500 mm and 750 mm, preferably equal to about 750 mm. This width is determined so as to allow an operator to pass comfortably without substantially limiting the available volume of equipment of the power car 10.

[0029] The cable tray 26 extends in the direction X and is fastened to the floor 18 in the central corridor 30 between the two rails 28. The cable tray 26 will be described in more detail below.

[0030] The technical cabinets 15 are mounted in the technical compartment 22, on either side of the central corridor 30, close to the side walls 20.

[0031] Each technical cabinet 15 comprises a box 32 and second means 34 for detachable connection with the body 12. The box 32 has a substantially rectangular shape and is intended to house electrical and / or electronic equipment of the power car 10. In a variant, the box 32 is intended to house pneumatic equipment, for example hoses.

[0032] Figure 2 A detailed view of the rail 28 and of the second means 34 for detachable connection of the technical cabinet 15, assembled together with each other, is shown.

[0033] In Figure 3 The rail 28, also visible in the perspective view, has a substantially constant cross section along the direction X.

[0034] More particularly, in the illustrated embodiment, the rail 28 comprises a lower element 40 and an upper element 42. The lower element 40 and the upper element 42 each have a constant cross section, so that they can be made via bending and / or extrusion of a single piece along the direction X. The lower element 40 and the upper element 42 are made, for example, of steel and / or stainless steel.

[0035] The lower element 40, intended to rest against the floor 18, has a U-shaped cross section, the branches 43 of which are upwardly directed.

[0036] The upper element 42, intended to rest against the ends of the branches of the U, is configured to be detachably connected with the second connection means 34. In the illustrated embodiment, the upper element 42 comprises a substantially horizontal upper wall 44, in which a longitudinal slot 46 is formed. Preferably, at least one first end 48 of the slot in the direction X is an open end.

[0037] In the illustrated embodiment, the upper element 42 comprises a substantially tubular recess 50, on which the longitudinal slot 46 opens. The upper element also comprises two substantially flat wings 52, provided on either side of the recess 50, each of which rests against one branch 43 of the U of the lower element 40.

[0038] The lower element 40 is formed, for example, by bending a sheet of metal, and the upper element 42 is formed by extrusion, the two elements then being welded to one another.

[0039] The second connection means 34 of the technical cabinet 15 comprise at least one foot 56, which extends substantially vertically below the box 32. Preferably, the second connection means 34 comprise at least two substantially identical feet 56 aligned along a first edge 58 of the box 32. The first edge 58 is oriented along the direction X and is adjacent to the central corridor 30.

[0040] The foot 56 comprises a bottom end in the form of a substantially horizontal plate 60, which can rest against the upper wall 44 of the upper element 42 of the rail 28. The plate 60 is equipped with a mechanism 62 fastened to the upper wall 44.

[0041] In the illustrated embodiment, the fastening mechanism 62 is a detachable fastening device of the screw type, comprising a fastening rod 64, which passes through the longitudinal slot 46 and the plate 60 of the foot 56, and a nut 66 connected to the fastening rod 64 above the plate 60.

[0042] In the loosened configuration of the nut 66, the fastening means 62 can slide in the longitudinal slot 46 in the direction X. In the tightened configuration of the nut, the fastening means 62 tighten the foot 56 in the direction X on a specific position of the rail 28.

[0043] The box 32 comprises a second edge 68, opposite the first edge 58 and adjacent to the side wall 20 of the body 12. In the illustrated embodiment, the second edge 68 of the box 32 rests against a horizontal shoulder 70 extending in the direction X along the side wall. According to a variant not shown, the first connection means 24 comprise third and fourth rails 28 instead of the shoulder 70, and the second connection means 34 comprise additional feet 56 on the second edge 68 of the box 32 for making a connection similar to the one described above.

[0044] The cable tray 26 comprises a channel 72 and upper plates 74. The channel 72, which extends in the direction X and is arranged on the floor 18, is intended to house the equipment cables and / or passages (not shown) of the motor vehicle 10.

[0045] The channel 72 comprises in particular a floor 76 and substantially vertical uprights 78. Preferably, the channel 72 has a substantially constant cross section, so that it can be manufactured by a single piece by a bending step. According to one embodiment, the floor 76 and the uprights 78 have perforations (not shown) regularly arranged in the direction X and enabling the connection with other elements.

[0046] The upper plates 74 are arranged along the channel 72. Preferably, the upper plates 74 are distributed at regular intervals along the channel, so as to form a support enabling the operator to pass through the central corridor 30 above the cables and / or passages housed in the channel 72.

[0047] The upper plates 74 are fastened to the uprights 78 of the channel by removable fasteners 80 of the screw or rivet type, in particular cooperating with the perforations formed in the uprights.

[0048] The detachably connected means 24, 34 as described above constitute a standardised system for equipping technical carriages of motor vehicles or locomotives. This is because the rails 28 associated with the feet 56 can position the cabinet 15 in an infinite number of positions in the direction X. Therefore, the same rails 28 can equip different motor vehicles 10, independently of the position of the cabinet 15 chosen in the technical carriage 22.

[0049] Likewise, the feet 56 can be associated with boxes 32 of different sizes. Finally, the same rail profile 28 is used along both sides of the central corridor 30, which can make the first connection means 24 simpler to form.

[0050] Also, the cable tray 26 used in association with the rail 28 has a standard profile that is easily adapted to different technical carriages 22.

[0051] The production costs can be reduced with respect to the laser cutting of the metal plate, by the extrusion and bending of the rail 28 and by the bending of the groove 72, which are required to produce the slat-like floor beams of the prior art.
