Four more of the further functional modules 34 are arranged between the car body roof 40 and the inner ceiling 42. In particular, two of these four functional modules 34 are arranged under one of the coves 44 in each case. These two last-cited functional modules 34 are arranged obliquely relative to the horizontal.

    [0065] FIG. 3 shows a schematic section of the railroad car 2 along the sectional plane III-III from FIG. 1. In the section illustrated, one of the embarkation zones 26 of the railroad car 2 is depicted. FIG. 3 shows inter alia a section of the car body roof 40, the inner ceiling 42, the car body floor 46 and the floorpan 48. One of the previously mentioned entry doors 6 is also shown.

    [0066] Also depicted in FIG. 3 are a further three functional modules 34 of the control system 28. One of the further functional modules 34 is arranged between the car body roof 40 and the inner ceiling 42, in particular above the entry door 6, in the embarkation zone shown. The other two further functional modules 34 are arranged between the car body floor 46 and the floorpan 48 in the embarkation zone shown.

    [0067] These three further functional modules 34 are likewise communicatively connected via an electrical communication line in each case to the control elements 32 arranged in the switchgear cabinet 30, though these communication lines are not illustrated in this figure.

    [0068] FIG. 4 shows an exemplary embodiment of one of the previously mentioned functional modules 34 in a perspective view.

    [0069] The functional module 34 has a cuboid housing 50 made of metal. Two fastening elements 52 are attached to the housing 50, in particular to its top side as shown in the drawing. The fastening elements 52 are used to fasten the functional module 34 to another component of the railroad car 2. In the present exemplary embodiment, the fastening elements 52 are angle brackets which are screwed onto the housing. The fastening elements 52 each have two plate-like sections 54 which are so oriented as to be perpendicular relative to each other. In this way, one of said sections 54 is attached to the housing 50 in each case.

    [0070] The illustrated functional module 34 also has four externally accessible electrical interfaces 56, which are provided in each case for linking the functional module 34 via cables to one or more car-related elements. In the present exemplary embodiment, the interfaces 56 are designed as plug-type connectors. In addition, the interfaces 56 each have two threaded holes 58 by means of which a cable can be screwed onto the respective interface 56.

    [0071] The present functional module 34 also has two passive heat sinks 60 comprising a plurality of cooling fins 62 in each case, said heat sinks 60 being attached to opposite sides of the housing 50.

    [0072] The housing 50 is also equipped with a plurality of externally accessible blind rivet nuts 64. The blind rivet nuts 64 can be used to screw components such as e.g. the heat sinks 60 or the fastening elements 52 onto the housing 50. As an alternative or in addition to the blind rivet nuts 64, the housing 50 can have a plurality of threaded inserts.

    [0073] FIG. 5 shows a section through the housing 50 of the functional module 34 from FIG. 4. In addition to two of the previously mentioned interfaces 56 and a plurality of the previously mentioned blind rivet nuts 64, two printed circuit boards 66 and a printed circuit board support unit 68 are visible in FIG. 2, the printed circuit boards 66 and the printed circuit board support unit 68 being arranged in the housing 50. The printed circuit board support unit 68 is used to hold the two printed circuit boards 66 in place in the housing 50.

    [0074] A relay unit 70 which forms a control element of the control system 28 is soldered onto each of the two printed circuit boards 66. Furthermore, the two printed circuit boards 66 are electrically connected to the interfaces 56 of the functional module 34 by means of a back panel 72 which is arranged in the housing 50. For this purpose, the printed circuit boards 66 are plugged into slots of the back panel 72. In addition, the back panel 72 itself is electrically connected to the interfaces 56 of the functional module 34. In the present exemplary embodiment, by means of the back panel 72, each of the two printed circuit boards 66 is electrically connected respectively to two of the four electrical interfaces 56 of the functional module 34.

    [0075] The remainder of the previously mentioned functional modules 34 can be designed in an identical manner to the functional module described in connection with FIG. 4 and FIG. 5. Alternatively, some or all of the other functional modules 34 may differ from each other or from the functional module 34 described in connection with FIG. 4 and FIG. 5 in respect of their number of interfaces 56, type of interfaces 56, number of heat sinks 60 and/or number of fastening elements 52.

    [0076] Furthermore, the other functional modules 34 may differ from the functional module 34 described in connection with FIG. 4 and FIG. 5 in respect of those housing sides to which their fastening elements 52 and/or heat sinks 60 are attached.

    [0077] By way of example, FIG. 6 shows a section through a housing 50 of another functional module 34 of the control system 28. The following description is limited essentially to the differences of the present functional module 34 compared with the functional module 34 from FIG. 5, to which reference is made in respect of features that remain the same. Essentially identical or corresponding elements are designated by the same reference signs in each case, and features that are not mentioned are transferred without being described again.

    [0078] The functional module 34 illustrated in FIG. 6 has no back panel. Each of the electrical interfaces 56 of the functional module 34 is instead connected to a cable 74. The cables 74 have a plug-type connector 76 in each case. In addition, each of these cables 74 is connected with its plug-type connector 76 to one of the printed circuit boards 66 of the functional module 34, and therefore the printed circuit boards 66 of the functional module 34 are connected to the interfaces 56 by means of the cables 74.

    [0079] Furthermore, the electrical interfaces 56 of the functional module 34 from FIG. 6 have a different type of plug-type connector to the electrical interfaces 56 of the functional module 34 from FIG. 5.

    [0080] Although the invention is illustrated and described in detail with reference to the preferred exemplary embodiment, it is not limited by the example disclosed herein and other variations may be derived therefrom without departing from the scope of the invention.
