Abstract: The invention relates to an actuating device (1), in particular a drive (2), preferably for sequences of motion in the field of model building, with at least one magnetic field producing component (11, 32), in particular a coil (12, 33), for producing a magnetic field and an adjusting member (3) adjustable relative to a main body, which are adjustable relative to one another on electrically charging the coil (12, 33). The magnetic force for producing the relative movement is increased in the direction of the relative movement between the coil (12) and the adjusting member (3) and/or the main body (4).

Abstract: The invention relates to a coupling device (1,2) for model railways (3) where two model vehicles are connected and disconnected automatically with a closing element (12) and at least one coupling head (11); in the coupled state of the two coupling devices (1,2), the coupling head (11) of one coupling device (1,2) engaging the closing element (12) of the other coupling device (1,2) from behind and vice versa. In the coupling device (1,2) or in the vehicles (4,5) bearing the latter, especially model vehicles, an adjustment device (23) is arranged, with which the coupling head (11) and/or the closing element (12) of the coupling device (1,2) are adjustable relative to one another.

Abstract: A model vehicle such as a model railway vehicle includes a control and evaluation device located in the model vehicle, and a plurality of drive devices such as electric motors for moving the vehicle and for operating other movable components on the vehicle. A definable address is associated with the model vehicle, for example by being stored in a memory device connected to the control and evaluation device. The control and evaluation device includes or is connected to a switching network that is operable to selectably connect one of the drive devices to a regulating device in response to control signals from a central control unit. The regulating device is connected to a power supply and is operable to regulate the power supplied to the selected drive device in response to control signals from the central control unit. The control unit sends an address as part of its control signals, and the vehicle responds to the control signals if it has an address matching that sent by the control unit.
