A method and an apparatus that improves the motion and sounds of a model locomotive such that they more closely represent or simulate that of a real locomotive. The motion and sounds are changed in such a way that it is more realistic when compared to a real locomotive that is pulling a heavy load.

A gear assembly for a toy vehicle is disclosed. The gear assembly may be selectively placed in a drive position in which a first set of wheels and a second set of wheels are connected to the motor through a first gear train and a second gear train, respectively. The gear assembly may be selectively placed in a freewheel position in which the first set and second set of wheels are disconnected from the motor. The gear assembly is switched from the drive position to the freewheel position using a lever that pivots to move a gear in the first gear train to disconnect the gear and break the first gear train when a gear is moved in the second gear train to disconnect the gear and break the second gear train. Through the lever, the first and second gear trains are positioned in concert.

A model train control system providing a more realistic modeling of the movement, sound, smoke, and lighting effects of a model train is disclosed. A number of dynamic inputs are used to control such effects. Novel features include providing a dynamic variable speed compensator, a dynamic engine load calculator, automatic dynamic momentum, an adjustable train brake, spectrum control, a velocity controller, pressure sensitive effects, a voice activated dispatcher system, a train location and information reporter network, two digit addressing, a traffic control system, accessory control, a model train Central Control Module, and removable memory modules.

A decoder for model train locomotives or rolling stock including: a data input; a sensor, separate from the data input and arranged to receive a first energy signal and transmit a first trigger signal; a memory element configured to store a first address identifying the decoder; and a processor configured to receive first data including a group identity address, receive the first trigger signal; and store the group identity address in the memory element. The sensor is arranged to: receive a second energy signal; and transmit, in response to receiving the second energy signal, a second trigger signal. The processor is configured to: receive the second trigger signal; receive second data including the first address and first operating instructions, associated with the first address, for a device for a model train locomotive or rolling stock; and transmit the first operating instructions. The group identity address identifies a group of decoders.

Provided is a train set structure including a locomotive and a plurality of cars and track segments. The track segments can be connected and separated. The locomotive includes a driving unit, sprayer, liquid input hole, switch, and luminous body. The driving unit has driving rollers abutting against the track segments to drive the locomotive. The sprayer contains a liquid, with a vibrator disposed at the bottom of the sprayer, adapted to vibrate the liquid to produce aerosols, and electrically connected to a control circuit and a battery module for supply power to the vibrator. The switch is electrically connected to a music generator. The cars are connected and separated by connection hooks engaged with and disengaged from connection hole components respectively. The locomotive and cars move on the track segments automatically, accompanied by aerosols emitted from the sprayer, musical sounds, and flashes to achieve liveliness and entertainment.
