Abstract: A system and method is provided for powering and/or controlling a plurality of model devices, including at least one model vehicle. In one embodiment of the present invention, the system includes an adjustable transformer in communication with at least a model train. The adjustable transformer is configured to convert an AC voltage into first and second AC output voltages based, respectively, on positions of first and second input devices. The adjustable transformer includes a processor configured to receive input signals from the input devices, and to generate corresponding control signals, which are used by drive circuits to convert an AC voltage into first and second outputs. The processor is further configured to display data concerning the first output on a display, and to replace the data concerning the first output with data concerning the second output if a signal is received from a sensor, indicating that the user has interacted with the second input device.

The apparatus includes an EOT device engageable with a model railway vehicle that can be easily installed and removed for relocation between model railway vehicles. A control system for such EOT device. At least a portion of an electronic circuit is disposed at least one of on a truck of such model railway vehicle and a body portion of the EOT device for power conversion and light signal timing and at least one light element is disposed at least one of in and on such EOT device and connected to receive a signal from the electronic circuit.

Abstract: A truck for use on a piece of model railroad rolling stock, the truck having axle/wheels sets associated therewith includes two identical truck portions, which, when joined, form a model railroad truck frame, which is held together by mechanical impedance by a frame retainer located in a central mounting structure formed by joining the two truck portions.

Abstract: A method for speed control for a motor of a locomotive of a model electric train is presented. A method in accordance with the present invention includes sensing an operating velocity of the motor and the operating current provided to the motor, and then producing a signal corresponding to the operating velocity and a signal corresponding to the operating current. A method in accordance with the present invention further includes providing the operating velocity signal and operating current signal to a controller and establishing a target motor velocity. A method in accordance with the present invention still further includes calculating a target current configured so that the motor reaches the target motor velocity, and then changing the operating current to the target motor current to achieve the target motor velocity.

Abstract: A spring metal wiping contact that bears on the upper tread of a model railroad locomotive wheel to provide enhanced electrical conduction and equalized suspension under all positions of wheel movement, and ease of cleaning this contact without having to dis-assemble the locomotive during regular and normal wheel cleaning maintenance.

Abstract: A non-electric rail-cleaning device for toy and model trains is described including providing wheels and a truck as an efficient means of keeping rails clean of foreign material. The design provides a convenient and economical means of eliminating the manual operation of cleaning track to ensure good electrical contact between the current-carrying rails and locomotive.

Abstract: A model train locomotive has a set of drive wheels and a power system for rotating the drive wheels. The power system comprises an electric motor mounted for rotating a power input shaft, a control mechanism for regulating the amount of electric current supply to the motor for varying the rotational speed of the power input shaft, and power transmission assembly for transmitting power from the power input shaft to rotate a driven output shaft which is coupled to rotate the locomotive drive wheels. The power transmission assembly includes a flywheel and gear train for rotating the flywheel about an axis of rotation when the electric motor is rotating the power input shaft while the driven output shaft is not rotating.

Abstract: The present invention provides a drive assembly for a model toy train which connects a single drive shaft from an electric motor to a pair of discrete truck assemblies. The drive shaft drives a plurality of pinions which in turn drive a pair of worm shafts which extend toward the truck assemblies. A pair of worm wheel shafts are driven by the worm shafts to drive the wheels on the truck assemblies. A saddle and bearing combination rotationally connects the model toy train to the truck assemblies allowing the truck assemblies to freely rotate.
