Abstract: A track receiver is located on-board a locomotive for receiving a first magnetic field produced in response to a cab signal carrier transmitted through a rail on which the locomotive is carried. The track receiver is oriented so that a second magnetic field produced during operation of a traction motor of the locomotive propagates substantially perpendicular to an axis of sensitivity of the track receiver, and is oriented so that the first magnetic field propagates parallel to the axis of sensitivity of the track receiver.
Abstract: A toy train system has movable and removable trigger devices to be located by a user wherever selected on the toy train track. The train locomotive includes the ability to activate a sound and a light signal which can correspond to the sound. The train locomotive is capable of manipulating and changing the speed of the train over the track. The track can have an ascending and descending tracks and curves, and the tracks have ridges for engaging the locomotive, and can be set up by a user as required.
Abstract: A method and apparatus for preventing energization or powering of an electric trainline until a test signal transmitted through the train is verified by the locomotive.

Abstract: A cab signaling apparatus for use on board a railway vehicle which is propelled on rail tracks by an electric drive motor. The invention utilizes a cab signal transmitted to the vehicle through a track circuit in the rails. On board receiving of the cab signal is done by a receiving coil, which may be mounted in front of the lead axle, as a current transformer around the lead axle, or at another location where the cab signal current is relatively strong. The cab signal that is sensed has a cab signal component and an interference component. On board the vehicle a sampled signal is taken which has the characteristic of the electromagnetic interference subjected to the cab signal receiver coil. The sampled signal is then subtracted from the sensed cab signal such that the sampled interference signal cancels the interference component of the cab signal.
