A computerized system and method of managing subway trains along a two-track subway line to allow express travel in combination with local service. Express trains catch up to local trains at express stations along the line, and provision is made to allow the express trains to physically or “virtually” pass the local train at those stations. Embodiments in which the express trains physically pass the local train include direct train-to-train transfer facilitated by side-by-side tracks at the express station occupying reduced footprint. In other embodiments, virtual passing is accomplished by changing the type of service provided by trains at express intervals: a local train “transforms” into an express train and vice versa. Embodiments enable passengers to transfer between trains at express stations so that these “relay” passengers can travel faster than any specific train.

Apparatus for providing effective amounts of high-frequency AC power to a long primary trackway (1102), used for inductive power transfer includes transconductance-pi filters (1105) for deliberate mismatching; resulting in independence of current flow and track impedance. These cause the source (1101) to appear as a voltage source and the trackway to appear as a low reactance. Shorting the output (1106) cuts the connected trackway from power without harm. The filter can cause a voltage step-up so driving a longer track. Track termination apparatus is disclosed that acts as a short circuit at only the operating frequency while terminating the track at its characteristic impedance otherwise. Half-bridge and full-bridge power supplies (1101) are described for providing effective amounts of high-frequency AC power to a long primary trackway used for inductive power transfer.

A system for detection of linear underground anomalies passing under surface roads comprises an electromagnetic (EM) gradiometer mounted on a vehicle trailer. A transmitter is mounted to the front bumper of a car or vehicle towing the trailer and provides carrier synchronization information to the EM-gradiometer. An opportunistic radio station can be used as an illuminator. The transmitter or ground wave from an opportunistic radio station directs radio waves down into the ground where objects like linear underground anomalies and their equipment will produce reflections and scattered waves. These reflections will have phase angles and magnitudes that can be interpreted for characterizing information about the linear underground anomalies. Each EM-gradiometer measurement is tagged with GPS location information and then stored in a database. Subsequent passes over the same roadways and tracks are compared (change detection) to the earlier stored data. New linear underground anomalies and features become very obvious in these comparisons.

A toy vehicle trackset utilizes a pair of closed track loops each having a lower end and a raised end. The raised ends of the loops are supported by a raised support having a spring-loaded dinosaur launcher within which a flying dinosaur is supported. A target is coupled to the launcher and positioned in alignment with a pair of launch ramps extending from each of the pathways through a center lap counter which is shaped to simulate a volcano. Within the lap counter, a diverter is supported to switch a moving toy vehicle from its normal loop path to the target directed ramp once the toy vehicle has completed a predetermined number of laps upon the loop by one player. A dual loop hand-operated toy vehicle booster is supported at the lower end return path of each of the loops. The child user is able to crank a hand crank to initiate a manual boost of a toy vehicle. Proper timing of the hand crank is essential to impart maximum boost to a toy vehicle and impart rapid vehicle movement.
