  2. Gravity railroad - Wikipedia

    en.wikipedia.org/wiki/Gravity_railroad

    A gravity railroad (American English) or gravity railway (British English) is a railroad on a slope that allows cars carrying minerals or passengers to coast down the slope by the force of gravity alone. The speed of the cars is controlled by a braking mechanism on one or more cars on the train. The cars are then hauled back up the slope using ...

  3. Motorific - Wikipedia

    en.wikipedia.org/wiki/Motorific

    Motorific is the brand name of a line of battery-operated slot car toys and related accessories marketed by the Ideal Toy Company from 1964 to the early 1970s. It differed from traditional slot car sets in that the cars were powered independently by a pair of AA batteries, rather than by an electrical connection to the track.

  4. Total Control Racing - Wikipedia

    en.wikipedia.org/wiki/Total_Control_Racing

    The plastic track had two such lanes, and cars could change lanes with the flick of a switch on the controller. TCR sets came with "jam cars", a slow moving drone which both racers had to avoid crashing into. Like Matchbox's Powertrack, some cars featured lights. The first sets consisted of up to 4 Formula 5000 cars. The track (which stayed the ...

  5. List of rail transport modelling scale standards - Wikipedia

    en.wikipedia.org/wiki/List_of_rail_transport...

    In terms of model railway operation, gauge 3 is the largest (standard gauge) scenic railway modelling scale, using a scale of 13.5 mm to the foot. The Gauge '3' Society represents this aspect of 2 + 1 ⁄ 2-inch gauge railway modelling with both electric and live steam operation. Gauge '3' corresponds to NEM II scale, also known as "Spur II" in ...

  6. Physics of roller coasters - Wikipedia

    en.wikipedia.org/wiki/Physics_of_roller_coasters

    As the car approaches a loop, the direction of a passenger's inertial velocity points straight ahead at the same angle as the track leading up to the loop. As the car enters the loop, the track guides the car up, moving the passenger up as well. This change in direction creates a feeling of extra gravity as the passenger is pushed down into the ...

  7. HOn30 gauge - Wikipedia

    en.wikipedia.org/wiki/HOn30_gauge

    The term HOn30 (and sometimes HOn2½) is generally used when modelling American prototypes while H0e is used for European prototypes. In Britain, the term OO9 is used. [1] All these terms refer to models of narrow-gauge railways built to the world's most popular model railway scale of HO (1:87) but using a track gauge of 9 mm (0.354 in)—the gauge used for N scale models of standard-gauge ...

  8. Track car - Wikipedia

    en.wikipedia.org/wiki/Track_car

    Model car, for use on a toy racing track Slot car, a powered miniature auto or other vehicle that is guided by a groove or slot in the track on which it runs; Safety car or pace car, a car which limits the speed of competing vehicles on a racetrack during caution period or parade lap; Track day car, a road car designed solely or principally for ...

  9. Scalextric - Wikipedia

    en.wikipedia.org/wiki/Scalextric

    It has only one type of straight and corner, and each set can be made up into various layouts; the cars included in the sets are fantasy models, which reduce manufacturers' licensing costs, and a converter track piece is available to allow cars to cross from Start track to Sport and back again.
