In the 1960s, TYCO changed its focus from train kits to ready-to-run trains sold in hobby shops and added HO-scale electric racing sets, or "slot car" sets. A wide range of slot cars and repair parts, track sections, controllers and accessories were also available. The slot car rage started in 1963. [3]
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 ...
Europa's gravity is approximately 13% of Earth's. The temperature on Europa varies from −160 °C at the equator, to −220 °C at either of its poles. [145] Europa's subsurface ocean is thought to be significantly [clarification needed] warmer however. It is hypothesized that because of radioactive and tidal heating (as mentioned in the ...
The first sets consisted of up to 4 Formula 5000 cars. The track (which stayed the same throughout successive generations of cars) was wide enough for two cars side by side and had raised edges along both sides to prevent the cars from leaving the track. No more than one or two cars could be controlled and raced. They were controlled by the ...
A module with 620mm of track is referred to as a "double". Those with 930mm of track (3 x 310mm) are known as "triples" and, there are "quads" (4 x 310mm) and even longer T-TRAK modules for special situations. It is advisable that all track on straight modules be built as a multiple of 310mm units of track for reasons of compatibility.
Europa Clipper is designed to follow up on evidence for a subsurface ocean underneath Europa's ice crust, found using the Galileo spacecraft which orbited Jupiter from 1995 to 2003. Plans to send a spacecraft to Europa were initially conceived with projects such as Europa Orbiter and Jupiter Icy Moons Orbiter , in which a spacecraft would be ...

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 ...
