2. Track lighting - Wikipedia

   en.wikipedia.org/wiki/Track_lighting

   The track is powered by a transformer which converts the high voltage into low voltage. There are magnetic and electronic transformers. For all low-voltage fixtures or systems a special dimmer (if used) is required, as standard dimmers cause flickering because of the interaction with the transformers' load characteristics: magnetic transformers ...

3. North American railroad signals - Wikipedia

   en.wikipedia.org/wiki/North_American_railroad...

   There are two main types of signaling aspect systems found in North America, speed signaling and weak route signaling. [citation needed] Speed signaling transmits information regarding how fast the train is permitted to be going in the upcoming segment of track; weak route signaling transmits information related to the route a train will be taking through a junction, and it is incumbent upon ...

   CAF Urbos 3 supercapacitor powered trams operate on the Newcastle Light Rail network with trams being recharged at each stop. The Canberra and Parramatta light rail networks are also planning to introduce battery powered CAF Urbos 3 vehicles on their networks. They will operate on battery power on select parts of their networks. [16]

5. Train lights - Wikipedia

   en.wikipedia.org/wiki/Train_lights

   The discovery of electricity soon led to experiments with using it to power locomotive lights, with the first-known example, a battery operated light, being tested in Russia in 1874. In 1883, a railroad company in France also experimented with electrical lights, but the first example to go into production was designed by an American inventor in ...

   Illustration of track circuit invented by William Robinson in 1872 Track circuit transformer on the right, new axle counter on the left (Slovenia).. A track circuit is an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant signals.

7. Lantern - Wikipedia

   en.wikipedia.org/wiki/Lantern

   A lantern is a source of lighting, often portable. It typically features a protective enclosure for the light source – historically usually a candle, a wick in oil, or a thermoluminescent mesh, and often a battery-powered light in modern times – to make it easier to carry and hang up, and make it more reliable outdoors or in drafty interiors.
