A gear train is a set or system of gears arranged to transfer rotational torque from one part of a mechanical sytem to another. NOT a rail stub (or at least the railway icon should be changed) A gear is a toothed wheel designed to transmit torque to another gear or toothed component. ... The concept of torque in physics, also called moment or couple, originated with the work of Archimedes on levers. ... Mechanics refers to: a craft relating to machinery (from the Latin mechanicus, from the Greek mechanikos, meaning one skilled in machines), or a range of disciplines in science and engineering. ...

My Use of Lego Gears (1175 words)
There is a lot of friction (destructive friction) between a worm gear and the gear being driven by the worm gear.
With worm gears, the surface of the helical teeth slide against the radial teeth of the spur gear (24-toothed, 40-toothed, etc.).
Gears of the same size will vary in strength such that one set of gears may fail in a given situation, whereas another set may hold up.
Howstuffworks "How Gear Ratios Work" (275 words)
Gear trains often consist of multiple gears in the train, as shown in the next two figures.
In this train, the smaller gears are one-fifth the size of the larger gears.
That means that if you connect the purple gear to a motor spinning at 100 revolutions per minute (rpm), the green gear will turn at a rate of 500 rpm and the red gear will turn at a rate of 2,500 rpm.
