It is essential to have two coupled gears of different sizes on the intermediate layshaft. If three gears were used the overall ratio would be simply that between the first and final gears the intermediate gear would only act as an idler gear: it would reverse the direction of rotation but not change the ratio.
An intermediate gear which does not drive a shaft to perform any work is called an idler gear. Sometimes a single idler gear is used to reverse the direction in which case it may be referred to as a reverse idler. For instance the typical automobile manual transmission engages reverse gear by means of inserting a reverse idler between two gears.
In some parts of the world road rollers are still known colloquially as steam rollers regardless of their method of propulsion. This typically only applies to the largest examples
