They also consumed a high amount of steam placing a demand on the boiler at the time when the locomotive was working the hardest. Boosters were therefore acquired for very specific assignment.

because that's totally missing the point: the problem is that at low speeds a regular steam locomotive is unable to work its hardest, because it is moving so slowly that the main cylinders cannot use all the steam the boiler is capable of producing. That was the point of the booster; to give a way to use some of that excess capacity. Boosters were especially popular on 'superpower' designs because their huge boilers and massive fireboxes were capable of so much more than they could normally use in the cylinders. —Morven 23:33, Dec 3, 2004 (UTC)
