Short explanation, I am sure that Ed can provide a better one. Using
spent steam from the locomotive ( like in a mallet), you add one or two
trucks with pistons to power the wheels on the tender. This in theory
adds more tractive effort, it does when the tender is loaded. When the
tender starts to empty, it is not an advantage, see the triplex locomotives.
