Both cylinders are spaced 84 in. betweencenters, whereas in the lighter Mallets the spacing is 85 in the case of the 2-6-6-2 Mallet the Mellin type ofby-pass and intercepting valve is used to control the simplingand compounding of the locomotive. In tlie matter of general design the crosshead for the2-8-8-2 locomotive is the same as that of all standard loco-motives. The di
