A gear train for 6-speed automatic transmissions used in vehicles includes a compound planetary gear set, realized through combining first and second planetary gear sets in a radial direction, the second simple planetary gear set being enclosed by a ring gear of the first simple planetary gear set, the ring gear able to act as a sun gear for the second simple planetary gear set, and having five operational elements. A clutch assembly is mounted between at least three of the five operational elements of the compound planetary gear set and an input shaft, and operates to select the operational elements to be input elements. A brake assembly is mounted between at least three of the five operational elements of the compound planetary gear set and a transmission housing, and operates to select the operational elements to be reaction elements.
