A planetary gear train of an automatic transmission may include a first shaft receiving engine torque, a second shaft parallel with the first shaft at a predetermined distance, a compound planetary gear set on the second shaft including a first rotation element connected to the first shaft through two paths and operated as a selective fixed element, a second rotation element connected to the first shaft through one path and operated as a selective fixed element, a third rotation element operated as an output element, and a fourth rotation element connected to the first shaft through one path, two transfer gears at connecting portions between the rotation elements of the compound planetary gear set and the first shaft, and frictional elements connecting the first, second, and fourth rotation elements to the first shaft and brakes connecting the first and second rotation elements to a transmission housing. |
