A baffle train for turbine generator air baffles independently aligns axial position of the composite air baffle along a stator core bore axial slot. Air baffle sectors that form the composite air baffle are coupled to baffle blocks of the baffle train. The baffle blocks are positioned axially along at least one axial spacer rod corresponding to the desired position of the composite air baffle within the stator bore. The baffle blocks are locked into position by a locking engagement member. Wedge blocks are axially spaced on a reciprocating wedge block rod within the stator slot below the baffle blocks. A biasing element, such as arched leaf spring, tensions the baffle block radially inwardly toward the stator bore when the wedge blocks are reciprocated below the baffle blocks.
