Abstract: Let be a group acting on a tree such that all edge stabilizers are finite. We extend Bestvina-Handel's theory of train tracks for automorphisms of free groups to automorphisms of which permute vertex stabilizers. Using this extension we show that there is an upper bound depending only on for the complexity of the graph of groups decomposition of the fixed subgroups of such automorphisms of .
