We analyze the galaxy properties of 3 intermediate-z clusters, CL0048-2942, CL2245-3954 and CL2249-3958, searching for environmental effects. Member galaxies of the first 2 display very similar cluster-centric radial gradients in stellar populations and spectral classes; this is interpreted in terms of galaxy infall into the cluster, followed by truncation of star formation and passive evolution in luminosity. CL2249-3958 is a particular case, since it is a poorer system apparently made up of 2 sub-clumps infalling into one another along the line of sight.
