We report on the results of the ENACS survey. We show that the regular ENACS clusters are distributed in a well defined Fundamental Plane. We constrain their proper motions to 1000 km.s^{-1}. We constrain the cosmological models by using the density profiles of the clusters. In this way, we show that these profiles are well described by models with a core. We analyze also the morphological segregations in the clusters of galaxies. We quantify the increasing virialization status of the galaxies according to their early morphological type and bright magnitude. Finally, we report about the proper motions of galaxies using the Luminosity Function to correct the order statistic used as distance indicator (cluster proper motions limited to 1200 km.s^{-1}). We compare with the first results of the Bright-SHARC and MPC-CDCS distant cluster surveys (Log N/Log S relation, reality of PDCS clusters)
