There are two types i=1,2 of particles on the line R, with N_i particles of type i¸. Each particle of type i moves with constant velocity v_i. Moreover, any particle of type i=1,2 jumps to any particle of type j=1,2 with rates N_j^-1_ij. We find phase transitions in the clusterization (synchronization) behaviour of this system of particles on different time scales t=t(N) relative to N=N_1+N_2
