YES

This TRS is terminating using the restricteddeltasimple interpretation 
0(delta5) =  + 2 + 0*delta5
g(delta4, X3) =  + 0*X3 + 0 + 2*X3*delta4 + 0*delta4
f(delta3, X2) =  + 0*X2 + 0 + 1*X2*delta3 + 1*delta3
g_tau_1(delta4) =  + 1(delta4/(0 + 2 * delta4))
f_tau_1(delta3) =  + 1(delta3/(0 + 1 * delta3))
