R160s 8843-9102 have the Siemens.
All Alstom built 8313-8712 & 9233-9802 & 9943-9974 and Kawasaki 8713-8842, 9103-9232 & 9803-9942 have the Alstom version and can intermix with each other.
R211s, as you mentioned have that never seen before Alstom Optionix, which is brand spanking new.
I wish the next round of orders will have the classic propulsion {similar to the IRT SMEES before the Redbird rebuilds} OR the Triple Metals (R38, R40 & R42) propulsion of the late 60s.
