rdg,
Regarding the addition of the LionChief app and bluetooth control of engines under command control * consider this:
a.) CAB-2 with Base 2 currently provides the most detailed control of any Lionel (Legacy, TMCC, or LionChief+ or LionChief 2.0 product, but not plain LionChief product) or other TMCC product.
b.) CAB-1L with Base 2 or Base 1L accesses fewer features in the Legacy feature set but operates many of them. It accesses all features in TMCC or LionChief 2.0 product, but not plain LionChief or LionChief+ product.
c.) Bluetooth control also accesses fewer features in the Legacy feature set and operates many of them, but only if the Legacy product has bluetooth control installed in it; since the beginning of Legacy most do not, but most new ones over the last several years do. It accesses all features in LionChief+ or LionChief 2.0 product, but not plain LionChief product, again only if the corresponding product has bluetooth control installed in it. Notice that TMCC is left out of this list.
d.) CAB-1 with Base 1 accesses even fewer features the Legacy feature set but operates some of them. It accesses all features in TMCC, LionChief+ or LionChief 2.0 product, but not plain LionChief product.
e.) LionChief controller accesses no features the Legacy feature set and so operates none of them. Ditto for TMCC. It accesses all features in LionChief, LionChief+ or LionChief 2.0 product though, as well as plain LionChief product.
Confusing? Yes. Workable? Yes. Which specific features for which method of control? This seems to be largely dependent on the locomotive. As far as I can tell there is no tried-and-true list that you can depend on before you buy.

* I have purposely left off running any of these in conventional mode because this summary is bad enough as it is. You can always operate any of the above, other than plain LionChief, by varying the track voltage in the old-fashioned way and get the smallest number of features.
I've also purposely left off the LionChief App. Until recently I've had no LionChief or bluetooth controllable products but I've just received a LionChief+ steam switcher and a LionChief 2.0 F3 set. I have not used the app with either yet. Additional comments may be coming soon.
