A nice thing about LC, LC+, and the forthcoming Bluetooth command control methods is that they are, as far as I can tell, completely oblivious to variations in layout wiring, scenery, track design, transformer grounding, etc., unlike TMCC/Legacy and DCS. And with none of the disadvantages (complex block wiring, operator tied to fixed location transformer) of conventional. No offense to those who love conventional, DCS or TMCC/Legacy, but these are some possible advantages. Other advantages include the ability to be operated on conventional and command layouts along with conventional and TMCC/Legacy/DCS command locos with no modifications to layout or loco. Really no downside, in my personal view, other than the need for another handheld controller (remote, cell phone or tablet for Bluetooth), And a controller comes with each and every set/loco. Of course, the top end locos haven't been available with LC+, but that appears to be changing in the current catalog.
