LC+... a very basic question

If you have two of the same LC+ engines then they can be run with the same (single) remote. 

I fact, you want to have only one remote on for the both.  Don't confuse them.  I ran a nice lash-up of two GP7s that way.  The only problem you might get into is, if you have the pair coupled and want to de-couple the train behind them with the electrocoupler, activating it on the remote will activate it on both locos.

Agreed. Which is exactly what I posted above about my own experience and interest in LC+. Conventional operator only of mostly PW Lionel so I have no interest in TMCC/Legacy.

Here's another facet of LC+ that has appealed to me (so far, at least). Two of the recent offerings (the NW-2s and the E-33 Rectifier Electrics) harken back to the PW days and I was immediately interested when I saw them in the catalogs. They are also offering FT AA sets in the 2015 catalog. Hoping for some F3s next time.

Do you not then get sound out of both engines? I guess you could turn down the sound in one of the engines.

A little to add on GGG's post above:  

Basically you are discounting the capability of the technology based on it's current implementation.  When it comes down to it yes, as it is currently offered, legacy is better for a whole railroad, and LC runs single engines, however, that is not because the tech can't handle it, but because the marketing is better to not to cut into an expensive system you are trying to push.  There is no upside to cutting into your own market that has fiercely loyal customers.  Had Lionel wanted to, they could replace the track signal in Legacy with the same 2.4GHz transceivers used in LionChief, and kept the system otherwise identical but without the problems of a track signal.  As far as cost, currently there is no practical difference between a 455K and 2.4GHz board, though for a one off hobbyist, the 2.4 is easier to find and much cheaper. ( $1.50 vs. about $5.00)  other than the device used to transmit and receive the radio signal all of the other electronics are identical.  In the end, i'm sure someone made the call that if it wasn't broken, why fix it, however I would be very surprised if the next generation control system doesn't use 2.4GHz or 5Ghz radio.  Implementation for backwards compatibility could be easily accomplished in two ways.  To give the most access to features you would pop out the R2LC(or Legacy equal) and replace with a new module that receives commands directly from the new base, or the second option would be a module that connects to the track and relays commands over the 455k track signal.  

Also as far as two way communication, this is built in to mass produced 2.4Ghz modules and takes the same amount of code to turn off as to use.  

Guess the point of all this is, the LC+ tech is not in any way inferior to that used in Legacy/tmcc, it is just specifically designed not to compete at this time.  

Actually, if you run real prototypes, you get sound out of both engines too.  Unless you're a fan of crewtalk, it sounds great.  When I MU multiple locomotives, I always enable sounds for all of them, really sounds very neat!

Yeah, I was thinking more bells and whistles! I thought on the real thing the bell sounds and horn only came from the lead engine. It might sound cool with both of them though.
