BCR or 9vBRLT or what?

Neither. These are Lionel locomotives. the Railsounds boards do NOT have a charging circuit so the BCR is ineffective without the additional $20.00 charging board. The BRLT a Dalee electronics product, is a bit cheaper than the BCR with Charging Circuit but the circuitry is hit or miss if it works or not. Go with tried and true which is GRJ's YLB. IT works plus GRJ, a forum member backs up his product!

Now remember all these prodcuts work with locomotives controlled CONVENTIONALLY, NOT DCS, TMCC, or Legacy. IT's NOT needed for locos running on DCS, TMCC, or Legacy.

Will Hennings have a stock of these YLBs at York in their booth (HH6)?

But of course, I'll have both styles.  For locomotives with a battery cable, the left hand model is what you need.  For newer Legacy with the RS-Lite board and no battery cable, the right hand model plugs directly into the sound board.

Either of these work for conventional or command, they can charge down to around 6VAC on the track.

 That's not universally true.  If you have many of the Lionel steamers with a wireless tether, you can have sound dropouts due to pickup spacing, this has been discussed here in various threads at length.  The whole reason I created the right hand version of the YLB was because of this issue, and they've been brisk sellers.

The Vision Line Niagara and Challenger both have closely spaced rollers on the tender and drop out on many switches.  To avoid this annoying audio interruption, the YLB is the perfect answer.  I've been putting these in most of my Lionel steam with the wireless tether.
