Reply to "LC+ Camelback Upgrade to Battery Power"

Well, the Camelback is done.  Actually, it was very easy, I repurposed the chuff on/off switch to switch between track and battery power.  Stuck the battery in the tender with a charging jack and used a 2-pin tether to bring battery power to the locomotive.   It fires right up and runs on dead rail.  Speed is reasonable and sound is fine.  On the test blocks, running at 10 volts DC, the locomotive only draws around .5-.6 amps when you put a load on the drive wheels.  Judging from that, it should have fairly long runtime on batteries.

The bad part is, 9.6 volts is probably marginal for this task, at least with the LC+.  The electrocoupler doesn't work, if I power the track with around 14 volts DC, the coupler starts working.

The other problem is smoke doesn't work at all with 9.6 volts, again it required around 17-18 volts to get smoke from this engine.

In case one wonders, I tested using a bench DC power supply to see what it takes to get full operation as well as to monitor current draw.
