Tom,

I am at the same point in planning. I also plan to go RCBP for my On30 layout. Due to costs, I almost reneged on my decision to not wire the layout for DC or DCC. Since I have a full DCC solution already it was a nice fallback position if I can't afford to go full RCBP.

As soon as I started looking at wiring again, I could see and feel the "blocks" influencing decisions on trackage. Even in a tiny layout (except maybe an oval) we unconsciously take into account possible shorts, reverse loops, polarity, under-layout access, etc. while designing the layout. After much fighting with myself, I have decided I would rather have one or two RCBP locos than a fleet of DCC locos.

I am NOT going to wire for DCC or DC. I will however wire sections in the service areas that can be used for recharge stations (I plan on inside the engine house and side shed and at the water tower). I also will be wiring them to a selector so that only one recharge station is active at a time. This doesn't seem to be needed with S-Cab as it can recharge off of standard DC or DCC but I don't know that I will be able to go with S-Cab's BPS solution. I can always remove the selector if I do go with BPS.

Tom H. and all - I had read somewhere about changing from one loco to another and having that engine take off.  I probably missed an important detail about this problem but it made me wonder if there were other things to consider when sharing a throttle between locos.  
- Tom H. - Tour comment about charging stations being located around the layout got me thinking about my own layout design.  I have three water tanks scattered around and should probably make a short section of track in front of each tank for charging.
- Tom
P.S. - I found where I read about the engine taking off on Stanton's web site.  The problem has already been solved.  See below.
"I do not use the same throttle for multiple locos; each locomotive has its own throttle. I found while testing the switcher that the original unit took off because I forgot to enter the switcher's decoder address. I warned Neil that this would continue to be a problem and he provided a replacement chip with software changes so that each throttle switches on with a specific locomotive address already selected."

The reason I recommend wiring a layout for conventional running is that if you acquire a conventional power loco and plan to modify it to battery power or wireless RC, you have the option of first running it as received to make sure that the motors are good and everything else is intact. Better to check than be sorry later.

But Bob, couldn't you make up a test track some four to five feet in length to test a locomotive?

Besides running wire, there is a sizeable investment in a Digitrax system in order to provide for DCC.  Then there is still the cost of purchasing the BP/RC equipment to operate.

Having gone wireless three years ago, I (just me personally) could never entertain the thoughts of running wire again because things have worked out so well.

I'm sure you're going to love battery power.

All this to say, that earlier today I was running wire for two tortoise switch machines - ha ha

Wiring for on track charging would not be a problem as my fiddle yard is often modified.

I test DC locomotives prior to conversion using a rolling road

I use analog/digital for my point control, a finger or a wooden stick with a loop on the end. A 150mm thick blue foam baseboard discourages switch machine excavations. If I was going to use point motors I would use Peco solenoids. Many DCC users don't use DCC for point control, other methods are available, wire in tube etc.

OK, good advice.  I have a test track in my shop that will work well for that.  I'm using it to practice laying track, scenery modeling and also as a switching game and for programming.  I can power the track or run it dead rail.  The layout will be strictly dead rail except for the battery charging tracks.  I built this test track because I have zero experience with any of these things and didn't want to practice on the layout.  Hopefully I'll be able to hide my mistakes in the shop instead of having do-overs on the layout.

Tom,

You never fail to impress. Your "test track" is bigger than my layout!

On a more serious note, I'm not sure that practicing technique off the main layout is allowed. We are supposed to put our foibles and follies out there on the mainline for all to see. It helps keep us humble.

The point about using a short section of track rather than a full layout to pretest locos is well taken. I have done both and either method does the job. I am currently studying ways to recharge batteries on track. Not as simple as it might first seem.

How does the Stanton system charge multi-cel Lipo Batteries from the track?  How does the balancing work out?  

Or are different types of batteries other than Lipo's used?

Rick,

Stanton does not use series-connected LiPos, it uses parallel-connected LiPos so balancing is not an issue. The BPS has the charger rectifier and regulator built in. The standard regulator output for the BPS is around 11v but you can specify other values. To my thinking, 1S battery solutions are the only practical way for on-track charging. The 2P gives you nearly the same power as a 2S solution. You trade a little efficiency for more practical charging.
