I fought the Free-mo DCC demons as best as I could and lost, miserably. DCC is ingrained into that module standard, and most of the hobby, for better or for worse. I'll be purchasing a DB210 to power my module set (it has two distinct power districts; main and non-main) and I've already ordered the DCS52. I'll use DCC power on my module set from here on out, even at home, in order to dial in the current detectors.
I'll also be going a step further and equipping all of my SW fleet (3 units right now moving to 5 eventually) with DCC sound decoders instead of RailPro. The reasons are three fold; first, Ring hasn't released anything small enough yet to fit into such a small locomotive without major surgery; two, the major benefit of RailPro's load sharing isn't utilized in a single SW switching cars; and three, most of my operators will arrive with a DCC throttle.
All of my road locomotives will remain and/or be equipped with RailPro. I don't ever want to bother with speed matching ever again. It also appears that thanks to Ring that Digitrax has finally entered the early 2000's with the UI. Yeah!!

That's sad to hear.

or stubbon, brainwashed, clueless, biased... I could go on.

More than likely it was TCS's offering not RP that pushed them to do it if it was competition that got them off their backsides unfortunately.

I have successfully installed LM-3S modules, speakers and Keep-Alives in both a Rapido SW1200RS and a P2K S3, both without major surgery. You have to toss the board in the SW1200RS, but it can be done.
I've posted on RPUG pics of the SW1200RS install and a description of the S3 install (forgot to take photos) posted as well. If I ever open up the S3, I'll take photos.
RP can be put in these locos, you just need to think it through. On the radar are two Rapido GMD-1s, but I've taken a break from tight installs for a while.

Has anyone here done an LM install without the plastic shell? That would buy a little more room.

without the plastic shell?
Yes, Alan has done that. You can wrap the LM in Kapton tape to protect it, but be aware, removal of the casing is likely the end of any warranty on the unit.

I did. The tiny amount of horizontal space saved by removing the plastic case was just enough to get the module to fit inside the hood of a HO Atlas S-2. Wrapped it lengthwise with a single layer of Kapton tape.
Fun fact... I emailed Ring alerting him of the fit solution. Tim responded it was a fire hazard. He seems paranoid of being sued or styrene is now considered a fire suppressant. ;D

Most DCC boards are bare to begin with.
I'm guessing cooling would be best if you left it unwrapped, you'd just have to be mindful of potential shorts.

Yeah, I'm sure shorting is the real concern. Just found it illuminating (funny?) that Tim leaped all the way to fire hazard instead of a more practical be careful of shorts reply.
Reminds me of the assembly instructions that used to come with Trek bicycles. Big bold warning "Not following this instruction may lead to injury or death" appeared on virtually every step throughout the instructions. It must have been in there 30 times. Apparently people are dying in droves from improperly assembled bicycles. Lawyers, gotta love'em.

Absolutely.

On a more useful note... modules do employ CMOS technology so they are sensitive to static discharge. Don't handle a bare board without first properly grounding yourself. Standard CMOS rules apply to an unwrapped module. Touch grounded equipment or grounded plate immediately before touching any of the individual parts or the printed circuit board.

Any manufacturer designs and builds its products to be used in a designated way by the customer. The LM packs a lot into a small package. I am sure Tim has fire-tested the LM casing and seen a benefit. Better the LM melts than an open flame ends up consuming the loco, the layout, and the room! I experimented with battery power for trains and a short caused a small flame like a cigarette lighter to pop up on my micro r/c receiver. (Even small LiPo batteries can output significant amps when shorted.) Luckily, I had the shell off and only the Rx was damaged.

I have a few DCC sound decoders that I never got around to using before I went all RP. Care to make some kind of trade? Darryl

I know the new TCS throttle works across different DCC systems, but I question why they would put the resourceas into developing new hardware when smartphone throttles are the cutting edge for control -- and yards cheaper.

Why are you asking me? I'm not the one going back to DCC :)

And you only have to read a few of many forums posts out there on the world wide web to see what a lot of people think about using phones as throttles! Just like there is still plenty of DC only people out there there's a great deal many people where using a phone as a throttle is just not 'gonna happen. I've done it and don't particularly care for it.
As to the cost being yards cheaper, well comparing apples to oranges maybe, comparing apples to apples no. I'll leave the rest of your post well enough alone.

I ultimately came to a similar conclusion. I've started construction on a permanent layout, which I too will be powering with digitrax equipment. My decision is based on a couple reasons. One: Its cheaper than using a series of Ring power supplies, although it does not rival the power method put forward by Alan. Two, I'm alone among my friends in the Railpro venture, DCC runs strong with them. By having a DCC power supply, they are able to run something of their own. With the newish Wifi interface that Digitrax has, I don't need to invest in DCC throttles. Third, realistically I will never convert my entire fleet to RP. I own somewhere over 100 locos, many already have DCC. It would not be cost effective to convert everything. Also, as Jacob mentioned, there are cases where conversion is basically irrelevant. For example, I'm planning on a solo RDC run for my layout. It would be just as effective to pony up the minimal cost for a sound equipped Rapido than go through the hassle of buying a DC, converting, then never consisting it to anything. Especially when there aren't really any correct RP sounds.
I really think this arrangement covers the best of both worlds.

Alan--what is the purpose of the resistor?
thanks

Safety. Prevents possible spark when metal plate is touched. Also provides protection should a voltage source accidentally touch the person or plate.
Imagine your elbow is touching a plate with no resistor when your hand touches an improperly grounded cabinet of electrified equipment. The water in your arm is of sufficiently low resistance that it allows full mains current to flow from the equipment case through your hand through your arm through your elbow through the plate to the grounded outlet. You get electrocuted.
Adding the high value resistor to the case/hand/arm/elbow/plate/outlet circuit limits the current to a fraction of a milliamp. You feel nothing.
It is important to dissipate static electricity by being grounded but at the same time you don't want the ground path to be able to carry lethal amounts of current.

thanks for the explanation!

Hmmmm Maybe this would help as I grab the metal door frame and open the door. I get a zap but strangely only during the winter? Wife gets the same thing or if we walk and touch each other. No carpet, just tile flooring. Weird eh? TOF
