Hi Guys,
I posed a few questions to Ring Engineering, and got a response today. I'll post it here in case there is some info that may help someone else.
Hi Joe,
"What is the amperage rating of your sound decoders?"
Our modules are not rated like DCC decoders because our modules are more advanced and have features like short circuit and overload protection. Our module could probably be used where a typical 1.5 Amp DCC module could be used. We are not aware of any loco built in the last 30 years or so that it does not handle. However, we do know that our LM-1 would turn off on an over heat with the blue box locos that had metal side frames. Our LM-2 is more powerful but we have not heard of anyone trying it on one of the blue box locos that had metal side frames. We think the blue box locos that had metal side frames were built over 30 years ago. Our LM-2S does run the later generation blue box (ones with plastic side frames) just fine.
"And are you working on a decoder for smaller engines?"
Our LM-2 module is very small. Below you can see its size compared to a dime. It size is 1.50 x 0.68 x 0.25 Inches.

We believe it can be installed in most all HO scale locos. We have many customers that installed them in small switch engines. In some cases of very small locos a factory board may need to be removed or a part of a weight may need to be cut to provide clearance.
We plan to work on a N scale module in the future. Our N scale module could likely be used on newer locos.
"How many engines can you load into the controller?"
You can load over 100 locos into the controller. We are very confiden that no one will have any needs that exceed what RailPro can do and are confident that the ability to operate large layouts is far superior to any typical DCC system.
"Is this system compatible with the older Blue Box Athearns, or will I need to re-motor and change wheels?"
Yes. Please see below for more blue information.
"Does your decoder come with various instructions for different engines or just one generic description?"
There is one instruction sheet. The installation in most locos is the same. You are welcome to ask us about different locos and we can recommend hobby shops that can install RailPro for you.

Converting non-DCC Ready Locomotives to RailPro
<!--[if !supportEmptyParas]--> <!--[endif]-->
Almost any locomotive can be converted to RailPro. Older DC only locomotives (ones that have no DCC plug) can be converted to RailPro by using the RailPro locomotive wiring diagram and wiring in a 9 pin DCC wiring harness to plug the RailPro module into. When converting DC locomotives to RailPro you need to look out for motors or lights that are connected to the frame. The motor and lights will need to isolated from the frame because often the frame is connected to the track electrical pickup (thought the wheels on one side) and if these connections are not disconnected, the RailPro locomotive module could be damaged.
<!--[if !supportEmptyParas]--> <!--[endif]-->
Beside that you should consider that running a locomotive with a module (microcontroller inside - like RailPro or a DCC module) the electrical connection to the track needs to be good. If the power is interrupted for even a short time the microcontrollers stop to function and need a 1/2 second or so to restart. This is not really the case with a DC loco that only has a motor. If the power is interrupted briefly, the motor slows down but may continue to spin. For example if the wheels and track are dirty, then you get interruptions in power which a DC locomotive may coast through but a locomotive with microcontroller inside may stop and restart. So to get good operation from an older locomotive you may need to make some improvements to the electrical pickup. This need for better connection is basically the same for the typical DCC module or a RailPro module. In fact, most of our customers tell us that when they run their RailPro locomotives on DCC layouts, that the RailPro modules go over dirty track better than their DCC equipped locomotives. Because good electrical connection is needed for locomotives with microcontrollers inside, we only recommend using locomotives with at least 8 electrical pickup wheels. Some older, lower cost locomotives only have 4 wheel electrical pick up (two wheels per side) and they are less likely to run well. Further, it is important to be sure the wheels and track are clean. Also, you will want to remove any debris (such as cloth fibers) from the wheel axles if you see any.
<!--[if !supportEmptyParas]--> <!--[endif]-->
For example one popular locomotive commonly converted to run RailPro is the Athearn blue box locomotives. These need the motor and lights isolated. But also we recommend the following modification to improve the connection form the track to the locomotive module. Removing the strap across the top of the motor and soldering wire to each side of the truck frames and connecting them to the red and black wires as shown in the RailPro module wiring diagram. Therefore the truck side frames will be directly wired to the 9 pin harness so the module is not depending on the sliding contact points which make poor connection for module electronics. The wire used should be flexible stranded wire so the trucks can turn with little resistance from the added wire. You will need to be sure the wire coming up through the frame from the trucks will allow the trucks to turn freely.
<!--[if !supportEmptyParas]--> <!--[endif]-->
Most information out there for converting a locomotive to plug in a 9 pin DCC module can be used to install a RailPro module because RailPro follows the same wiring as the DCC standard. Whatever information you use, just be sure to check the final installation with the instructions provided with the RailPro locomotive module.
<!--[if !supportEmptyParas]--> <!--[endif]-->
If you do the few tips we provided you can get older DC locomotives to nearly run as well as the modern DCC ready locomotives. Almost all newer DCC ready locomotives have all wheel electrical pickup and hardwired connections from the truck frames to the DCC plug.
Please let us know if you have any more questions.
Thank you for contacting Ring Engineering!
Thanks again for the help guys,
