RailPro Specific Help & Discussion / Re: LM-3S-21 and Keep-Alives - Rapdio Mo'Power
« Last post by CPRail on January 30, 2026, 08:28:21 AM »Hi KPack,
How long of a time "off-power" did the Rapido Mo'Power provide juice in the GP38? I'm seeing just seconds, and that's just with lights and the idling prime mover, no motion. I'd be surprised if it was providing 5 seconds of juice, I'd say more like 2-3 seconds.

Lots of open room in them.
Someday when my wife lets me retire I will have that thing called "TIME"

« Last post by KPack on January 29, 2026, 07:04:34 PM »I installed a LM-21S into a Rapido GP-38 with their keep alive, and it worked great. 5 minute install, including removing and reinstalling the shell. Best install I've ever had.
The model runs perfectly and the keep alive works as expected.

« Last post by Smoke on January 29, 2026, 06:11:08 PM »It appears Rapido has different configurations for different models, as based on this thread on MRH the 44-tonner Mo'Power was able to be used with non-ESU products, but for the D10 there is no fix (https://forum.mrhmag.com/post/rapido-h1644-decoder-question-13640397).
In my ScaleTrains motherboard project, I have spent the bulk of my time trying to figure out the lighting situation, I haven't spent much time with the power pack to see if I can get it to work with the LM. Once I have time, I will be tearing apart a spare motherboard to create an accurate diagram and that should give us an idea on what is actually happening (With the lights and the powerpack).

On the Rapido 44tonner enabling FX6 allows a Tsunami to work with the Rapido Mo Power. Tried the same thing on the H16-44's with no love. On the Rapido D10's there is no fix.

« Last post by CPRail on January 29, 2026, 02:53:03 PM »I saw a post from KPack when the LM-3S-21 was released where he installed it with a Rapdio GP38 with the Mo'Power and he said it worked fine. I'm hoping he'll see this and provide some further insight.
I'll see if I can figure out where Rapido has connected the Mo'Power - you might be onto something there.

« Last post by Smoke on January 29, 2026, 02:24:57 PM »Looks like you will be dealing with a 21-pin install and if the Mo'Power is like the keepalive ScaleTrains uses (Whatever term ESU uses), it has the capability to be turned on or off. It also may not be on the same pins at where RailPro would like it to be.
I'm in the middle of trying to understand a ST motherboard to understand the lighting and the powerpack, and how to get it to work with Railpro.

RailPro Specific Help & Discussion / Re: Different locos, same number?
« Last post by snowdog on January 28, 2026, 09:19:56 PM »If you have more than one HC, just remember that only the specific HC that created the link will be able to "see" the linked locos after the track power has been cycled off/on.
THATS GOOD TO KNOW!!!
