Finished RailPro Installation Examples / GP-30 Proto2000
« Last post by LVRR1856 on May 14, 2026, 08:58:18 PM »
Rolling right along - just bought a pair of NOS - P2K GP30's. They were still new in box, never opened.
Of course to be expected on both engines - all 4 wheel gears were cracked. I can change these out in minutes now.
I buy packs of either red or black gears - reuse the old wheels. The Walthers sets are like $7.50/pair ($15/loco).
Just using new gears, can do for about $4/loco.

I pull off the old resistor board, popped in a new set of LEDs with built in resistors, rewired into the 8 pin plug, just a minor file down of the nibs
on the weight where te screws were for the board. LMS-3S set in there nicely along with 9 to 8 harness on one end. (used 1" version).

13mm x 18mm x 3 mm speaker and box from Crude - engineering, fit onto of rear light notch.

No cutting required.

I did run into a short problem. There was a tiny bit of corrosion on top of the 8 pin plug, after several other attemps to fix, finally found it.
scratched it up and cleaned with Isoprop Alcohol ... fixed it. Must have been a reaction from old flux ... good now.

Runs great. Number 2 will get just a LM3 no sound ...

General Discussion / Handheld 2 Frozen
« Last post by rsmproductions on May 10, 2026, 04:58:05 PM »
Yesterday while running trains I attempted to adjust the volume on the handheld.  Went to the adjustment windows and then tried to save only for it to tell me it couldn't because all sounds had to be off and the engine not running at all.  The funny thing was all sounds were off and the engine throttle was 0%.  Tried several times to no avail.  Then I lost all sounds altogether and to run silent.

Then to make matters worse the handheld page froze and I was unable to access any other page and couldn't even turn the thing off...funny thing though the throttle worked and was able stop the engine.  When I was done I just left the handheld alone and let the battery run down.  This morning the handheld was off and there was enough battery to turn the unit on...it was no longer frozen.  So now it is charging back up. 

Not sure if this typical issue because for as long as I've owned never had a problem

Thank you for your thoughts and suggestions.

I don't think polarity of the leads matters as long as all of the speakers are oriented the same way so they are in phase together.

RailPro Specific Help & Discussion / RAILPRO WH-6 SPEAKER WIRING
« Last post by Tom on May 06, 2026, 08:59:55 AM »
Does anyone know which speaker lead in the WH-6 is positive, or how to figure it out?

Also, if dual speakers should be WH-6(+) to Speaker #1(+), from speaker #1(-) to  speaker #2(+), from speaker #2(-) to WH-6(-), what would happen if polarity connections were reversed?  That is: WH-6(-) to Speaker #1(+), from speaker #1(-) to  speaker #2(+), from speaker #2(-) to WH-6(+).

Finished RailPro Installation Examples / Re: Atlas HO C420

If only every model had that much free space to install modules in!

If I recall correctly, DigiTrax harnesses are the crimped wire type. This means instead of cutting / coiling unused wires you can lift the little tab the holds the socket into the JST plug and simply pull the wire and socket out; saving them for reinsertion later if need be...

RailPro Specific Help & Discussion / Anything New From Ring Lately ?
« Last post by LVRR1856 on May 04, 2026, 01:57:31 PM »
Just wondering if anybody knows of any new enhancements or new products on the Horizon ?
Just curious - things seem to be quiet on the home front as they say ...

Perhaps smaller modules ? Software updates ? Added sound files ? ........ Anything?

I know some were complaining about the repeaters not being so good on recent threads ...

RailPro Specific Help & Discussion / RailPro conversion of Intermountain ES44AC
« Last post by Mrpicks on April 25, 2026, 11:55:59 AM »
Has anybody done a conversion of a Intermountain ES44AC that came with SoundTraxx sound /decoder. Our first intermountain loco that was new in the box and super inexpensive. Any assistance will be greatly appreciated. Looks to be a total gut, not a plug and play. At least it already has a speaker installed. Thank you all in advance. Dave

What's amazing is not only how cheap and easily these can be made (I made two for less than $10 each), but how well they work. At 1/5th the cost of the PBM-2, they can run much longer. I was able to use five 3.0v 2F capacitors in series and fit them into my SW1500 in place of the PBM-2 and have room for a larger speaker. And the things never stall. You can also rearrange the capacitors to fit the space.

Sounds intriguing Rob!
Can you take some photos of the install in that SW1500 so we can see how it all fit?
It would also be interesting to see a photo of your home-brew keep alive all by itself so that we can get an idea of how big it is/isn't.
Thanks!
