Converting Rapido RS11 from Loksound to TCS WOW Diesel

Hi everyone, thought I’d share my journey on this model. First off, I think Loksound decoders are great and I have a handful of locomotives running them. That being said, this particular example had a few issues that I wanted to address and converting to TCS seemed to make the most sense.

  1. Current pickup was / is abysmal. I don’t have an explanation for this, but this thing will not make it around a sharp curve, let alone a turnout, without cutting out at least the audio. All efforts to clean the wheels, make sure I have at least one truck that can rock side to side, and check that both trucks pick up current did not improve things. So I wanted a keep alive, which meant I needed a new motherboard. Yes, I believe I could have added a KA to the Loksound setup somehow, but #2 below still wouldn’t be solved. Here’s a video that I took while trying to troubleshoot the pickup issues.

  2. The sound quality of the prime mover was not awesome. Beyond notch 4 or so, it just turned into white noise; it could have been constant radio static for all I could tell. Maybe this is prototypical, maybe not, but it just didn’t add much to the experience.

  3. The sound volume itself was very low and was drowned out by the sound of wheels on the rails at anything over medium speed (and I configure my locos to top out at less than half speed usually). I wanted to try a different speaker.

Parts list:

  • TCS WOW-121 Diesel 21 pin decoder
  • TCS AS-MB2-NC motherboard (this is for Atlas, but it is almost exactly the same size as the OEM board)
  • TCS KA1 keep alive
  • TDS Supersonic Mini speaker
  • Mr. Super Clear flat spray (unrelated to the items above, but I don’t like shiny locos)

Rapido packed a crazy amount of lights into this thing: two different color directional ma

I congratulate you, that is quite a project. Links to google photos work for the OP and sometimes for others, but not consistently.

I can see your videos, for now.

I don’t see a link to the OEM speaker port picture.

None of the pictures are showing for me. I’d be interested in seeing the conversion …

Mark.

I’m nothing short of astounded that you needed a “keep alive” for a Rapido diesel! I suspect the real problem is their super-super-detailing has caused there to be something obstructing the truck from moving freely on curves. I hope you contacted Rapido before doing all this work; if there was something wrong they may have wanted to see it so they could correct it in future runs.
