Not sure which it is. It's on both axles. Reading C430. Good option in HO? Thanks.  |

Detail Associates 2808
Details West WS-350
I have 3 or 4 different axle generators I will be doing in my line in the next month or so, this being one of them.

I believe KV is in the process of making them as well, if i remember what Scott said at Springfield correctly

The Details West part looks undersided when installed. These photos show the part (WS-350) installed on a Bowser C630 sideframe. Not sure why Bowser didn't invest just a bit more money into tooling a separate part that accurately represents a wheel slip detector for their Alco models. I think they were a standard part on all the Century series locomotives, so it seems odd for Bowser to not include them. (Sorry for the crappy photos, I took them over 5 years ago when I was asking about this part on ARF.🙄)   You can see in this photo that the Bowser axle cap is a separate part from the sideframe.  The only model I've seen that has decent looking wheel slip detectors is Rivarossi's U25C. The ones that are cast on the sideframe of new Atlas U30C look way undersized. It is such a prominent detail and yet only one manufacturer got it right out of all the ones that offer Alco models. My hope is that someone will offer this part in 3D resin. Ideally, they could also make a retrofit part that replaces the axle cap on Bowser sideframes so all the modeler has to do is pop off the old cap and replace with the resin part. I would do the research and design work myself if I knew how to use the available software like Fusion 360. The Reading Railroad Museum is not far from where I live and they have several Alcos in their collection so field measurements would be a piece of cake! Thanks Mark J. Reading PA |

The problem with most of these wheel slip detectors is the lack of a cable. The Detail Associates part does have a tiny pin allowing you to thread on a piece of insulated wire, but the pins are incredibly easy to break off. It’s not a task I much enjoy, and for a six-axle GE or Alco, you get to do it six times. I agree the Rivarossi part is nice, and I recall one of the Proto 2000 models (RS27 I think) also had some nice ones. Too bad none of those are available separately.

 DSC04155 (2) by wp8thsub, on Flickr I sometimes use the Detail Associates parts. The plastic pin intended for attaching the cable is annoying and fragile, so anymore I typically cut those off and drill so I can insert the wire from the cable into the part. If I can find the old Utah Pacific brass equivalents, I use those by soldering the wire from the cable onto them before adding to the journals. Those are nice and durable. |

The cable on the RDG unit is almost a curly mess. Maybe thick thread?

Reading PA Yeah, it looks way too small, the flip side is the journal also looks too big. The "base" of the "cone" should be large enough to cover the journal. It looks like its barely covering the bearing.  Another view here: www.flickr.com/photos/29997762@N05/8592500109/sizes/4k/(Guess what I measured today!) |

Oooo, you will definitely have to let us know when these are available!

Yes, the Bower high adhesion (Hi-Ad) C630/636 sideframe is far from perfect and if I recall correctly, it received some criticism when the C636 models were released in 2014. To be fair, the tooling was pretty good for the time, and as shown in my photos, it is relatively easy to disassemble for paint and detailing. Thankfully Bower didn’t make these out of Delrin. However, someone with good CAD skills and a decent 3D resin printer should be able to make a much better version now.  12bridge, if you are planning to make the wheel slip detector to add to your parts line, PM me and I can send you my extra Bowser frames so you can check the look and fit of your part on them. Heck, I'll send you my extra trucks too if you want to tackle making new Hi-Ad sideframes! Mark J. |

Thanks Mark. I actually have a set of those side frames downstairs. The issue I am having (and this holds true with a lot of parts)..
... Do you A) keep the part 100% scale, which I prefer to do or B) shrink/enlarge it to fit specific OEM's, in this case lets say Bowser. But the part would not fit on an Atlas, so on..
We shall see. I have the first 6 axle generators/speedometers drawn and the test parts are printing as I type this..

The thing that bugs me about the Bowser Canadian C trucks is that the brake shoes are nowhere near lining up with the wheels. Don't know if the American Hi-ad is the same.

Here is the first test shot of the Alco/GE style axle generator. This is one of 6 axle generator's I will be announcing at St. Louis. Still a few things I am going to tweak.  Walthers Proto AAR B  Bowser Alco Hi-Ad |

Looks fantastic. How do the wires attach to the recorder?
