RailPro Installations / Re: I need help!
« on: March 11, 2019, 05:48:25 PM »

I believe https://www.traintekllc.com will be able to install RailPro products.  They are a RailPro dealer as well, and I've found their pricing to be competitive.  It's been awhile, but I had a phone discussion with one of the technicians (Gary, I think) who was very helpful.  Fortunately, I did manage to complete my space-challenged installation, but I would use their services without hesitation. 

Good luck!

the only significant drawback that I find with RailPro is the small number of steam sounds available.


I have about 40 steam locomotive models of all types, but until Railpro significantly expands its sound library, I will defer ordering more LM3s.  I've been following this forum since it started, but so far the sound upgrades seem limited to diesel prime movers, bells, whistles and barking dogs.  I truly hope the
system becomes more useful to the pre-diesel modeller, because in all other aspects I consider it superior to anything else on the market.

Incidentally, when I first got my Railpro, I had to call Tim Ring for help on a weekend:  He answered the phone himself and was VERY gracious and patient.  Hard to find customer service like that anywhere these days!

Michael:

Thanks for your kind reply.  I too am in slow-mode, since I have to build the train room before I can build the layout.  My simple 5 ft. test track on a shelf just isn't very interesting (sigh).  I too have faced difficulty with installation, but that is due to my inexperience and to the very tight space inside a P2K SD9 shell.  After finally getting it all back together, it ran intermittently, so I had to re-solder several wire splices: success!

I am also waiting for better steam sound files before cutting out the factory electronics from my fleet of boiling-water locomotive models.  Maybe, like you, I'll settle for a mix of Railpro  and DCC.  Fortunately, I'm in no rush.  Nonetheless, I look forward to reading more of your progress.

Bill:  Thanks for the tutorial: definitely a better (lazier) way to quote!  I hadn't noticed the cartoon balloon icon before.

Just click on where it says “quote” on the right side of the post you want to quote. A text box will open. Type your quote just below the quoted text in the box.

Or do what I just did (with Windows 7): click "Edit" on upper left toolbar, then highlight the desired quote, "copy", then open a reply (dialogue box) and "paste."  I am a slow typist, so this works better for me.  Maybe someone knows an even lazier (better) way?

Has anyone heard back from the author of this thread as to whether (and how) his installation problem was solved?  I realize this is an old topic, but I found the discussion very interesting.  Unfortunately the author, melarson, does not appear to be on the rpug member list, so I'm not clear how to ask him/her directly.

Lee:

Your thoughtful note was very encouraging, certainly not "rambling."  Although I am years behind you in experience (I am still awaiting the contractor who will renovate my attic for a large train room), I have already accumulated a large roster of locomotives, and intend to do as you have.  I will read with interest your ongoing progress and insights.

Bill: That makes sense to me, with the KA capacitor protected (from track polarity reversals) by the bridge rectifier. Your new diagram shows a LM-2, but I presume a LM-3 (or any track-powered device) could be wired in this manner.    Since the bridge rectifier in this schematic handles the full locomotive current, I expect it will require a higher current rating than those used in light-only circuits.  I would appreciate any current information ;) you could provide on these specifications, as I am considering this approach for my installations (and that "Magic Smoke" is SO expensive!)

Alan: Does this configuration mitigate the concern about shorts you referenced in your May 12 comment?

Jim

Thank you, Alan. That clarifies my misperception.  Am I correct in assuming that the capacitor (KA) as diagrammed will only provide relief from light flicker, but not sound or motor?

Jim

Alan, I am puzzled as to why the addition of a bridge rectifier to the light (blue) common would result in a voltage drop to the motor circuit?  Was Kevin's installation different from Bill's diagram above?

Please excuse my ignorance if this is a stupid question. My brain circuits for electronics are obsolescent, since they were wired 40 years ago!

I just noted a new RailPro thread on MRR's website under 'electronics and DCC'.  In view of the preceding discussion, perhaps it would be beneficial for someone with more knowledge than me to help that (widely read) forum give a better description of RailPro to it's readers.

I thoroughly agree with your goal of promoting RailPro, both for the benefit of the modeling community who are unaware, as well as for the benefit that increased use will serve to keep this innovative control system available for those of us already committed.

RailPro Discussion & Help / Re: Install in a P2K S-3?

I'll second that.  It would be really helpful to see some photos and comments about your approach.  I've been trying to solve a similar tight installation in an SD7 (my first), but I think yours is probably even more challenging. I'm really glad I'm not doing N gauge!

Your history of the SD7 verifies the adage "truth is stranger than fiction."  That would be a really nifty scene to model the C-C powered flatcar/F3-unit/caboose test scene.  Are you aware of any photographs or movies of the test units?

Tim:

A photo (but not the interesting embryology) of SP1518 (currently at the Illinois Railway Museum) is on Wikipedia.  The article states it is the first of its class, and hints that it is slightly different from its successors.  Perhaps an update to the article could be of interest?  I would never have guessed your answer!
