Hi! I am investigating the multiple possible methods of lighting coaches/carriages on my HO NCE controlled layout.  I have tried Flicker Free, which works fine.  I have also built small circuits using miniature rectifiers feeding LED strips.  In order to light my entire collection using any of these methods, a significant investment in time and electronic components would be required.  I have tried a small experiment using direct DCC track power to light a short strip of LED lights and found it worked fine, especially with the addition of a 1K resistor in series in the circuit.  Is this approach too simplistic or am I missing something?  Any comments appreciated!  Thanks in advance,

The Bachmann is a good starter set complete with DCC controller and two trains will work nicely on a 4 x 8 it will get you up and running in a hurry but you may get bored with it.
This is such a great hobby, there are so many choices you can make. Just be sure this is what you want, not just for now but down the road. Expandability is limited with the set, its an entry level controller.
See if you can get a demo of some DCC Controllers at your local hobby shop. See if you like the feel, simplicity or expandability of the unit before you make your final decision. If you have decided on a budget for now you can get a DCC Control that you can add to next year and the year after. Building your own from scratch can also give a greater sense of accomplishment or a bigger headache as well LOL
Good Luck

Dan hear, I have both systems.  I started of with a Digitrax Cheif, added radio.  A fiend had a NCE system and I ended up buying the NCE Power Pro with radio, added a NCE Power Cab with radio.  I ended up giving my Digitrax system to my son.  The only thing I don't like about the NCE system is The size of the hand controller. Thats my only complaint.

Different systems cost differ greatly.  One question we need to be answered is how many engines and what scale you are in.  Also do you plan to expand past a 4x8 or not.   If you can provide some more info the group will provide you with a lot more valid of an answer.

Re: DCC journey What is best for your Father's Son?

Mark Cartwright
 

Bruce,


There is one serious aspect of Model Railroading which I have learned by 2014. There are thousands upon thousands of dollars worth of N Scale and HO Scale equipment, sitting in boxes which has never been used or perhaps ever seen a layout; All within 50 miles of this keyboard.   

====> And all I have to do to own it and get it running on my layout TODAY 

= Is show up with CASH. 

This is NOT the same hobby of 1977. Space is a major criteria to any consideration.

============================


A year ago, I would not have attempted to answer your question. However that was over 20 DCC Locomotives ago, some with sound. I am not so sure of any of the above, nor of any of the suggestions. Don't Delay and don't Store it.. Use it - Even if you just loop your bedroom with it along a ceiling ridge.

===

There is something more and it saddens me a bit. 

I have also bought the remnants of at least 7 defunct N Scale Layouts or ones that never even went to the operational stage. Now I am also coming on to HO Scale and just cleared out a large area of my basement for this scale as well. Why? Cause it is nearly FREE.  One day, I also came upon an O Scale Lionel System in the box, like new >> at a Thrift Store (I am running it around the Ceiling of my Bedroom) , and they have their own sort of DCC system, helped along by Neil Young. It's a great system for his son Ben.    

===> Now what is best for your Father's Son?

============================================================================

===> Here is the thing. Don't fret too much about it all. Just do something. Just what ever you can do... >>> Do it! Begin Today. Capri Diem as I like to joke.

===

While I would personally not own the Bachmann DCC system, nor would I even suggest it on any level to friend or enemy.  Oops! My own personal behavior not withstanding > I attended a DCC Seminar at our Local Hobby Shop. Seemed to me at first that the Shop's Personnel  ==== ?Though they all personally use MRC, they were pushing Bachmann.  Why?  This intrigued me, and I began to not only listen but to watch tell-tale signs of behavior. Sort of like Playing Poker. Digitrax seemed to be a bad word and nearly no mention was made of NCE.  It was Bachmann and then Bachmann Again. They even had to take one out of the box to operate it as an MRC system is normally connected to one of their operating systems. For this presentation > They just built a simple oval of track. In fact they went out of their way to make this happen.  Why just not use one of their already built and detailed layouts?   When the seminar was over, (and it was soon over) I milled about and listened to the other participants. Soon it began to make sense.

===  

?? Upwards and over $500 for a DCC System was no where on their customers horizon. It was simply not a target opportunity.  Mentioning CV values would have just confused the lot of them. None of the nearly dozen other participants had an actual operating layout. The room hoped for may actually be in use by another member of their family. Once the kid goes off to school ... kind of thing. Despite this, several Bachmann DCC systems were sold that day.

I mean - Isn't the point of having a store, to stay in business. 

===

So it's your railroad.  If 4 x 8 is the space you have... Then Go for it! And if $129 is in your pocket today. Then just waiting ...? Well don't wait too long.  Start today.

=

I have passed up both Bachmann and NCE DCC systems for under $100 used. I found and bought an MRC Wireless Prodigy for $220.  I will soon come upon a Prodigy Squared system (wired) which I will also buy. Yes, I will buy MRC again and would suggest it to my best friends. I should mention that my MRC USED system, did NOT come with an Instruction Manual.  I use it anyway and have not had  a single issue. It's intuitive to me, and has been a great introduction to DCC.

=

No Reading = No Confusion. I also have been on Macintosh since the Apple I. For some reason, them Other machines tend to break on me or simply not function. Sort of like never been able to get well prepared Grits anywhere outside of the South, that is except if being served on a Train. What works for you may not be the best for Others and location/space may mean everything.

Will all of the above stop me from buying Digitrax? No. I fully intend to eventually, drive myself a bit crazy, by reading one of their manuals. Eventually, I will want to go beyond simple CV programming and delve into JMRI and speed matching with intricate consisting.  So far however, I have not been willing to outbid Others on a Digitrax System. Meaning Yes, there are people out there who chose Digitrax as their first system, then found it overwhelming. Then there are Others, such as myself who upon a good deal will spring for one. 

=

Will I deliberately go running down one day to my Local Hobby Shop and buy a Digitrax System at  or near list price? No. And here is a serious reason why.  They know LESS than I do about DCC as of at least three months ago.  There won't be one once of any help in that MSRP price. There are no schools for their personnel to attend to by Digitrax. None of them own a Digitrax system. Actually, none of them know all that much about installing even a decoder and it all goes down from there. It is much easier to sell a Hasselblad, after you actually own one. 

==

What I will tell you... There is a level to DCC and Computer control with sound - Even above all of this. And it comes with a price, along with words like Loksound and BLI.

:)) Mark



When I was 7 years old, I received my first Train set.  The nice man asked my Father what system would be best for me. O Scale or HO? My Father then turned to me and I boldly stepped up saying HO Scale. Then the little precocious 7 year old began to nearly lecture the  man on why HO Scale was such a better system for our basement.

=

I was destined to then have 4 x 8 layout. However, when my Mother wanted a Ping Pong Table. Meaning at first my heart sank, thinking we were in competition for the same space.  Instead, I was able to go to 5 x 9 with a layout which was lifted up and onto her Table.  Nearly the whole rest of the week, except on Saturday Night when my parents friends would come over - I built my little empire. Especially in HO Scale, yes a 5 x 9 is like a whole other level. That extra foot does make a difference. Yet if you simply don't have it.... don't worry about it  - Start today anyway.


Re: DCC journey What is best for your Father's Son?

Carl
 

Hello:

Another way to start a layout is Modules. You could build four 2x2 corners and two 2x4 straight modules. Each module you build will be better than the last until you replace the first with something better. Till then you can move the parts around to fill any room, or your back yard. This is what I did. I had modules that could build a 14' x 42' with a turntable and a 9 track yard. I ran a lot of trains. Then my dream layout construction caught up to where I needed the turntable. I gave the modules to the local club so they had something to run. I learned a lot and gained many skills.

I have a major Digitrax control system and it works fine for me. I like the size of the UT-4 controllers and they do everything I wish. The radio system is OK too.

Good luck, Carl.

No issues with flickering, or back voltage on DCC.

I have also taken a few LEDs from strips for other applications, and, in a frugal manner, saved the "resistors".
After some of the comments I decided to test these "resistors" and found they appear to be current limiting diode packages.
In one direction they indicate about 5k resistance and in the other direction infinite resistance.
Are these the illusive current limiting diodes we have been looking for for other single LED installations?

At our club we are using a Digitrax system and was having intermittent issues using the Power Pax. We figured out that it would not work using the wireless radio but would work every time if we were plugged directly into loconet. I assume this is probably a Digitrax issue except for the fact that we can program off the programming track using the wireless without the Power Pax connected.

Reality Check Needed - See File and/or Read Description

Rick Allison
 

I'm putting together my first layout in 40+ years-and I have a couple of wiring questions. I've read through Alan's website but have not found an example that matches my situation, so before I build it I thought it best to come here for a reality check.

The layout is a fairly simple 5x9 consisting of two concentric loops surrounding a figure 8. There is a Walthers/Shinohara "DCC-Friendly" double-crossover connecting the concentric loops at the 6 o'clock position, but wiring that should be pretty straightforward. Where it gets tricky is this:

There is also a double crossover between the inner loop and the left-hand lobe of the figure 8, at about the 11 o'clock position. The top of the right-hand lobe of the 8 is elevated over/above the inner loop, and there is a double-crossover between that right-hand lobe and the outer loop at about the 1 o'clock position.

Both of those double-crossovers each use a Walthers/Shinohara curved turnout plus three Atlas turnouts tied together with a 45-degree crossover. (See file HORRTG Layout Polarity Plan.jpg.)

My main question is: With insulating joiners separating the 45-degree crossovers from their respective inner and outer loops, can I use a single auto-reverser (like a Digitrax AR1) between my booster/bus and the figure 8, thereby reversing polarity on the entire figure 8 when an engine crosses over to or from either the inner or outer loops? Or do I need an auto-reverser near each of those double-crossovers? Or...?

Secondary question--although it's a small layout running 3 engines tops, is it worth setting up those two crossovers in such a way as to prevent two engines hitting the reversing figure 8 at more or less the same time (wiring the switches to ensure only one crossover can diverge at a time, or wiring the crossovers with a sensor so that if one is in use the other is de-powered, for example?).
 
Sorry for the lengthy description; hopefully I've got the ''HORRTG Layout Polarity Plan' file or Picture uploaded correctly to better explain what I'm trying to do...

Thanks in advance for your guidance,

- Rick
