Re: Converting to DCC

Pete
 

I'll check out JMRI. 
I want a system that is easy to use and doesn't require a huge time sync earning process. I alao don't want to have to be logged onto the internet in order to run my layout. It would have to be a stand alone system that I download to a laptop once then I run it offline.
I'll see what JMRI has to offer,
Thanks, Pete

Mark Gurries is correct in this but I am not sure I got his Other Meaning....In that it won't work all the time, under all conditions.
Could be this is why or as I have learned to say WYE.
A funny thing happened on the way down from the Main Track and further onward to the Turntable and Roundhouse.
(Adding photos to this forum seems to be defunct so bear with me.)
I found I couldn't get there from here ...with anything much longer than a SD-90 Diesel.
N Scale Steam ? Good Luck with that !
Too many Slopes, inclines and switches for the likes of even a 2-8-8-2 to traverse. Bad enough over a #6 but It really brought out the issues in a #4.
This epiphany came after constructing 64 --- 18" x 24" modules....

Then it arrived one day...
in DCC with Sound.
A Hallmark 2-10-4 and it rocked my world.
https://www.youtube.com/watch?v=ls-ulIjy3nU
I began to reconstruct my railroad around it.
Here's the thing...It's not just the size or length of your trucks.
It's the length of your electrified drivers and don't forget the freaking tender two ! 
Can you get the full length of your drivers through each and every turnout on your layout without shorting (or frying) your LokSound Decoder ?
Nor causing the sound chip to weaken with every pass over the frog as in reset ?
======
And learn all over again with longer articulated or not locomotives such as a Cab Forwards. Some Cab Forwards don't articulate too well and then to be stiff along their longitudinal axis.
=======
So....
For now at least....Just how many turnouts are on my in progress layout to fit in an 26 feet by 24 foot room ?
Yes Boys and Girls...That's Feet not inches.
At first...?
None...
I am still working on the four corners with a radius of 28 to 71 inches and setting out the general topography.
The topography alone to depict Northern California when it was all prone to flooding is a daunting task on it's own.
However...back to the drawing board.
I have hand constructed #10's and #12's, along with testing Peco #8's and Atlas #10's while also reworking Kato #6's into #9's and larger.
I have yet to construct a #15 High Speed Rail Crossing which might be my next trick before proceeding.
However.......!?!?!
I am also experimenting with operating them via a servo for an ESU ECoS with Detector electronics as well.
========================
Do I know what I am doing for sure and for certain.....?
I have gone way back to the very basics.
See Forrest Gump and his friend Sheldon Cooper at six years old...play with trains....
I just want to see a Train go round and round...Not glitch, nor decouple with never a decoder reset.
I am getting too old to crawl around on top or under my layout like some 6 year old with his first layout.
To me for now...Switches are like the Electric Arming Switches on our Torpedoes at Midway.

I went to the train show last week, saw a layout bigger than mine running on Digitrax WiFi using cellphones for controllers. Really like that. I have four old cellphones I can put to use and it will save me from buying throttles.

Re: using low voltage on DC fans

Greg Smith
 

Ken
Thank you for the information.  I have a couple of 12VDC fans – think I paid $2.00 for them – so as you say they are not expensive.  They do run on 3.3 and 5 VDC.  Mainly I was curious as to their likely longevity and also to find a use for the 3.3 VDC outputs.   One sure way to find out is to run them and see if they last.  If they do not I will replace with 5VDC fans. 
I am new to this and many basic (dumb) questions are forth coming.
 
Greg Smith
ps – I have checked the voltage output on the ATX power supply and all three voltages are very close to rating.


Re: PSX-AR Installation Query

Mark Gurries
 

This will not work under all conditions.

Any Engine or any car with multiple wheel electrical pickup will still short the two rails together as long as the TRUCK, not just a wheel spans over the gap (insulated rail joint).

So if you engine is crossing the gaps one one end of the reversing section and a passenger car is still crossing the other end gaps, you will still get a short circuit failure.

If you are running metal wheels, every pair of wheels that crosses

if there is a difference, so if your loco hits a second gap before the

again and then the wheels of the cars behind that cross the first gap
will switch the polarity again before the whole train is through
Your AR will be flipping back and forth as each set of wheels hit the
two gaps.

Re: Converting to DCC

Pete
 

Thanks Paul,

I,ve re-gapped my layout as suggested.
I see I will need one AR  for the lower yard.

Can I get by with one AR for the upper isolated section?
(I can't see why I would need one at each end, wouldn't they both trip when either end gets a short?)


I've been reading about dividing the layout into multiple power districts.
Is this something I should consider being that my layout isn't that big?
The upper and lower yards are already sepperate busses. Is that enough?
What more would I seperate?

Thanks,

Re: using low voltage on DC fans

 

The fans are in reality brush-less DC motors and therefore rely on internal electronics to make them rotate.  What happens when you under drive them therefore cannot be predicted.  Some fans are rated to work down to 5 Volts but others don't say.  If you give me the model and part number I will see if I can find its' electrical rating.

These are not costly devices so why not purchase one rated for what you want to do.  3.3V are rare but if you can run at 5 Volts can find a lot of choices.

https://www.digikey.com/product-detail/en/cui-devices/CFM-5010V-052-300/102-4365-ND/7620539

Be sure to check the actual output of your ATX supply as they are designed for heavy loads on the low voltage outlets and may not regulate properly without such.

Re: Reversing Sections.

Excellent point.  And, yes, at least one of my new AR segments is now substantially larger and likely would have two trains on it.
 Hex Juicer will supply 1.7 amps to track.  I believe that ought to be sufficient for two efficient DCC Locos in one segment.  Will put track feeders at regular intervals.

Bill,

Before you get rid of it, there is another consideration. Reducing the number of AR sections often involves making the newly chosen ones larger, or designing them so that entire stations or yards find themselves in one. That is in itself fine and can be crafty, but: keep in  mind that auto-reversers have a current limit that is usually considerably lower than what the regular track power is able to deliver.

Initial AR determination usually aims at smaller sections of single track, and that as a matter of course keeps the current draw in the section smallish. Re-thinks often cause individual AR sections to have to handle more than one train. so if you find the new design does that, have a careful look at the maximum power you expect to draw - and whether the AR can actually provide that.

You’ll be fine.  What you propose to do is roughly the equivalent of running a good old fashion 12 DC motor in an old Athearn engine at somewhere around  27% and 42% of full throttle on that old Power Pack you got with that first train set so many years ago.

Re: Feeder line issues

mgj21932
 

Max, 

I've attached a diagram of the track layout.  One is just a diagram of the track layout (all black).  The second is in color and identifies the individual reversing segments.  (The black siding on the colored version is electrically and physically isolated from the rest of the layout.  It will operate on DC and can be used by grandchildren to operate a switching engine and freight cars.)   The green mainline passes over the blue line via a bridge, as does the yellow siding.  The siding is on a plateau above the blue loop line.  With the exception of the yellow siding, most of the left quarter of the layout is in tunnels under a mountain.  

As you can see, the basic figure 8 design can be reversed in both directions.  That capability is the defining characteristic of the track plan.  

The yellow siding doesn't have to be a reversing section and will probably be wired with the green mainline segment to which it is connected.  Thee is really no need for it to be an AR segment because, with DCC, I can operate a train on that siding independently of what's going on in the mainline; and even if the polarity on the mainline switches, that should not affect operation of a DCC controlled locomotive on the siding.  Had considered wiring as separate reversing segment only to reduce length of 22 AWG feeder lines.

Because of the double reverse arrangment, there are what I would describe as "intermediate" reversing segments that increase the total.  A simple reverse would require 3 segments.  The addition of a second reversing capability splits one of the first three reversing segments and adds another segment, for total of 5.  

The layout has the capacility to run a train on the figure 8 pattern without any switching issues.  Throw a couple of switches and the train reverses; then return those switches and the train continues in reverse around the figure 8.  Throwing a couple of more switches and an almost endless variety of patterns is possible.  I wanted the flexibility for great variety on a small (5' x 9') layout.

I don't encounter any difficulty using 14 AWG directly from the bus on the input side of the hex juicer.  But 15' of 22 AWG feeder line from the frog juicer to the track seems a bit long.  I've asked Duncan McCree (Tam Valley) about that, and have not received an answer yet.  If he tells me that no significant operational issues have been presented by 15' long 22 AWG feeder wires, then I should be in great shape with just 3'-4' of 22 AWG feeder lines from the outputs of the hex juicer.  

Nevertheless, the safer solution might be to splice in a 14 AWG segment from the 22 AWG "stub" wire at the output of the hex juicer to within about 6" of the connection with the track.  The downside of doing so of course is risk of splice failure and possible signal degredation due to the splices.  Do you think that exercise is unnecessary?

The Hex juicers were really intended for   turnout frogs in a dense area like a yard throat. The dual ones are much more suited for scattered reversing loops. (and of course the single ones for isolated turnout frogs)

 

BTW are all  your  reversing sections in the same power district? If not the hex scheme won’t work.

 

To late to do an exchange?

Thought about that Max but 2 Hex juicers were much cheaper than six dual juicers.  So bought Hex juicers to save a few bucks.  Did not realize limit on size of output wires until the Hex juicers arrived and I could physically inspect them.  Live and learn.

Why not use the dual juicers. One per reversing section.

Yes.  All in single power district.  
Planning to address the concern about voltage loss on 3’-4’ feeders by spicing in 14 AWG wire for most of the length.
