Re: DCC Wiring - Can it cause a fire?

Hi Steve,

Are you suggesting gaps closer to or farther from the frog?  Could you explain what you mean with a little more detail? Or point us to a diagram or discussion.

Thanks!

<<If there is a highly resistive connection somewhere in the wiring that is more than about 2.8 ohms when using a 5Amp booster and there is a short circuit on the track,  that resistive point is where all the heat will be because the booster will not have shutdown but instead deliver full power.>>

 

A local layout has hand laid track and turnouts with powered frogs.  The original track layers and electricians were not too careful about where they cut the gaps beyond turnouts.  We’ve lost the side frames of two different engines to excessive heat when the front wheel set of the engines spanned the gap that isolated the frog from the yard track. 

 

Good construction minimizes a host of errors – keep those gaps inside the fouling point of your turnouts and equipment and it will reduce the number of problems due to shorts by reducing the possibility of shorts.

DCC Track Design for review

Hi I'm new to the group and DCC but not to the hobby
Its been over 30 years since I built my last layout (a lot has changed since then)
I have been doing a lot of reading & research. I designed a new layout 5 x 8'  the table is built and ready to go (you can see it in the FILES section) "Final Layout for Review" 
I am proficient with auto cad so after I tried some of the available free programs like Any Rail I decided to do it in autocad so I can get may track spacing and radius geometry correct.
I have Purchased Peco electrofrog turn out switch Peco 100 Flex Track its going over an old school cork roadbed and ballast
I have purchased tortoise switch machines as well
I built the Walthers Turntable and its ready for install
The uploaded drawing shows my proposed track layout with isolator locations track feed locations and block identification
I plan on wiring the elecrofrog thru the tortoise as per many online recommendations I have read  
The purchase of the other DCC controls I have not fully decided on, I am planning on building a fascia control panel for switch control as well as control from a handheld throttle. In the future I would like to experiment with PC control using JMRI software (but one step at a time).
I'm welcoming anyone to look at my plan and see if I may have over looked something thus far before a start making things permanent. 
There is a reversing section across the middle that I had concerns about wiring a reversing module

Re: 10 amp booster Re: DCC Wiring - Can it cause a fire?

Mark Gurries
 

V = I * R

Ohms law re-writen to solve for ohms

R = V / I

The equation is setup like this:

Ohms(Wiring) = V(track) / I(booster)

For the 10Amp booster, I(booster) = 10A and Vtrack = 16V (Factory setting)

Ohms = 16V / 10A = 1.6 Ohms per advertised specifications.

However in practice the 10Amp booster puts out close to 12Amps  (Production design margin to guarantee 10amps) which mean the actual real value is closer to 1.3 Ohms.

This is the maximum resistance value one can tolerated from one track terminal on the booster out and around the layout all the back to the other terminal of the same booster.  Your layout wiring should make sure it is less than this value.  Hence the quarter test does just that.  If a short circuit between the rails does not shutdown the booster, you have a wiring problem with to much resistance which in this case means you have more than 1.3 Ohms.

Re: DCC Track Design for review

Chuck, it looks like a good plan.

One question: It looks like you have about 25 separate blocks. What is you plan for these blocks?

n  Individual circuit breakers?

n  Auto light bulbs?

n  Grouping them to a terminal block for troubleshooting ease?

 

The reverse loop shouldn’t be a problem so long as the isolated section is longer than any train you plan to run thru it.

 

Do you plan to be a lone operator or have multiple operators?

I will probably tie most block to the Buss
I'm thinking some block occupancy detection in the future for signals
Most will be tied to terminal strips in the event I need troubleshooting
I may try light bulbs for short detection
I'd rather have more feeders now than try to add them in the future
I will probably be the lone operator

Hi Gang:

Second try, it is in the files:

https://groups.yahoo.com/neo/groups/WiringForDCC/files

You need the full name to find it: "Final Layout for review".

Share your goals for your layout. The tracks run very close to the edges for any scenery.  The four parallel tracks look like they have a station between them. Are you interested in passenger service? Only a few sidings so perhaps not freight switching. Turntable and round house so the age of steam?

Do you plan to move the layout often? Can you work it from all sides? What space do you have available?

Electrically it is simple, plenty of blocks and only one reversing track, the green diagonal, if you don't count the turntable track.

Let us know. Carl

In response to my comment:

 

“  . . . keep those gaps inside the fouling point of your turnouts and equipment and it will reduce the number of problems due to shorts by reducing the possibility of shorts.”,

 

Bob inquired:

“Are you suggesting gaps closer to or farther from the frog?  Could you explain what you mean with a little more detail? Or point us to a diagram or discussion.>>

 

I’d be glad to, Bob.

The Fouling point is the location where equipment on the diverging tracks of a turnout would sideswipe each other.  Trains & equipment need to be spotted beyond the fouling point so equipment can move into/out of the adjacent track without sideswiping each other.

Starting from the point end of a turn out, you have points, frog, fouling point.  Your gaps go between the frog and the fouling point.  These gaps should be as close to the frog as is reasonably possible given the track construction methods used. 

The rationale is this – In theory, (most, there are always exceptions <>) operators will keep equipment beyond the fouling point so trains don’t snag on each other.  If they do that (as they should), and the gaps are between the frog and the fouling point, the metal wheels of stopped equipment are unlikely to span the gap, potentially creating a short if the turnout is thrown against the equipment spanning that gap.

 

We had an incident on a local layout where this actually occurred.  Track was hand laid, and one side of the frog extended about six inches down the yard track.  A train entered the track from the far end of the yard and pulled down to the far end, where it stopped with one of its front wheels spanning the frog gap.  As the engineer was moving slow, he was almost stopped when tht axle spanned that gap, and didn’t notice that he’d straddled the gap.  The turnout was against him, so the frog was one polarity and the rail under the train the opposite.   Additionally this was the last train of the session, so the short went completely un-noticed.  The layout was shut down and we went to beans.  Several work sessions passed where we had track power on for various reasons.  When we finally went to move the train for re-staging purposes, it wouldn’t move.  Inspection revealed that the gear on the front axle had gotten so hot that the plastic had flowed around the bearing block on that side of the axle, and had cooled around the bearing block effectively freezing the mechanism.  Layout owner, not realizing that any of this had happened, attempted to move the train by turning up speed on throttle.  Only thing that happened is track to decoder and decoder to motor wiring got hot and the insulation burned off.

All of this would have been avoided if the gaps had placed properly  (between the frog and the fouling point originally.

10 Amp Vs 5 Amp Vs 3 Amps for your layout.

Mark Cartwright
 

Hi all, 


I have more complicated questions... But first I believe we need to agree on some facts, which I am honestly hazy on.
===
First > Depending on your scale > Which amperage is needed and optimized?
Nearly guessing here...
3 amps for N Scale
5 amps for HO Scale
10 Amps for G....
? Or is this even applicable today.
===
Here is the other shoe to drop.... If I have a large layout of over 400 square feet of track stretched around a 21 x 60 foot rectangle. Would it be best to start off at 10 amps and hope the power gets all the way around or use small 3-5 amp boosters for a N Scale layout expecting to run upwards of 12 trains at a time.

Thank you for listening,
:)) Mark

===========
As for fire... I have personally witnessed 12 volt wiring on a 10 amp circuit basically burst into flame as it shorted near a gasoline line. Prior to 1973, it was not unusual to find Manufacturers running 12 volt wiring through the same chase as a gasoline line. A major difference between the 1972 vs the 1973 BMW 2002. Once, I learned this fact many years ago, I tended to be careful in choosing any car made prior to 1973, I wouldn't own a pre-1973 BMW and rewired a 1963 Panel Truck to the wiring diagram of a 1973 BMW 2002. There was also a practice in use  of the old days of varying wiring gauge, even in 110 volt circuits. Again a practice I tried to avoid and will replace a circuit with one type of gauge with fewer splices or connections. This maybe a factor more on a 10 amp circuit than a 3 amp circuit.

I also tend to separate wiring to type and other use. Such communication wiring being separated from power lighting. We have an additional consideration with DCC wiring.

The Construction methods of the day in the 1906 SF Earthquake place natural gas lines in the same pockets at the new to the day electrical wiring. It was fires and explosions which were the most fatal for San Francisco. Sort of like saying it was not the Hurricane but the flood which harmed New Orleans during Katrina then followed by lawlessness.

Wow!  Thanks for the explanation.  Sounds like the frog rails should be kept as short as possible.

Re: DCC Track Design for review

The outside tracks are intended for passenger service with a bypass for northbound and southbound trains where I have located the passenger platforms and station I preserved a lot of the buildings I had from 35 years ago and will be using them on the layout

The inner loop and sidings are for freight. point to point operation
I can run many different route throughout, twice around, point to point, reverse loop, etc

The era is not defined: combination steam diesel

The layout is a 5 x 8, I designed a custom table for my garage. I will share the plans and pictures with the group. The table sits on a sturdy base with locking casters so I have 360 access under the table is a display case for my rolling stock when not in use, and two 30" cabinets for storage. The top pivots and locks so I can roll it to the side when not in use. the whole thing will roll thru a standard 36" door and fit in a utility trailer for transport. 

Thanks for the comments on the wiring, confirming my wiring.
