I would not use wire that is smaller than 16ga for the track buss. 22ga is fine for feeders, but make sure that each section of track has a feeder.

Another good software option is XTrkCad, also free. Available on Sourceforge.net, and they also have a Yahoo group.

Johnny, most programs are written for Windows. If you are using a Mac, there is a good little program called Empire Express by Hayden Software that I use. Fairly cheap ( less than $50). I found it very useful.

I am a newbie to DCC and am trying to figure out the best way to wire. My HO

long. They go over and under each other so I've read that my track feeders
usually 22awg) would be fed by a block bus (say 18awg). The block bus then
feeds off the power bus (12-14awg) and this is where the detector sits. (Not

Re: Reverse Loop with Tortoise & Hare

Scott,

Thanks for the comments - I tried reversing the trigger inputs but no difference.

Perhaps my trigger sections are too short - about 1 inch. I also wondered if my loco's didn't draw enough current to trigger the Hare. (Blackstone C19's and K27's).

You are correct when you say the Hare instructions are awkward - I have read them perhaps twenty times.... They show three triggers whereas I have only used two - entry and exit. I couldn't actually see the purpose of the third trigger, but perhaps this is my problem?

I use this combination as well. IIRC, No programming is required to get the autothrow to work. Double check your wiring. You may have your two trigger rails reversed. The instructions that come with the Hare are a little awkward, but by reading them over you may find something you missed.

Hi Group, I'm new, but sure this has probably come up before.

I'm trying to automate a reverse loop with a T & H. I've wired 'trigger rails' prior to the entry and exit of the loop & programmed address 10 and CV 50 into the Hare and tried various combinations of values. I can trigger the Tortoise with the NCE Procab, so I know that part of the system's working. I suspect the problem will be somewhere in my programming. Can anyone give advice please?

Thanks

Johnny, I did a Google search with “model railroad track software” and came up with a number of hits.

Some are free, some are purchase.

 

The program I used was a freebee from Atlas called ‘Right Track’. It’s no longer available from their website.

I’ll send you a copy off-list.

 

Can’t give you any wiring tips without knowing the track plan.

Re: Wiring Setup

The previously mentioned CadRail works for this. While it won't read you plan, you can import it and trace over it. You can draw electrical circuits and wiring diagrams. Use it to layout a control panel, and print out a template to drill holes for switches and lights. It can print out a track plan for the track diagram on your panel. In short, anything you can draw on a drafting board you can draw in CadRail, and more. They have a trial version you can play with to see how it works. There is also a Yahoo group to help with the program.

Does anyone know of software that will help me design a control panel for my layout?  (It'd be extra nice if it could 'read' AnyRail plans)

They said it would detect a train in a train block. So since I'm only going to be running 2 to 3 trains at a time I'm thinking I wouldn't need this.
You have not clearly stated what your desired intention is for the use of occupancy detection. To address the question about detectors, one must take a step back and ask why you need any detector at all. Normally people add detection to the layout because they want to add signaling to the layout or some subset of that such as setting up some working crossing gate animation. To be clear, there is NO DCC requirement that says you must install signals or animation. These are all options you can add if you desire.

If YES you need a track occupancy detectors and the track elecrtrically broken down in to signal blocks. One detector per signal block and each signal block should be longer than the train. Even if you are not ready right now to install the signal system, planning the layout wiring to support it is a good thing to do BEFORE you build your layout. Otherwise there will be a big rewiring later. Beware the cost of installing a signaling system can cost as much as the what you spent on the layout before you added signals. Cost is the biggest reason why it is not done most of the time. Of the types of occupancy detectors the monitor track current, there are two types. Diode based and transformer/coil based. The NCE occupancy detector mentioned is transformer/coil based. Compared to the diode base detector, the list provided is correct in terms of the advantage over the diode type.

If NO, there is no need for any occupancy detectors at all and the question about detectors can be dropped.

How would a circuit breaker work in DCC? I'm very familiar with house wiring since my dad was an electrician.
DCC circuit breaker work just like they name but have some additional features. At a minimum, they detect current draw above a set level and trip as in enter the off state. To understand the need for them is to first understand the problem they fix.

Like a DC PowerPack/Throttle, DCC booster shuts down when there is a short on the track. This is because all DC Powerpack and DCC boosters all have a circuit breaker function built in and it self resets itself when the short is removed. The current trip point is the same the DC throttle or booster current rating. With DC, this was not a big problem because there was only one DC Powerpack per train. Only one train was effected. However, with DCC the single booster is running multiple trains and when the booster trips due to a short, all power is lost and ALL of the trains stop running. If there is only one operator, it not so bad. But if you have lots of operators, the other that did not cause the short will not be happy for they must wait on the operator with the shorted train to fix the problem. With a global short, the biggest advantage of running multiple trains with DCC becomes it biggest detractor when you have more than one layout operator and running multiple trains.

The 2nd issue that pops up with multiple train running is that during the fixing of the short, the short will come and go and OTHER running train will start and stop in a jerky fashion potentially creating more derailments. This generates even more displeasure.

Like a house with its multiple circuit breaker protecting certain equipment or areas of the house, a short at a given outlet will not cause the entire house to lose power because the main breaker tripped. Likewise if you device the layout into what is called in the DCC word "Power Districts" created by DCC circuit breakers, you can control how much of the layout is effected by a given short.

The DCC circuit breaker worked because it is designed to shutdown BEFORE the booster does. Most DCC circuit breakers have a Auto-Reset feature turned on by default. In this mode, the DCC circuit breaker return power to the track once the short is removed. The key point is that if you choose you power districts carefully, everyone else can still be running trains while you fixing your own short. Everyone is happy other than guy fixing the short.....which most likely he cause by himself running against a turnout....a self inflicted wound.

So the need for DCC circuit breaker depends if you have
1) more than one person running you layout
2) the layout designed to allow multiple trains to run safely unattended.

If the answer is yes to any of the two question, then you can benefit from the use of DCC circuit breakers.

Keep in mind that most DCC circuit breakers are designed to be used with 4 to 5Amp boosters which are normally found on large layouts.

You should also again plan you layout wiring to support Power districts which by the way are not necessarily the same as signal blocks but have almost the same impact on the wiring design.

Re: DCC locomotives won't run

Right and it says that in the Prodigy Express manual that you need the Advanced Throttle to read CV's.   I assume the person has the correct throttle when stating he cannot read CV's.   OTherwise there are a lot of bad rumors going around about the Express that are really operators errors.

Needing a programming track booster is a common problem that effects many DCC systems and not just MRC.

So at face value, again I cannot find anything specifically that says the Express should have more problem than any other Prodigy MRC system.
