Re: Preventing a Short at Turnout

Thanks, Glenn, this is the answer I am looking for, but I am a bit fuzzy on
how/where to hook up the SPDT switch (and the type switch)? I am using
Tortoise machines on Dc circuits ( the train control is MRC DCC).

I used this trick on my old DC layout.

RicZ

A long section of track isolated would be dead when incorrectly set for the diverging route if turnout is set for straight run. When set for the diverging route would be powered. I believe frog controls have a set of auxiliary contacts that could be used. One contact and common for power and the other contact not use. Need to draw this ou
t on paper.

a double pole double throw contact, switch, relay or other would work with one of each rail dead, diverging route or straight route.


Re: Hidden Reverse Loop

bydabayou <bydabayou@...>
 

Eric,

Does it matter to you which direction the train takes through the hidden loop? If it does need to always go clockwise (or counterclockwise), that complicates this a bit.

1. If not, try the PSX-AR, as other have already suggested. This is the simplest way to do it. Each time the train enters the train enters the loop, it will run into the track the last train exited. All will stay as it was until the train reaches the gaps at the opposite end. When the PSX-AR senses the engine at the gaps, it will reverse the track power phase and toggle the turnout to allow the train to leave. Distance from the turnout to the gaps is determined by train speed, so the turnout can move before the loco arrives at the points.

2. If the train must always traverse the loop in the same direction, the suggestions you have already received to use a PSX-AR are still sound. You will simply need to find a way to throw the reverser back after the train leaves. The PSX-AR instructions show how to wire a pushbutton using a wire connected to the rails across a gap to do this. You can replace the pushbutton with any relay or other controlled contact. on a timer triggered by the reverser if you get the PSX-ARFB (feedback) version, etc.

Bus slang for bus bar. Bus bar-heavy copper bars capable of carrying a lot of amps. Residential 200 amps, industrial 3-4000 amps. All depends on physical size and dimensions.

A bus is a conveyance; something that carries stuff. A Greyhound bus
carries people. An electrical bus carries electrons.

Years ago there was a company named Buss that made cartridge fuses.

I think a lot of us have confused the two in referring to the pair of
primary DCC conductors. The only "buss" in electricity is that historic
fuse.

Yup.

Use an old analog trick and extend the frog rails back at least the length
of your longest locomotive (+tender) wheel base. You may want to go longer
just so the engine is in the clear.

For DCC wire these rails through contacts so they receive no power when set
against the route of travel. Do not wire them to the frog wiring.

For DCC simple SPDT contacts would work. The center contact is wired to the
Buss, the other contacts are wired to the rails so they only receive power
when properly aligned.

Re: Hidden Reverse Loop

Vollrath, Don <dvollrath@...>
 

Look at the PSX-AR. Or look here http://www.wiringfordcc.com/sw_ctl.htm#a16 as this will work with any A-R unit. Just set up the rail gaps far enough back from the exiting turnout so that it will complete the throw before the train arrives. Many other practical combinations exist... especially if there is or will be an electronic control operating the turnout motor.

Re: Preventing a Short at Turnout

Vollrath, Don <dvollrath@...>
 

Is there a SIMPLE/CHEAP way to prevent a train from going through a closed turnout and causing a short? Of course... Just shoot the engineer! Or at least take away his DCC throttle. ^_^
Really, the answer comes by answering many other questions. How is the turnout controlled... manual, twin coil, or tortoise machine? Do you have some kind of electronic unit controlling it? Is there a way now to sense the position of the throwbar? Do you want the train to stop or the turnout to auto-throw? Is there a reversing track involved? How fast will your trains be approaching the turnout? In other words...How far back do need to sense there is about to be a problem? If you want the train to stop, what is the minimum distance of 'dead track' that is needed? How idiot proof does it need to be? How many $$ is too many?

Here are a couple of ideas. 1) See http://www.wiringfordcc.com/sw_ctl.htm#a16. This gets a simple Tortoise machine to auto-throw by adding a small relay to an existing A-R unit. 2) If there is a manual turnout control with a frog switch like one shown in one of the recent MRR publications, or a Tortoise machine you can use the throwbar position electrical switch to un-power a section of rail leading up to a turnout thrown the wrong way. 3) The Tortoise and Hare controller combination can be added to yield auto-throw. 3) Many other turnout machine controllers can be triggered to auto-throw by use of remote light/shadow or IR train sensor.

Let us know more about your situation and 'druthers' so we can provide more pointed answers.

I've got to agree with Max on this. If you are running turnout, you are not
paying the attention to your train you need to.

It is the engineer's job to watch the track in front of him and take the
appropriate action.

Re: Hidden Reverse Loop

wirefordcc <wire4dcc@...>
 

Ric,

Check out the Hare by DCC Specialties. I have a brief description on my website at:

http://www.wiringfordcc.com/sw_ctl.htm#a17

It uses a sensing section to throw the turnout ahead of the train. I'm not sure if the sensing section will work with a reversing loop. Ask when you contact DCC Specialties. While it doesn't reverse a loop, it can power route the frog for you.

If the sensing section does not work with a reversing controller such as the PSX-AR, I think the Hare will still work for you. The Hare has inputs for switches. You should be able to use two IR sensors as the switches. Don Vollrath, who monitors this forum, should be able to fix you up with some IR sensors. Just mount the sensors below the rail head.

Re: Guru wiring help - REVISITED

Richard,

Do you have access all around your layout? Or are you dealing with any walls around the outer limits of your table? The reach to the corners of your layout will be quite far from the center.
I agree that the height of the layout should be considered carefully. That is one of the largest concerns with my current layout. I made it too low. If I were to do it again, I would make it at least 46" at the lowest points.

You could call Team Digital in Kokomo, IN. Bill Robinson has always been
very helpful to me. I have two SMD82s and use them in conjunction with my

and follow them, and you should be successful.
