There is also a 3 way turnout in Peco code 75 electrofrog style.  However, unlike the code 100 ones it is an asymmetric design.  Therefore they can be wired just like one would do for 2 turnouts connected together and it does not require care in order of changing point positions since the points do not overlap.

Spoiler alert:  This turnout appears to be only offered in code 100.

Re: Peco SL-99 3 Way Turnout

Dennis DeGroff
 

Hey Nick.  Thanks for the response.  My units are not in a reversing loop, as they just butt up to each other in the yard.  Since I have not added ballast yet, I am going to pull up the track and turnouts so that I can add the insulated rail joiners as Peco recommends.  Hopefully that will take care of the issue.

Best Regards, Dennis.

Re: Peco SL-99 3 Way Turnout

Nick Ostrosky
 

I have two of these as well but not in a reversing loop.  You are correct that Peco recommends insulating the four inside legs, which I did, and have experienced no problems in operation.  I would think this would hold true regardless of the reversing section because of left/right rail issues and how Peco recommends wiring the turnout to power those rails.  As to simply cutting gaps, yes, you could, but that could invite arcing, alignment, or other issues that may be less than optimal.  Nick your nearby neighbor in Kalamazoo, MI

Peco SL-99 3 Way Turnout

Dennis DeGroff
 

Hey everyone.  New to the group and wiring my first layout in DCC.  In my yard district, I have wired two Peco SL-99 3 way turnouts with the toe end opposite each other and joining from the right side of one to the right side of the other.  I installed the units with conductive rail joiners on each of the three legs exiting both units and soldered the joiners only on the toe end of the turnouts.  I have been having a problem with a locomotive shorting out (using PM42 Digitrax for power management) when going from one SL-99 to the other SL-99, but no problems going to either of the other two legs of the turnout.  Both the turnouts are on the same power district.  In reviewing the Peco information on the SL-99 packaging, I noticed that for DCC operations, they suggest placing insulated rail joiners on the inside 4 legs.  Could this be part of my problem?  If so, can I cut an gap between the sections to basically isolate the tracks without the need for the insulated joiners?  I have checked the wiring below the layout and also with the 9v buzzer check when the wiring is disconnected from the PM42 and all checks out good.  The loco is a Walthers Proto 2000.  Any suggestions would be greatly appreciated.  Dennis DeGroff, Fort Wayne, IN

Re: Reverse Loop Question

Don Vollrath
 

If your photo is accurate, there are 3 relatively independent reversing loops. The Red outside loop and each of the 2 Green indicated loops. AND a possible wye toward the center (the track sketch paths are not perfectly clear.) The yellow marking for planned track gaps would end up with the green reversing loops coupled inside the red loop. I would move the gaps for the Red outside loop to be so that only that track loop is isolated. Then place other gaps to isolate each of the other green loops from each other where they break apart from the turnout exits. This move would best utilize 3  independent A-R units, each powered directly from the mainline feeder bus. 2 separate (green) loops may not be necessary depending on the actual length and planned movement restriction of trains on those staging tracks. 
In this manner you can add independent track occupancy detection on leads to these 3 areas after each of the A-R units if desired.

The wye in the center also needs to be carefully looked at for reversing issues. It creates a very short reversing area where a loco or train can enter from the main line, go through the wye and return to the mainline in the opposite direction. ie - a 4th reversing loop independent of all others. This in itself may require yet another A-R unit with track gaps placed to prevent one A-R area from being adjacent to another. Knowing or restricting train length through this path will be paramount for success 

Can you quantify any restricted movements for future trains at this end of the layout?

Reverse Loop Question

Wayne Swearingen
 

Looking at the photo's there should almost be a groups page dedicated to reverse loops! 

We're in the process of converting to DCC and in deliberations on how best to wire/block the loops we have. There is only one mainline running around the loop but there are staging tracks off of it. I was planning to detect occupancy on the mainline but not the staging. If we do detect staging the BDL168 will work with one zone-section setup for auto reverse, I'll have three sets of tracks to detect and the fourth can just die or possibly be used elsewhere within the loop if need be, may splitting the mainline into two detected zones. If we just do the mainline I'll need to purchase a BXPA1 unit to detect it as one. 

What do the experts here say as far as gapping & setting up the reverse loop?

Re: Older Shinohara Turnouts

Brian Eiland
 

Hi George Galyon,
You seem to be a rather expert on these Shinohara crossovers, so I thought I would double check with you.

I have 2 older style DOUBLE crossovers, and 4 older style SINGLE crossovers,....all of them have the 'double crossbar features'.

I had sought to utilize one of the DOUBLES at a particular spot on my layout,...and I had read your excellent PDF on Allan's DCC site about making this turnout work in DCC mode WITHOUT significant modifications.

I have now found that I have room to install 2 in-line SINGLE crossovers instead of the DOUBLE. I believe it would be safer/less troublesome down the road if I utilized this 'singles' configuration rather than the 'double'?

Are there modifications needed on these singles to use in DCC?...or modifications that might be recommended??

I checked with my meter fifteen years ago. I check periodically. I worked for NASA for fourteen years at Wallops Flight Faciliy. I kknow the details.
Good enough for me.

Hi!
This may fit the bill.
It works with several manufacturers Command Stations.

Theorectically you should be able to because all up to date manufacturers use national standards.

No one is following the DCC standards in US.  No one has changed the design of their boosters since they were designed and release well before  the standard came out a long time later.


However if the boosters you're using have any age and considering how tempimental DCC is, I would recommend single source manufacturer for a new layout. Think about it, if you tracking down a problem you're not going to know if it's a short or a manufacturer conflict. I like to say "never enough time (or money) to do it right always enough time to do it over".

Then it is not.  ESD safe units are identified with the ESD safe symbols.  Older units have the three prong plug, and they are not ESD safe.

Re: Current through the soldering iron tip

Don Vollrath
 

ESD Safe is not the exactly the same as current leakage or as simply grounding the tip of a soldering iron. There is as special spec and requirements for it to protect sensitive electronic equipment.... like microprocessors and amplifiers used inside decoders. Remember seeing sparks from your fingers when handling wool sweaters in dry humidity conditions?  See https://en.wikipedia.org/wiki/Electrostatic_discharge.
BTW - When you use a grounded soldering iron make sure that whatever thing you are soldering to is NOT energized. Otherwise you are creating a direct path for current to flow from whatever source it is connected to by touching it with a grounded soldering iron.

Then don't do decoder or electronic work with it. I wouldn't risk smoking a decoder with a non-ESD safe iron.
