How to wire a Shinohara DCC Friendly Double Slip into a layout.

cyrilatrockbottom <cyrilatrockbottom@...>
 

I cannot find any information from either any of the DCC forums/websites or the manufacturer on how to wire up the above-mentioned double slip ( Shinohara DCC friendly ). I don't know where to fit the insulated joiners, where to feed the DCC power, how to wire in the tortoise switch contacts. Thanks, Cyril....

Re: How to wire a Shinohara DCC Friendly Double Slip into a layout.

Cyril,

There is a wiring diagram for the double-slip turnout at
http://www.wiringfordcc.com/switches.htm. My experience with a the
similar Sinohara double cross-over, however, suggests that you give
serious consideration to powering the frogs, and especially so if you
are running any steam locomotives. Using Tortoise switch machines, you
can do this as follows:

(a) Connect a wire from the Tortoise's pin 4 to the frog

(b) Connect a wire from the Tortoise's pin 3 to one rail

(c) Connect a wire from the Tortoise's pin 2 to the opposite rail

You may need to reverse the rail connections to achieve proper polarity,
however, depending on the way you have oriented the switch machine. In
addition, of course, you will need to run leads from your double/single
pole switch to the appropriate pins on the Tortoise.

DCC wiring my layout... question

jrsmos <jrsmos@...>
 

Hey,

My HO layout is a 16ft x 32ft around the room layout with two levels basically both levels all the way around the room joined by helixes. I will be using NCE PH Pro 5A system. All switches (84 of them) will be tortoise machine controlled and run by NCE SW8's and mini panels on a separate booster accessory bus.
My main bus run (12 ga) and the accessory bus run (14 ga) end up being approx. 45ft long in each direction from the command station to cover each level. Is this too long even if I use 'snubbers' at the bus ends?

Connecting Different DCC Systems

bmrailroad <bmrailroad@...>
 

I am a relative newbie to model railroading and have been researching how to build my modular layout. My predicament is that I have several local modular railroad clubs nearby who use different DCC Systems. One uses Digitrax, another uses Lenz, and the other uses NCE. I own the Digitrax Zephyr and plan on using it to control my layout. It uses 6 pin phone jacks. However, to make my modules usable with two of the three other DCC systems I will need Cat 5e plugs. Is it possible to wire a module with two different sets of bus wire and jacks on the fascia to allow for use with all of the local clubs? Home Depot sells a small face plate with two empty slots which would allow me to insert one Cat 5e and one 6 pin phone jack into the holes.

Thanks in advance for the help.

Re: Connecting Different DCC Systems

That should work. Just label them and realize the 6 pin plug may fit into both of your jacks. So labeling is important.

Re: Connecting Different DCC Systems

Vollrath, Don <dvollrath@...>
 

Of course. Anything is possible. You can include separate control/cab bus runs and connections under each module that are compatible with several brands of DCC systems. Just provide the connector(s) as required for each hand-held cab for each brand....And label them as to which plug should be used for which DCC brand. One of the challenges however will be to agree on how the various control buses connect from module to module. You will need to comply with whatever the modular folks have set as the standard for say, Lens, NCE, Digitraxx and other control networks. Obviously, only one network type/brand will be used at a time. But you may be creating more risk and controversy while trying to save a few wires. A more fool proof method would be to simply wire up each network type separately from the others. You can still provide the cab plug-in sockets at a combined compact location. Simply cover up the unused cab plugs at each show venue to limit operator confusion.

Re: DCC wiring my layout... question

Vollrath, Don <dvollrath@...>
 

Nope. Sounds like a good plan. Add a R/C filter/terminator/snubber at the far end of each DCC bus run...Track and accessory. Unless you plan to have more than two operators, there should be no need for multiple boosters or to split up the track bus into multiple power districts unless it simply to have a separate track bus run for upper and lower levels for wiring convenience. However, using a separate booster for accessories is a good idea. An alternate would be to use en electronic circuit breaker to separate the track bus from the accessory bus.

Modular DCC Wiring

bmrailroad <bmrailroad@...>
 

I am a relative newbie to model railroading and am in the process of designing and building my first model railroad layout. I decided to make it a modular layout due to space requirements and the desire to bring it to local train shows on my own and with local model railroad clubs. I have purchased a Digitrax Zephyr to control my layout. On my modules I will use RJ12 (6 pin phone/data) jacks to connect the DCC bus wire. In my area there are several model railroad clubs with which I would like to participate. Each uses a different DCC system including Digitrax, Lenz, and NCE. As I understand it, Lenz and NCE use an RJ45 (Cat 5e) connector and wire for their DCC bus.

I understand you can not use both systems at the same time. However, is it possible to have two different bus wires and jacks on a single module, so that it can be used with either clubs layout using different DCC systems?

Home Depot sells an outlet cover with holes for two jacks. The face plate allows you to clip in whichever port you need. If it is possible to wire a module for both DCC systems, I would put a RJ12 in one and an RJ45 in the other.

Let me know your thoughts on this idea. I am very excited to get started with construction of my modules, and welcome any recomendations from fellow model railroaders.

Thanks,

*SUGGESTION #2-10: Use of Double-Slip Turnouts.*

It is a darn complicated thing! At least on one manufacturer, several
of the little rail pieces are not powered. Read below how to fix that.
If you do not, it is no wonder engines frequently stop on them.
Typically, a double-slip is used where very tight switching is
required. This means small engines and going slow - no chance to coast
through. If you are using an 0-4-0T, you are definitely going to have
problems.

Most modelers and clubs will not allow the use of double-slip turnouts;
probably mostly because of the problems just mentioned. I cannot attest
to whether there are mechanical issues as well since I have heeded the
warnings of others and will not use them myself.

Assuming you need to use them, Bob Clegg, BobcatCS@...
<mailto:BobcatCS@...> has been nice enough to solve the problem
of powering them and provide a picture to guide you on doing the same to
a Shinohara double-slip. He came up with a pretty simple solution that
will power most of the rails.

As you can see, his approach is pretty simple. He writes, "Note that the
frog rails of these turnouts are insulated from each other so no
insulated rail joiner is needed. If shorts on the frog rail occur, they
can be cut and epoxied just beyond the frog. This will limit the dead
area to about and an inch and a half [37mm] and will not be a problem
for any but the shortest wheel based locomotives." {Murphy says: OR the
locomotive YOU are trying to run!} Seriously, Bob mentions that you do
make sure you have a locomotive that has good power pickup on at least
two axles on each side that are more than the 1.5 inches apart.

He mentions that his polarity is the same on all tracks. That means do
not try to run a reverse loop /through/ the double-slip. */Be
creative!/* You can still use this on a reverse loop if you need to. For
example, the balloon track itself can be the reverse loop keeping the
polarity on this turnout the same on all four tracks. There are probably
lots of ways to have this turnout on a reverse section. Just make sure
that your shortest reverse section is at least as long as your longest
train. Just in case you /really/ want run a reverse section /through/
the turnout, that may not be a great idea. I've seen one way this can be
done. It is /very/ complex!

A few notes:
1. This is not DCC friendly. Some turnouts this is hard to do to. This
is one of them. I suggest you put a light bulb or an electronic circuit
breaker in series with this turnout if you need to use it.
2. It would also be difficult to run wiring to the points. This may
eventually be a point of failure. If you are very good at soldering, you
might be able to wire power to the points. Otherwise, avoid short wheel
bases.

Denny Anspach <danspach@...>
 

Most modelers and clubs will not allow the use of double-slip
turnouts; probably mostly because of the problems just mentioned.
Heeding this misguided advice denies for the same layout modelers and
clubs the operational, spatial, prototypical and visual advantages
that these elegant turnouts can and do bestow. I have five Shinohara
#6 code 70s and one Railway-Engineering #8 code 83 double slip
turnouts in daily routine DCC operations on my DCC layout, and they
richly contribute the advantages just enumerated, not the least
freeing up considerable valuable space.

They are not without their problems, the principal one being the
intolerance of the low angle crossing frog inherent with these types
of turnouts to wheel sets that are out of gauge, have incorrect back-
to-back measurements, or truck wheel sets that are out of tram, or are
not in a linear line-up. Rather than punish the turnouts for these
problems, this problem has been a powerful goad to do what the modeler
should be doing anyway: the ensurance of the highest quality
trucks, wheel sets, and trackwork. On one Shinohara double slip, it
has been useful to cement in place some small additional guard rails-
a very minor job.

The bulk of my motive power is brass steam, and all that has been
converted to DCC also has had additional wiper pickups installed on
locomoitve and tender to pick up current from both rails. This
eliminates the potential problems of the short dead sections.

Wiring these turnouts is pretty simple: all rails north of the
imaginary longitudinal center line should be jumpered together; and
all rails south of the centerline ditto. Shinohara double slips from
the past ten years of so come already so internally wired/jumpered. I
have several older turnouts where such jumpers cannot be taken for
granted, and I have had to personally add these jumpers myself. One
feed to the north rail and one to the south: that is all that is needed.

The primary frogs are already isolated, but the respective north/
north and south/south frog rail pairs need to be respectively jumpered
(by the modeler!).

Interestingly, when these double slip turnouts were first imported by
Lambert in the '70s, the Model Railroader had an article in its TRACK
TOPICS pointing out the simplicity of wiring these turnouts. The
introduction of DCC has not changed that, and the best wiring is
exactly the same.

Re: How to wire a Shinohara DCC Friendly Double Slip into a layout.

Bill Wilken
 

Well said.

While I have no experience with Shinohara's double-slip turnout, I have
experimented considerably with its double-crossover. Based on this
experience, I am somewhat skeptical of how the double-slip turnout is
likely to handle steam locomotives with 4-8-4 and longer wheelbases.
While I have not encountered any mechanical or electrical problems as
such, it is hard to characterize passage of my BlueLine 4-8-4 through
the #6 turnouts of the crossover as especially realistic or graceful.
There is simply too much lateral bumping even when all wheels are "in spec."

Digital control for Marklin and Roco

Pure newbie question about dcc.

Can both Marklin 3 rail and Roco 2 rail motors be run at the same time on the same track system by use of any dcc control system?

Re: Digital control for Marklin and Roco

Probably not. Never seen either one, but I would expect the 3-rail system to have non-insulated wheelsets, which would short out the 2-rail electrical system.

It's been more years than I care to remember, but IIRC, Marklin track does not insulate the two running rails. If they were, there would be reverse loop and catenary power configuration issues (which rail is the return?)
