The recent MR does a great job of charting out the different characteristics of various DCC systems. One field in the chart is labeled “route control.” However, I can’t seem to find the section of the article that discusses this. Can anyone explain what “route control” is? Is that the ability to control turnouts via DCC on your layout?
The “Hare” (companion to the “Tortoise” switch machines by Circuitron) is also described in MR. The Hare advertises route control as a feature, but I have no direct experience with them. Since Circuitron offers signals and other electronics it is worth investigating. I wonder if a computer is involved or if the control logic is all distributed via DCC and Hares…
I had the VERY same question that you had, Jeff. That’s what bugged me about the article. It was a good, general report about DCC but left items unaddressed. A list of term definitions for their comparison chart would have been very helpful. Consumer Report usually does a nice job of that on their comparison charts and explains what each term means. (We’re not all at the same level.)
I would have also enjoyed a couple of brief paragraphs on each of the systems that mentioned things unique to each one of them. Does “route control” refer to the ability to hook up a computer to a RG-232 port to run your turnouts or signalling system? It wasn’t very clear to me either…[:(]

If you use stationary decoders to power a bunch of switches, it’s real simple to set up macros to line each route.
It’s funny no one has even attempted to answer your question, so I will try. I’m no expert with DCC, but do have some experience, as I am using DCC to control my layout. Yes, route control (also called map routing) is the ability to control your layout with computer programming. It may be accomplished in other ways for DC, but since you asked about DCC, we’ll stick to that. Map routing includes the ability to control turnouts, signals and other items, (such as reversing units) through computer programs. Basically, in an ideal world of map routing, one would be able to just sit back and watch trains run a pre programmed route. Somewhat boring to some, but it does have it’s advantages. And it’s kinda cool, too. I hope my ameature explanation is enough.
Thanks, On30Shay! [:)] That clears things up - at least for me. Maybe MR should of had you contribute to the article. Then we wouldn’t have needed the clarification in the first place.
Tom
you throw many turnouts, or any stationary decoder equiped devices, with one command
don’t need a computer, you initiate the macro from your throttle “macro” button (NCE, anyway), you program what you want the macro to do through your DCC system
a route may be … aligning a bunch of turnouts to get an engine through a yard and into the engine house, etc

A simple route control involves switches only. A complete route control tries to mimic a real world scenario, as if an engineer would sit in each of your locomotives with CTC setting the switches and sending speed limits or stop commands via signals which your engineer would obey.
Both kinds of route control are used in ZIMO systems for decades, mostly in conjunction with a computer and STP software. ZIMO#8217;s route control goes beyond simple switch ladders or macros, as some call it and is therefore ideal for automation. This can of course involve things like hidden stations or a complete layout. The computer sets routes on its own, with previous checks to ensure a route is free (unoccupied) and no switch, signal etc. is reserved or locked by another route, then sets all switches, signals to their appropriate settings and finally issues speed limits to applicable sections of track. This is called #8220;signal controlled speed influence#8221; in ZIMO language, and is capable of issuing up to 5 different speed limits to each section, including stop and #8220;power off#8221;. The speed of each loco (or consist) for each speed limit may be individually different and is set in 5 decoder CV#8217;s.
This does not lock anyone out of manual train control. Any combination between manual, semi-automatic or full automation may be applied simultaneously. By hitting a #8220;MAN#8221; key on a ZIMO cab, the operator can take any locomotive out of automatic operation, at any time, without consulting the PC first! In essence, the loco address you use the #8220;MAN#8221; k
Does anyone know where all does funny numbers came from after hitting the “Post New Reply” key?

Art,
Since you are on the line, I have a question for you. Why is the Zimo DCC system substantually more expensive than all the other DCC systems? The two mentioned in the MR article were ~$950 and ~$1,250, respectively.
To put it another way: What is the extra few hundred dollars getting me that the other DCC systems don’t have? Or, why should I spend the money on a “Lexus” when a “Camry” will do just fine? Thanks!

I think Al left the building…
I started to read through this thread, but got bogged down in all the non-answers and partial answers so I don’t know if anyone ever said what route control is, or not. Just in case they haven’t, here it is:
Route control is basically using a single command to set the alignment of one or more turnouts as necessary to get your train to where you want it to go.
Depending on which DCC equipment you use, and whether you use layout control software, that “single command” may be implemented in the DCC command station, your stationary decoders, an accessory device such as Team Digital’s SRC8, or the computer software.
Different manufacturers use different terminology to describe the various route features and implementations they support, so it may take some reading up to compare one against the other.
HTH,

Tom.
If you read through my previous post, you#8217;ve seen a number of features no one else offers. Further if you study the ZIMO literature including (maybe especially the manuals) you#8217;ll find many things that set ZIMO apart, starting with seemingly little but important things like digital volt and amp meters for each track output, fully stabilized track voltage, fastest CAN bus (communications bus) all the way to user updatable command stations, cabs and decoders via Internet, no charge, without lifting a cover or removing a decoder.
Take #8220;signal controlled speed influence#8221; I mentioned in the previous post. When compared to other methods of stopping trains in front of a red signal, like brake generators, DC and asymmetrical signal stop, ZIMO offers the most advantages:
- full control of all loco functions in stop or limited speed sections
- speed limits can be individually overridden with the #8220;MAN#8221; key at the cab
- 5 speed limits for brake or low speed sections, including stop and
selectively turns power off in blocks (for hidden stations to save power
and extend bulb life) - special ZIMO decoder CV#8217;s for individual speed limit settings and
additional momentum when operating under signal controlled speed
influence. - only one rail needs to be gapped for blocks, no short circuits when
bridged by wheel set
Art,
Thanks. No, I didn’t take your posts as a put down to other systems. This is the sort of thing that I wi***he MR “DCC Buyers Guide” article would have elaborated a little more on. Thanks again.
Tom
BTW, Art - I think you have a macro linked/associated to your apostrophe or something. (It’s not consistent though) Anyhow, I think that’s why you are getting all those numbers scattered about your post.
Route control is the ability to throw one or more turnouts from your cab.
I’m using routes with my Prodigy Advance and Team Digital SMD8 stationary decoder. The decoder can control up to eight turnouts (more if some are wired in parallel). All programming is via CV’s from the cab. Operation is: Press Route button; Press route number; Press 1 or 2 for closed or thrown turnout; Press Enter.

Thanks Tom.
I feel the same way about DCC articles. They seem to lack in-depth information and usually only cover features as far as they are compatible between systems. Otherwise, there should have been an article a long time ago in magazines like the MR dealing specifically with the items we’re discussing, especially considering that ZIMO’s route control in the form of “signal controlled speed influence” is around since 1980 and ZIMO’s loco number identification and location" since 1989!

The definition of route control in terms of controlling turnouts is: A system that allows for one or more turnouts to be controlled such that a route is formed between two points.
The application where route control becomes very useful is complex track segments. In high volume traffic situations it becomes critical that a large yard has many ways trains can enter, exit and otherwise move simultaneously. If you have 20+ turnouts in a complex throat and use a toggle or buttons for each then you end up with a very messy and hard operation. To line up a route in such a situation you must look at each turnout between two points and determine its needed position and switch it correctly. This process can be a real pain in operation where many routes are needed quickly to move traffic.
Route control helps because it does all the switching automatically and simultaneously. The only input is to tell the system which route you want. The interface of route control varies greatly.
Diode matrix route control is one of the first forms. There are routes formed with diodes. The diode’s role is to give power to the switch motors in such a way to line up the route. There are problems with the system that have to be overcome in designing the circuit. It’s easy to use once designed, but it’s a stumble block to get it to work in various setups such as with the tortoise.
DCC systems usually operate route control through stationary decoders. The cabs that are used to operate the trains can also operate the decoders. If route control is supported then you can designate routes. When you select a route from the cab then the command station will send a signal to the stationary decoders to tell them what position they need to be in. The turnouts align accordingly. The problem is the cost of the stationary decoders is very high and operation using the cab to get routes is clumsy and inefficient.
Discrete logic gates or relays can be used. Logic gates include TTL and CMOS bin
I DIDNT UNDERSTAND THAT EITHER
Like I said, I’m no DCC expert, but I knew when I answered, there would be a dam burst of answers to get more “coerrect” or technical. Which is great. At least now, you have a plethora of answers to choose from. Before, you had none.
Lastly, I suggest you go here: http://www.freiwald.com/ Read ALL of it. You can see for yourself what route mapping is, and how to use it. Don’t rely half answers, like someone said earlier. That site is the cutting edge in computer programming for DCC. No one else even comes close. Don’t let anyone tell you they do. Read for yourself, you’ll see. I thought about map routing with a computer, but the era I’m modeling really requires me to use ground throws to be prototypical, and, somehow, I have gotten REALLY hung up on being prototypical. It’s a lot of reading, but well worth it. By the way, like someone else said, you CAN do map routing without a computer, but throwing the computer in the mix makes things MUCH easier. As cheap as a simple computer would be, if you’re going to use map routing, there’s no reason to do it without one.
