What are Reverse Loops?A reverse loop, sometimes called a balloon track because of its shape, allows a train to change direction without going in reverse.
Wiring a reversing section, including loops like the one shown here, wyes and turntables is as easy as cutting gaps in the rails and inserting a DPDT Toggle switch wired as shown. If your model railroad uses a conventional DC (Direct Current) power supply, adding a reverse loop is only a toggle switch away. Isolating the Reversing SectionBefore you can wire the reverse loop, it must be electrically isolated from the rest of the railroad. Before the train can enter the loop, the toggle switch must be properly lined so that the polarity of the reverse section matches the polarity of the rest of the railroad at the entrance point. If you only use the reverse section in one direction, plan ahead and reset both switches when your train has completed its run through the track. Like conventional DC wiring, the reversing loop or track section must be electrically isolated from the rest of the railroad even with Digital Command Control (DCC).
Not to high jack the thread, but you know stein, the more I see this plan the more I like it. Basically use the mainline, and your yard track that already exist and add the 3rd leg of the wye. Ok, I have been trying to take the layout that Stein posted and recreate it in SCARM, but I am not having much luck.
I have tried several of the free programs out there and I can't figure out any of them very well.
Some swear by SCARM, which is a new program by a Bulgarian guy who popped up on the net maybe a year or so ago, and apparently is trawling quite a few model railroad groups to tell them about his program. Structural design is about placing the main elements into a room - yards, towns etc, and how they will be connected. The detailed design - the exact location of tracks, turnouts etc in each scene is the last level of design. Most people have a tendency to skip the first and second phase, and then start churning out plan after plan after plan in the third phase, still not clear about what they are trying to model. I could zip up that file and upload it, but it would be useless to you - wrong scale (H0 instead of N), wrong theme (urban switching layout). I would recommend not spending a lot of time now on drawing detailed designs, and instead spending some more time on figuring out the overall idea.
Do you primarily want to stand before a scene and watch trains pass through the scene (the railfan perspective)?
For a yard - are you fascinated by sorting arriving cars into outbound blocks, to build new trains and send the blocks out on new trains? Are you fascinated by passenger car service - like handling head end traffic (express freight or mail), or taking off or adding a sleeper or a restaurant car for the next segment of the trip? Or is it the engines that you are fascinated by -do you want to have an engine terminal with a diesel fueling pad and sand refilling, a diesel house or something like that? Or is a yard to you just a collection of parallel tracks where you can hold whole trains before they go on a round around the layout - i.e. Browngd: using your room photo, it looks like you are going to use a duckunder or liftout at the door. Stein, I have an understanding of what I want to do, I guess I just haven't done well at communicating this. This accomplishes two things, it allows me to have the interest of switching operations while allowing for me to just run continuous for the kids who are too young to understand switching at the moment. The concept of having a yard off a wye is that you can arrive in either direction on the main and head into the yard, and you can head out of the yard in either direction. I think the other point Rex was making was that by having the peninsula come off the right or the left side of the room, or down from the top (instead of up from the bottom by the door), you have more room for a wye. And of course - there is nothing that says that the main yard will have to be on the peninsula - you might as well have a spur down to some industry on a peninsula, and have a double ended yard that also doubles as staging for a couple of trains e.g.
Thanks Stein for following up on my post and giving a much better description of what I was trying to suggest . Now, the reason for all of that is because this presets exciting opportunities for my layout. A 180 degree turnback loop (I prefer the word curve here) is often called a return loop (Like a half circle).


Yes I am just looking for ideas and schematics simply for the construction of a loop that would start at and return to a wye in the middle of it with the purpose of letting my trains make a complete run on my point to point layout.
The CL2N3-G picture compares the size to a resistor, and the TO-92 picture shows the module with its 3 legs. The leg marked NC (Not Connected), can be cut off flush with the body, as it is not needed.
The FR_Circuit picture shows a simple circuit for wiring a forward & reverse LED for an Analogue setup.
A search on the web will also provide many more applications for this wonderful little device, and there is another version that can supply 25mA to a LED, a CL25N3-G IC. Jim told me to get some elmers glue and put a small drop on the cars and also on the wood packs.
In an enclosed space it’s probably only safe to have no more than ~15V across the device.
I think you mean rubber cement not elmers gloe, and yes it works great for everything from keeping loads of flat cars to holding down your track planning templates. Since I always have trouble remembering what I got from folks like All Electronics, Mouser, etc, and it got too crummy today on the course to play the 2nd nine, I thought I'd provide some details on parts I used. Oh, the yellow LEDs are power indicators for my three subdistricts, outputs from my OnGuard circuit breaker boards, so they are on when ok and flash when shorting. From that single wire you can enervate your panel lights and any and all signal masts you wish to install out on the layout.
Levers for signals are at the ends of the row and are painted red, levers for switch points are painted black. The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961. I use the same schematic for my turnout indicators, but mine are at the turnout as shown in the photos. Trains complete and end their runs in this yard and are already turned for their next departure upon arrival.
Trolleys frequently use reverse loops at the ends of runs, taking advantage of their tighter turn radius.On a model railroad, as with the prototype, reverse loops consume a lot of space, but are the fastest way to turn an entire train. This method will work with the control systems offered in most two-rail track train sets on the market today. This can be done by inserting insulated rail joiners on each rail at each end of the reversing section. This can be done with plastic rail joiners or simply by cutting gaps in both rails at each end of the reverse track.Reverse sections can still have their polarity flipped manually with a toggle switch with DCC. These circuit boards detect the short circuit when a train enters or leaves a reversing section lined against it. Hard to learn, easy to use once you understand how to think (draw straight track, use curve tool to connect, parallel tool to do parallell tracks, difference between right-mouse-down-and-draw and left-mouse-down-and-draw, shift-click to change which endpoint of turnout is the active one and so on and so forth).
Not really all that important which program you use - the important part of design is done with a napkin and a pencil - the high level conceptual design - figuring out what you want to do. Do you want to walk along with the train to pick up and drop of cars (the train crew perspective)? I am retired from a power utility and use the info I have to include running electric (not hot) to all of the locations that us electric. For the wire on the power poles and high tension towers I use the elastic thread sold at sewing supply stores. As a note, the toggles in your switch tower should all be DOWN when the points (or signals) are lined in their NORMAL position and should be UP to reverse the switch points.
The levers on the left control all signals for trains moving from left to right through the plant, the levers on the right control all signals for trains moving from right to left.
One of the most common uses of reverse loops in modern layout design is as part of a staging yard. The same method can be used with Digital Command Control (DCC) although there are other options for these systems as well.These same steps work for loops and all other reversing track sections including wyes and turntables. The only difference is you will not need to change the direction switch on the cab as the polarity in the rails no longer determines direction of travel. Do you want to sit at a dispatch panel and control signals, having trains automatically stop in sidings or at stations (the dispatcher perspective)?


The Multiple LEDs picture, shows how to wire multiple LEDs to 1 CL2N3, which is good for lighting coaches (passenger trains). Most of wjhat I have learned about Z scale is from the people who have been in that scale a long time.
After they are cleaned and dry, they can be used for holding parts of models that you’re in process of building or repairing. There are several within the control panel and some as well at the Tortoises (for frog powering and redundant switch signal lights (NJ International) on the layout at the mainline turnouts. That is one side of the switch motor goes to ground and the other side to your SPDT switch. Mostly traffic passing through the area, or mostly traffic coming from elsewhere to the area, or mostly traffic going from the area to elsewhere? Now if it had anything to do with your HVAC system or your ductwork I know all th answers and tricks of that trade, as I was a sheetmetal mechanic for over 40 yrs.
Remember to wash them well with soap and water to remove any make-up and then set them aside for a couple of days, until they are dry. The trays could also be used while you are creating scenery on you layout, for holding your small batch of plaster, extra water and your roll of plaster gauze, or you could use them for holding your washes when you’re coloring your scenery. The center tap from the switch goes to the Tortoise, and selects between either +12v DC or - 12v DC. The majority of two-rail track systems use a positive (+) voltage on one rail and a negative (-) on the other. Multiple feeders can be used on large reverse loops.Attach incoming power to either one of the other pairs.
An added advantage of these boards is that many also act as a circuit breaker and can avoid damaging a decoder or other expensive components.Wiring the Auto-ReverseWhile there are several versions available, most automatic reverse boards are simple to install. Your floor plan is a very good way to size just what you can have, but now you need to add building, industry, and scenery footprints along with it to get a better feel of what will work. If you take Elmer's diagream and put a circle around the diodes, with two wires sticking out to the sides, this is what you have. In an a reverse loop arrangement, the left rail will eventually touch the right rail and create a short circuit.The same rules hold true for other reversing track sections including wyes and turntables. Most varieties of readily available switches will be able to handle the voltage and amperage requirements of model trains. This can be a connection directly from the power supply or from the power bus that feeds the rest of the layout.
Most require only attaching two input wires from the non-reversing bus and two output wires to the reversing section. The LED holders are HLED-4, two part items where I only needed the external piece as it fit just right in the hole size I drilled for the LEDs. Only the table itself needs to reverse polarity, selecting A or B for the end of the bridge your engine will cross.The toggle switch will reverse the polarity of the rails in the reversing section once the train is in the loop. Some provide options to add resistors to increase sensitivity or add LED indicator lights for control panels. What you do is simply take a second one of these, and wire it in series between the LEDs shown and the Tortoise machine. This is a good option if you would like to be able to turn off power to the reversing section entirely. The pinstripe tape I used to mask the schematic lines is something I think I found on the internet or at the auto parts store. If the red and green point to the wrong direction, reverse the two wires going to the Tortoise.
Of course you can also stop the train prior to throwing the switches.It is always a good idea to leave the track turnout and the polarity switch oriented in the same direction. Flip the toggle and change the Tortoise, and the one that was red will now be green, and the green one will now show red. This is the simplest way to hook up LEDs to a Tortoise, no resistors are needed, just the LEDs.
