JCV Woodland Scenics Grand Valley Railroad Layout Kit Update. WIRES, WIRES & more WIRES! + The Yard!

There are wires everywhere now but it is a very detailed and controlled madness thanks to ‪@KevinSquire‬ . His explanation of all that is below. Thomas killed it with the yard. John’s Layout Electrical Details We have separated the layout into 4 electrical blocks: Inside Loop Outside Loop Yard Engine Facility Each of those blocks have 1 or more power switches to kill power to that section. Inside Loop Outside Loop Siding from Inside Loop Yard Track A Yard Track B Engine Facility Track A Engine Facility Track B While there can be a lot of reasons for dividing a layout into multiple blocks, the main two reasons are (and the reasons we have done it even for this relatively small layout) - Limit a short from affecting the entire layout. A short in one section of the layout will not bring the entire layout to a stop, just the block where the short has occurred. By adding in the power switches, we also minimize the chance of a short happening while you are working on that area (ex: you turn the power off to the yard track when you are placing/replacing a locomotive on that track) Simplify Troubleshooting. Breaking the wiring into the 4 blocks, you make it easier to troubleshoot. You are able to focus in on the ‘troublesome’ block, and can ignore the rest of the layout. How it was done The main busline is on the board - in this case it is very short. For a larger layout, the 4 terminal blocks may be spread out over the entire layout (ex: each block might be along a different wall of the room). Each of those 4 terminal blocks are the ‘cutoff’ node to the sub-busline (“sub-bus”) for each block. So we have 1 “main bus” on the board, and that feeds 4 “sub-bus” lines. Those 4 sub-buslines go around the layout and connect to the track feeders. The track feeders are the small wires that are directly connected to the track and bring the electricity from under the table up to the rails. The various track pieces have been soldered together to form approximately 3ft to 4ft sections. Each section has its own pair of track feeders to connect to the sub-bus. We solder the track together because you should never trust the rail joiners to conduct electricity. They are not reliable electrical connectors due to temperature related expansion/contraction, as well as the chance of getting glue, paint, and other scenery materials down in between the joiner and the rails. The reason we don’t just solder every section together (to effectively make the entire layout 1 single piece of track) is we need to leave space for that temperature related expansion/contraction. Those expansion joints are done by connecting with just the joiners, i.e. no soldering. The joiners make sure the two sections stay in alignment during any expansion/contraction. The last part of creating the different blocks are the insulated joiners. While you can construct thing so that the wiring is all separated, the tracks on the layout are all connected. So you need to also electrically separate them as well. (otherwise you end up with just one block again). We have added insulated joiners at 8 different locations. The were added between the different block sections (ex: at the turnouts between the inside and outside loop) SPECIAL NOTE: While we don’t currently have it in place, these 4 nodes are where you would install your short detection devices (breakers, fuses, what evers). While we have put the infrastructure in place for your layout to have 4 separate blocks, currently it is all one ELECTRICAL block. As you add short detection devices, you will be ‘cutting’ up that block based on the number of devices you add. (ex: add some form of short detection on the “engine facility” section, and now you have 2 electrical blocks; the engine facility, and the rest of the layout. Add a second short detection device on the yard section, and now you have 3 electrical blocks. Etc. ) Videos/Resources related to the wiring and short detection (lots of similar videos out there, but I think Ron does nice job of explaining things) Ron’s "light bulb" option for short detection:    • Short Circuit Protection for Your Model Ra...   How wiring for DCC    • How To Wire A Model Railroad Layout For DCC   Breaking/districts for DCC    • How to Wire Your Model Railroad for Short ...   —------------------------------------ A more formal “short detection” device - the NCE EB-1 breaker: https://www.ncedcc.com/online-store/E... ======================================================== ** The light bulb really is just “detection” not a “breaker” When a short is detected, the lightbulb lights up, turning the extra electricity into light - but the electrical circuit is never cut or broken - it just is ‘redirected’. With a true “breaker” when a short is detected, the electrical circuit is cut or broken, so the electricity stops flowing completely.
