Dcc consist speed matching Aug 7, 2012 · Then consist using Command Station assisted consist would certainly work, the shunter at "full" speed, and the AL5 at "half" speed. The Jun 28, 2017 · H'mmm. Not sure how different decoders would behave on half-speed and decoder assisted consists (CV19). ) Feb 21, 2021 · I have a question about consisting and speed matching. My method requires nothing more than a cheap stopwatch and 3 distance markers (I use plastic bulletin board tacks with the pins cut off). Adjust CV2 so the loco runs the same in both May 27, 2024 · - Run your loco through the speed reader at full throttle to establish the top speed. The second big gotcha is that Bachmann factory decoders do not support all NMRA DCC CVs, including those that support speed matching. To make the speed matching easier I set CV 3 and 4 to 0 so the momentum effect would be gone. It would vary the characteristics of each engine, at each speed setting, and within a few minutes of tweaking they would operate as one. In an ideal world, I could instruct the DCC system to perform a Speed Match function. ” In trying to figure out the best way to do this, I found that online information and magazine articles are typically written for the "plain vanilla" case of speed matching a pair of identical locomotives. I always tune the locomotive performance using BEMF, start voltage, etc, to get the locomotive to run as well as it can before I set up any consists. This has happened maybe a half dozen times over the last 6 months. I can say with 100% certainty that it is possible to speed match and consist Kato locos with Digitrax decoders with BEMF enabled. In addition to speed matching, Dan gives a brief rundown of DCC programming, and takes a stab at explaining CV29. Feb 24, 2022 · Most model railroaders are aware of speed matching but also have only a basic concept of what is required to do it and know even less about what they can do . An important task before creating a consist is to ensure that all locomotives within a consist run the same speed. Any suggestions are welcome. Before I start to speed match loco’s I set CV’s 3 and 4 to 0, these are acceleration and deceleration CV’s. Dec 22, 2023 · Observations are anecdotal. This is helpful if you want to run a consist (multiple locomotives running in the same train) or just want your engine fleet to respond the same way to a given throttle input. Is it better to speed match the locos before consisting or create the consist and then speed match. Next set CV2 (start speed)so the loco’s just begin to move on speed step 1. Change the Start Voltage (aka VMin or CV2 … or CV67 if you are using the speed tables) by adjusting it so that the Slower one matches the faster. 2 specifies all decoders provide CV2 (V start), optional are CV5 (V High) and CV6 (V Mid). I am reluctant to start changing the CVs to adjust the start speed when they seem nearly identical UNTIL I put them in a consist. There are two generic consist managers, one uses operations mode programming to change CV19, and the other sends a special DCC packet to change CV19. (CV-21 and CV-22 can fix this. SPEED CONTROL speed matching the locomotives. Connecticut Valley Railroad -- A Branch of the New York, New Haven, And Hartford Feb 24, 2018 · Basic dcc programming and speed matching on NCE Here's the second installation of my DCC programming videos. Speed matching is adjusting the locomotives in the fleet to run at the same speed for a given throttle setting. These three CVs are active when Bit 4 of CV29 (Speed Table Enable) is 0. that way, setting up the consist is much easier. Your DCC system’s instruction manual should explain the method. (The Soundtraxx decoders that come with the Sound Value Bachmann range do support all speed matching CVs, although some sound-related CVs aren't supported. Do you want to set up your model train locomotives to play nice with each other while running on DCC? In this episode Dan explains his techniques for speed There are a number of videos and tutorials on the web demonstrating speed matching using the speed tables in the multifunction decoders. It is also possible (and in fact easier) to get excellent slow speed performance with BEMF enabled. Dec 18, 2014 · Speed Match them at Speed Step 1. Preparing model locomotives for consisting can be a challenge. My whol Nov 9, 2013 · Speed matching is recommended. Jul 26, 2020 · I was speed matching three locomotives that have a Loksound v4, 5 and 5 DCC. When I run either locomotive, not in a consist, it seems that the start speed is very, very close. Dec 13, 2021 · Speed matched locomotives are calibrated to run at the same speed at any given throttle setting. Sep 23, 2014 · The speed matching is a very valid reason to go to DCC particularly if you've got a lot of goofy stuff to MU, but you still have to determine the master you're matching against - which sometimes isn't any easier than the non-digital blacksmith stuff I resort to. Speed Matching Main article: Speed Matching Locomotives. Dec 18, 2014 · Most DCC systems keep track of which locomotive is the lead unit and allow functions only on the lead locomotive to be controlled with the consist address. Aug 19, 2008 · Since most model locomotives run at prototypically high speeds, and different models usually run at different speeds, it is worthwhile to match the speeds of your locomotives, especially if you wish to MU them in varying combinations. 2. Dec 12, 2013 · variation in speed using my Bachmann EZ DCC controller which has no ability decoders to different addresses in a 2 loco consist for speed matching would work fine. If both directions are the same, no problem. I have an NCE power cab. Dec 18, 2014 · Many guys choose to use the same DCC address for all locos in a consist of this type – if you are going to do that it is easier if you speed match them first with separate addresses … and then set the addresses when the speed matching is complete. ) Nesting Consists are a combination of types of consists and the Universal part must be reestablished when a consist is moved. Try the loco in both directions as they may run differently in reverse. NMRA S9. Dec 7, 2022 · On DCC equipped locos, speed matching involves setting three configuration variables, CV2 (Vstart), CV5 (Vmax) and CV6 (Vmid) for each loco. If the reverse is slower or faster than the forward, change the number in the reverse trim window a few numbers at a time in the appropriate direction until the loco matches the forward speed. Aug 7, 2022 · See if speed matching DCC locomotives with CV2, CV5, and CV6 do it for you. But when I consist them, the GP9 runs, and the GP7 just sits there. I tried speed matching before consisting and got the locos to be close in speed, but when I consisted they were not running close. In both cases I had to use my brake function to bring the locomotives to a full stop. The Generic Consist Managers are used on any system which does not have it's own consist manager, but supports either operations mode programming or a sending raw DCC packets. Or youo could pick up a copy of the December 2022 issue of Model Railroader magazine which has an article on it on page 18. Note I said "setting up the consist" and not speed matching. This will result in tug-of-war between locos, or a push/pull between the locos. Over the last 6 months I have had to speed match a consist again somewhere between 3 to 6 times. Her Mar 2, 2018 · Do your best to match the speeds by programming each loco independently, then use your DCC system to consist them together with a separate consist number. To my surprize CV4 set to 0 had no effect on both the Loksound 5 and Loksound 5 DCC. Dan uses N scale locomotives as examples in this one, but the techniques apply to other scales as well. If you want to know more about speed matching DCC locomotives, check out Larry Puckett’s DCC Corner column “Speed matching for DCC consists” in our September 2016 issue . See full list on dccwiki. This method applies DCC Speed Matching Theory • Utilizing capabilities of DCC decoders in two ways, we can speed match various locomotives: – 2nd method…Use the 28-step speed table built into most DCC decoders – Using special Speed Matching Script with JMRI software and the speed match layout – Allows for easy method of setting the 28-step speed In this video I show you my secrets to speed matching locomotives using JMRI Decoder Pro. There's still be some speed matching to sort it out, but the ranges might at least overlap. I am using the Advanced Consist feature. Then as the engines run as a consist, the CV values are constantly updated to improve performance. Match the slower locomotive – at SS1 – to the fastest one. speed match needs to be much better than “close enough. All of the consists have been speed matched, and at the time that I did it I was satisfied that they ran together relatively smoothly. The explanation portion of this video is likely overkill, so I hope it wasn't confusing. com Aug 12, 2022 · Making sure the same speed step result in roughly the same speed is called speed matching. Speed Matching Consisting Engines of Different Manufacturers Using DCC/DecoderPro (Provided by Keith Keith Albright of the Four County Society of Model Engineers) In most cases, DCC has made it easy to consist engines that could not be run together in analog mode. Nov 14, 2020 · I have over 30 consists of 3+ locomotives on my railroad, and have set up many more. Comparing your locomotives’ responses to different speed steps and tweaking CV2 (Vstart), CV5 (Vmax), and CV6 (Vmid) will usually yield speed curves close enough to each other for most modelers. If you don't do this, some locos will run significantly faster than others. Notes on Various Manufacturers. vmtt rmscxeo cbomm ukusxkf xgllljy gqjoe usp mqin tfic hgvb agvy rmcctu xfeqbr vvrwsa lvbd
