    Technical problem 9V

    So if I understand you right, the "leakage" in your case @aawsum is not due to problems with switches but rather due to construction/setup circumstances with your layout (which at least to me is good news...) I assume that these circumstances eventually also could cause derailings. My advice would be to spend more time and effort on wires and tables in order to get rid of the root causes behind your "leaking" and other problems.

    Technical problem 9V

    Thanks @Toastie for sharing your own experiences. Yes, I would have been surprised to learn about leaking non-modified switches (unless they have been damaged one way or an other). Interesting to read your short circuit case with rather dramatic consequences. It appears to me that you must have missed adequate fuses with your permanent power supply. Standard - including my modded - 9V speed regulators include termo fuses which automatically interrupt power supply in case of short circuit. I guess a safety precaution since the 9V system with its open power supply to the 9V engines originally was developed for children. That's why I was surprised to read about this "leaking" issue. Using 9V speed regulators, it's either on or off, straight or switch - nothing in between. That's at least my understanding. And yes, modifying 9V switches is tricky and requires full attention and accuracy. PS: 15V/10A 150W permanent power supply on your layout?!? A Lego 9V train engine at full speed requires approximately 350mA. 10A would theoretically be enough to run 30 9V engines at the same time at full speed ... So what's the basic idea behind 10A permanent power supply? Why 15V? What is the maximum voltage tolerance for 9V engines? By comparison, on my 9V Extreme layout, I use 4 modified 9V speed regulators with LM350T regulators that can provide up to 3A each. This means that, theoretically, I could run 4 trains with 10 9V engines each at full speed (alt.13 engines at medium speed as on the Swedish Iron Ore Train) which all in all would require approx. 12A. Still less than half of what the Voltcraft EP-925 Linear Regulated Power Supply unit can provide (3-15V/DC, 2-25A 375W). However, the difference here is that the Voltcraft will only provide as much power as is required/needed. No risk for overheated rails. And with the outside heatsinks, LM350T temperature increase is well under controll.

    Technical problem 9V

    I need to get back to @aawsums comment re. "leaking" switches. All in all, I have been using almost 50 switches - incl. crossovers and halfcurves - over the past 25 years and never experienced any "leaks". Based on your experience, what are the reasons behind leaking switches?

    Technical problem 9V

    The basic idea with this layout - as with the 9V Extreme layout - is to provide the possibility to run several trains simultaneously, and independant from each other, by using multiple speed regulators for different segments.This can be done with all switches in straight position, thereby eliminating interference with opposite polarity. As mentionned above, the original problem - caused by inaccurately connecting all minus cables together - is now solved and it is now possible to run 3 trains at the same time without conflicting polarities.

    As mentionned above, I use two modified and two standard speed regulators:

    Technical problem 9V

    This is exactly the reason for this problem! When mounting the minus cbles and connecting the four blocks, I was absolutely sure I had done it the same way on the 9V Extreme track, which I haven't.... So this is how it looks now. Problem solved! Another sign of growing dementia...? Thank you guys for all your help and attention. And sorry for taking up your time for such a stupidity.....

    Technical problem 9V

    The siding at the lower part of the schedule is dedicated to an "Airport Shuttle", a rather short train with two engines. The purpose of having both Regulator A and Regulator D on the same track segment is to make it possible to run also long trains with 4 engines or more - e.g. the TEE VT11.5 - all the way up to the Airport level. All power connections with nomenclature A are operated by Regulator A (both plus and minus). Connections B are operated by Regulator B etc. Notice that Regulator A and Regulator B are modified and equipped with LM350T regulators, 3A diodes and outside heatsinks to allow for trains with up to 10 engines. Regulator C and D are standard 9V speed regulators. In comparison, the 9V Extreme track is operated with four modified speed regulators.

    I just added a schedule. I am aware of reversed polarities when changing dial positions. That doesn't answer the question of interference between the various tracks, or?

    Technical problem 9V

    On my new layout, I have now displayed four tracks that are operated individually with a 9V speed regulator each. All power connections to the rails have been checked w.r.t. polarization. Conceptually, the setup is equal to the Lego Train 9V Extreme display, including crossover swiches linking these tracks together. The basic idea is to run trains on these four tracks independent from each other in elective directions. The first tests showed no problems. However, these initial tests were performed with one train at a time. Recently I started to run several trains at the same time. Then I discovered that there seems to be some kind of interference between all four tracks. When running trains in opposite directions, the engines slow down or come to a stop. Notice that all crossover switches are in straight position. When operating the four speed regulators, they work only on the designed tracks, i.e. there is no visible interference at all in terms of other engines on other tracks would start running simultaneously. I just don't understand this problem, particularly considering the fact that I have never experienced similar problems on the Lego Train 9V Extreme track. Any advise to get this problem solved would be highly appreciated! Below a schedule over this layout with positions of the power connections to the track

    Rail Cleaning Train - Latest Version

    I just love this forum!! Thank you so much guys for all your comments and suggestions - some of them quite "tangential" indeed ... All this knowledge and experience - ombined with thinking outside the box! Simply fantastic! As for rail cleaning I will go for 70% isopropyl alcohol. When it comes to track cleaning, att some point in time I have to consider vacuum-cleaning rather than spreading dust by using compressed air... W.r.t. train cleaning and compressed air, I will revert back with a separate topic just on this matter! Great to hear your suggestion @zephyr1934 re the rotary snow plow. I mentionned this idea some years ago to my wife as part of introducing "climate" to my track, e.g. artificial snow. This idea is definitely dead...

    A guy in Sweden mentionned that methylated spirit includes small quantities of aceton, something he advised against (but never had used for such purposes). Based on your experience, Andy, I will start using methylated spirit from now on, both on cleaning unit type I and III.

    Thanks for your comments, Andy and legoboy. Just received a similar comment from a guy in Sweden who suggested using white spirit on cotton wool. What kind of alcohol are you using (for cleaning purposes of course ...)

    Rail Cleaning Train - Latest Version

    Interesting. So far, I have been running the cleaning pads dry, primarily in order not to chemically damage the rail plastic. I still remember discussions some years ago re lubricants and the potential risks to damage Legos plastic. Haven't thought about using alcohol. What kind of alcohol do you use for cleaning purpose? Would white spirit work? Cleaning in general has become a major theme w.r.t. the entire layout - and the trains. Using compressed air is an excellent way to get rid of dust, particularly on trains!
