Hello, As my unitrack layout is getting a bit complex, I decided to drop the "one turnout / one switch" idea to control several turnouts at a time so that one switch now defines a given pathway for a train, thus controlling potentially a fairly large number of turnouts (say from 4 to 10 typically). First, it seems the Kato power supply is a bit short in power and I find that switching simultaneously 6 or more turnouts leads to a non negligble speed drop (which I could already observe with the double crossover that includes 4 turnouts) of trains running on the layout. I intend to get a separate DC supply, probably 12V / 5A to avoid any issue. The reason I am writing this post is because when I use my switches as described above, I find myself in a situation where some turnouts will be controlled by several switches. See, for instance, the example below where I consider two switches : one for the red route and one for the yellow route. Both routes start from the same turnout. Assuming both the yellow and the red switches are connected to the same power supply, when I activate one switch, power will go through the turnouts but also through the yellow switch and vice versa. I found that this seems to short circuit my power supply (not always though). In order to avoid the power coming back through the other switch, I initially thought to use rectifier diodes but - I am quite new at this, I may be missing something... - the inversion of polarity at the exit of the switch seems to make this solution unfeasible. So here is my question : is there any way to control one turnout with several switches connected to the same power supply ? Thank you ! Alain

The publisher Sonic Powered made a series of six railway simulator games for the 3DS, each featuring a different line: http://www.sonicpowered.co.jp/train/ . They have announced the Eiden edition will be released in Japan for the Switch: https://japanesenintendo.com/2019/09/13/japanese-rail-sim-journey-to-kyoto-coming-to-switch/ . Unlike the 3DS, the Switch does not have region coding, so although the game will be in Japanese, you could play the physical version (as opposed to purchasing digitally) it on a Switch purchased anywhere. Also, they later released English language versions of the Eiden and Okinawa Monorail versions, maybe this will get the same treatment.

Hi I want control KATO switches (equiped with NCE SWITCH-KAT decoders) using SPROG III and JMRI, but have a problem. JMRI+SPROG control only double crossover, not a switches, everything works fine if I use MRC or NCE DCC system Any advice?
