I just had a thought after seeing some more dramatic images of molten trains on facebook;
I use KATO Unitrack.
Several of my trains (mostly, but not exclusively TOMIX ones such as Shinkansens) have electric couplers and pickups in each car, and are quite long. Is there a risk of overloading or short circuiting the trains when moving from one block to another with TNOS or with two different Power Packs (e.g. with the KATO double crossover, or with just one isolated block to another)?
Only talking about analogue operation with PWM.
Would really like to avoid finding out the hard way that I shouldn't have done something and having destroyed several of my trains or turning them into lava.
All of them are equipped with lights by the way.
I was also thinking of using 2 different Power Packs on the two diverging ends of one KATO #6 switch. Not a reversing loop; really two different Power Packs attached to each of the diverging ends, without using any insulators otherwise, so that the single track can be powered by a different Power Pack depending on the orientation of the switch. Would that cause any issues?
