Block power surges


Recommended Posts

I'm looking for a solution for DC Kato Unitrack to get rid of surges (or whatever you call it) when changing blocks powered by different voltage.

The metal wheels of cars + lighting prep connects the two section long after the loco passed the insulator and the motor doesn't run well.

I know this is usually avoided by changing the block sources so that they are powered by the same source but that's not gonna work for me.

I'm trying to use a Voltage regulator to limit train speed in stations.
The way I understand it, I'd need to insulate a part of the track longer than the longest car, which the loco would then struggle with.


Any tips?

Problem resolved. It was caused by something else.

@Tyraforce Curious what was causing it. It’s always good to hear potential issues out there someone else may run into later.






I figgured out the power bridging problems. What confussed me was that the Glacie Express cars don't have lighting prep while all the other RhB cars do. The lighting prep includes 2 pieces of metal connecting all wheels on each side of the train thus creating a bridge that caused all the jerks while crossing to a block with different voltage.

I suppose when I cut connections to one side of the train, I'll get worse lighting quality but it should get rid of most of the bridging problems.

Could look at putting a capacitor on each side to help with flicker few small tantalium caps across the power strips should help.
