No explanation I can figure out, it isn't a PZB Zwansbremsung-- but first I lose all poewer, then the brakes slam on. What's going on?
It's not the Sifa? It doesn't sound that you take to much amps, that will not activate the brakes. What speed do you run?
apparently, you have to apply the power to the train gradually. If you power it all at once it will shut down. I don’t know a solution.
