I don’t know how modern manufactured locos are designed to operate but it seems the “post war” locos are doing what they were designed to do. A break or sudden change in voltage trips a relay that cycles through forward, idle, reverse, idle, forward, etc.. Perhaps a capacitor could make them less susceptible to sudden voltage changes, but I’d think one would want to have the voltage pretty well matched to avoid sudden changes in speed even if you didn’t trigger the relay. Many post war locos had a switch that would bypass the relay, so it won’t cycle but stay in the mode it was in when the switch was thrown. That way it won’t go to idle on changing to a mismatched block, but then you’d have to throw the switch back again to be able to reverse.
