When I upgraded from a Powercab to NCE's SB3 to get another amp, I experienced a behavior difference.  When taking trains on and off the track, I disable the track connection with a master switch (rather than turning off the power to the DCC unit).   With the SB3 when I restore the track connection, the unit turns itself off.  This happens when I have a number of cars on the track lighted with incandescents.   No problem if I cut and restore the DCC power supply.Being I have around 800 ma of incandescents, I was suspicious of the inrush.  NCE confirmed the SB3 is more sensitive to inrush and said the solution is to put an auto light bulb in line with one of the track leads.I'm curious why this works.Thanks, Bob
