Thanks for the reply.
Research indicates that other users of the SC-2 with switches have modified their own units, and that is probably what Lionel will do.

Reading through the manuals of both the switches and the SC-2, it seems the issue affects those that wish to power the SC-2 with the EXTERNAL wallpack power supply when using it for switches. It seems THAT is the only time that port #1 can not be used for a switch, because the SC-2 power is in conflict with the switch power in port#1. When powering the SC-2 from switch power, you MUST use port #1 , or the SC-2 will be DEAD.

I would not hesitate to power 6 switches through the SC-2 as it is unmodified, as long as you DO NOT use the wallpack to power the SC-2.

I would contact Lionel service again, and ask them about the scenario I just described, and if it would work without modifying the SC-2.
