I got some extra track and power goodies on order. Now the waiting.
My MTH train is still in the shop getting it's board replaced/upgraded from 2.0 to 3.0. So, I waited on the MTH Commander. I'll get that when the train is ready (boards are on backorder).
I went ahead and got a PowerHouse 185 (more is ALWAYS better, right???) and the TMCC lock-on.
I'll figure out how to most easily add power drops once everything gets here. I've got lots of electrical supplies/wire/etc already.
Thanks again for all the help!!!
