Just an FYI,
Browsing though the Shack, I found a nice 12v 3A transformer.
12.6V CT 3.0A Chassis-Mount Transformer with Leads 273-1511 for $11.99
I figured that 3 amps was plenty for my micro-pizza layout, so I decided to install it under one of the buildings. Now there is just a power cord that I plug in the wall. It provides 12v for the 14V lights in the buildings and the switcher with smoke unit on. 12 volts is just right for the K-Line switcher and for a Beep I tried.
I thought I'd share. This might be an easy way to power a small layout!... correction: VERY SMALL LAYOUT
To make the layout more portable, I attached most of the items to the layout so it's easier to just pickup and carry. Buildings, cars, telephone poles are all attached. I took the layout to our club Open House on Saturday. 2 minute setup.
