Hey all, Thought you might like to see the power panel i'm building for my home layout. It has 4 track blocks plus 1 accessory power block. So 5 separate transformers. I'm using all Lionel TPC units: 4 TCP 300s and one TPC 400. Enjoy, Stevo. http://www.aoot.com/pics/Tonkowa/Train_Room/2009-08-18_Power_Panel/
