ran some then needed more places to park trains so reworked the upper level to add 2 sidings. then figured it was time to finally run the wires for the switches and mount them on a control panel and make the panel . so I spent 3/4 of the day under the layout then My granddaughter wanted to run Thomas so I made a loop under the layout for Thomas to run on and she had a ball with Thomas ended up wiring 6 switches running all the wires to one spot
