Everything looks great !!! Seeing your control panel I remember doing the same thing years ago. I'm thinking you're running DC ? I sometimes wish I would of stayed with DC. I have many many locomotives (steam) that are DC. I had a PFM Sound system years back so when DCC sound came out I was all in. But as time has gone by, and my modeling has gotten small (switching layout) most of my loco's are in the display case.
You have a Great layout, keep up the great work and look forward to more and more progress on your layout. Thanks for sharing.
