Hi Murleys All,
I loved your original post with the story of the history of the layout. And it appears that now you have been bitten by the year round layout bug! I loved the mention of Wheeler Ave and other Scranton area things as I was born just up the street, off of Wheeler at Butler St. in Dunmore.
I saw your mention of coming up with a method to replace pressure switches. Look into insulated outside rail control for your activation needs.
Your names and faces are familiar; Boys Scouts, If I recall?
Let me know if I can be of assistance in any way. You can find my email in my profile.
