Hi Marty-
I saw a posting on the Forum under another topic where Rudy from Lionel posted a link to the Lionel Layout Control System (LCS) site-- there I have found a lot of great info and a great index with FAQ's-- probably others already knew of this link but here it is again--- http://www.lionel.com/lcs/index.html
Just an update to this index needed by Lionel to add the newest CSM2 and Breakout Board introduced in 2018.
