I have a strategy I have for LC+ and my new LC+2.0 from the new catalogue once I get it, which I will now share because I think it may help others besides me.
Lionel, IMO, has been great making repairs free of charge if anything goes wrong during the 1 year warranty period. However, I am nervous about repairs once the warranty period expires.
My strategy is as follows to reduce the need for LC+/LC+2.0 future repairs. I only run them for show, when I have an audience and to entertain my granddaughters.
For my daily runs, I mainly use my Postwar locomotives, which I also love, that are easy to maintain and get fixed. Arnold
