NW-Modeling-List Digest, Vol 205, Issue 40

Thu Apr 2 12:44:10 EDT 2020

The 2014 video on installing Tortise switch machines AFTER you've forgotten
to install them BEFORE the track work was great!!!  I've put this off for
too long, and since I'm forcibly at home I MUST work on the layout😏.
Thank you!
