Here's my Marx 666 - nearly 63 years old and still running strong! It was my first train (Christmas 1958), part of a Sears Allstate set. In this first photo, we see Samantha guarding it and the Christmas tree (circa 2015?).
Remaining photos were taken on Panhandle 1. I ran it there in conventional mode using a TPC-400 and CAB-1.
