For the last 24 Christmases I have hosted my entire 26 member family for what we (I) call the annual family train party. As a 'thank you', my brother and his wife each year gifted to me a very unique train ornament for the tree. Here are some images of them on the tree from 2018. Each ornament has either a built-in date or a hand written date for the year, and if hand written, the # of the train party.
I couldn't get closer to the tree, so sorry that things are a bit small.
