Enjoy the Ho scale trains with O-O27 Plasticville building which are old family pieces. While it may not be a true to scale layout in the eyes of a detailed modeler, it does make for a decent Christmas display / layout around the tree.
The HO trains are all DCC they have replaced the old O, O-27 scale trains due to age also wear and tear. Over the past few years we moved to HO because we can run them virtually 24/7 without making a lot of noise also HO-Scale’s price is a fraction of what O scale has become.
FYI please excuse the outside motor hum noise which is from an air cleaner.
