I am recently retired and have two grand sons that are nuts about trains. My father bought me a train just after WW2. That train is a Lionel O Gage Engine 2025. My father was very into building train displays and had two trains himself. One O Gage and a HO Gage train.
I am now restoring the Lionel O Gage for my son's son and building up the HO Gage for my Daughter's son.
