It all started with a Lionel 0-27 set for Christmas in 1958. It had a Wabash Geep and a few cars. My dad and brother in law finally let ME play “trains” after a few hours, and I guess I haven’t stopped yet. I did switch to HO in the 70’s for space consideration. I am currently building a 2’ x 10’ “around the room” shelf layout to get my 6 year old grandson interested.
