As a parent of an avid "Train Buddy" young son, our favorite train store was P &D Hobby Store in Fraser, MI. Fortunately, P & D is still operating, having numerous O gauge and O scale trains and equipment!
I was "released" early from my day job one New Years Eve Day, in about 1989. Later that afternoon, my son and I went to P & D Hobby, and the new Lionel Reading T-1 with Railsounds had just arrived. The staff was kind enough to repeatedly "test" the revolutionary sound system for the assembling crowd of onlookers. My son and I were: "like, totally impressed"!
My uber kind wife granted permission in a hurried call from my newly installed car cell phone (office supplied) to make a purchase, and my son and I played with the new engine until early into the following year. Our youngest son also joined in the fun in the train room. He was soon to be lost, however, along with his best friend, to the irresistable siren call of Nintendo's Super Mario Brothers and its progeny.
Early New Years morning, I did get into a little playful, not-too-serious, trouble with my wife for keeping our older son up too late. As I promised her, I was confident that he would still make it to adulthood, even after having missed a little sleep. Most fortunately, that prediction has come true, and he is still my Train Buddy, along with his young sons, who are passionate Thomas and Chuggington fans.
I recall being truly amazed and impressed with Lionel's RailSounds, as were the numerous visitors to my layout. The scale-sized Reading T-1 was also a stunner for the time period. (Thank you, Mr. Kughn and Mr. Wolf!) A new era in the hobby was definitely dawning.
