In 1950 when I was 7 years old, I got my very first train set and I still have it (pictured in the attachment). The set was made up of an AT&SF switcher engine (6220), an NYC Gondola car (6462), an AT&SF operating box car (63132), a Lionel Lines Searchlight car minus the search light lost over the decades (6520), a Lionel Lines operating crane car (6460), and a Lionel Lines work caboose (6419). The engine was reconditioned some 25 years ago and still runs and I, through Trainland, was able to locate a replacement searchlight car also 6520 which I will pick up this week.
The whole set is almost 69 years old.
