By the use of social media, every blip, miscue, error, faux pas, etc. is almost instantly posted for the entire world to see.
Back in 1957 when I received and still own, my first Lionel train set, social media consisted of a couple of friends and cousins who had trains, the catalog, two hobby shops, and seasonal department store sales. Very limited exposure to the world of model railroading.
If the internet existed back then I imagine some of the topics would be what brand firecracker to use to blow up your trains, proper color of green paint to represent grass on your flat sheet of plywood, how to repair the cattle car, what train were you asking Santa Claus for, how many army men you could cram into a gondola.
Think of any other train topics from that era?
