The author describes the efforts it took to get the locomotive, how fascinating it is, and then concludes with this paragraph:
Now maybe you’re not into model trains, but consider this. If you walked into a store today, how much of what you see for sale could reasonably be expected to still be working 60 years later? How much of it could be repaired if it broke — and could you find someone to repair it and the parts as well? How much of it could still work in the world 60 years from now? That engine of mine will operate on the track and systems now available today. It’s something to think about in a world where so much is ‘disposable’, as is the fact that Lionel Trains is still around when so many companies have disappeared.
