Let's talk about "buying used".
- most of us don't RUN our trains much. We are not like a restaurant or an office that turns on an overhead LGB train 12- 20 hours a day just for "ambiance". When I run trains, it is typically after a couple of hours working on the layout, when I sit down and run a few laps around just to watch trains and unwind, or show off the layout for 15 minutes.
- as hobbyists, many if us even have a real maintenance schedule - mine is once a year for all, and I write the date of maintenance (in pencil) on the bottom of the car of locomotive. Nutty?? Maybe. But for me at least that is part of the hobby's enjoyment. We clean, we oil. There is rarely any caked-up grease in OUR gears. And- the lubrication products are far better now than clay-based grease as used in 1950.
- Abuse. I used to run my Marx trains into a cabin built by my Lincoln Logs- just for fun. But the days where a Lionel train ran on the floor, on the carpet, and by only kids, is not as typical today. How many used trains have you bought in the last 15 years, that had carpet fuzz wrapped around the axles?? It is amazing that the things still run after 70 or more years!! The abuse of trains is far less, just because of the young kids' of today having a lowered interest level for trains.
- Sometimes, I like the features of the earlier 2000's engines better than those of the latest ones. I would rather have a 2008 Legacy diesel where the road number is built into the crewtalk, than a new one with opening doors and hatches. "Better" is a person's choice. But I have come to think things were pretty well done a few years ago, within the last 20 years. And, maybe the product made in Korea or Japan was better than what comes out of China.
- and the obvious: a used engine has already had all the troubleshooting and returns for service under warranty.
The point- when you buy used MAYBE the advantage of buying used makes that a more reasonable choice??
