This is an insane track.

Of course! I remember doing that as a kid. We had enough cars that the front of the loco could couple back on tot he rear of the caboose if I wanted to. It was fun trying to see which locos could pull that many cars. The Tycos with traction tires, no big surprise. But then some of the other stuff - like the old Tyco 0-6-0, all metal. Or the Flyer HO industrial diesel - also all-metal. The ones without traction tires would slip like crazy but eventually get it moving. Other locos, like a Rivarossi Docksider, had no chance. Light weight and no traction tires.
It was an interesting diversion. After a while I got bored and took off the excess cars and went back to running trains in a more 'normal' fashion, making meets at the passing sidings and dropping off cars at industries. Though my latest layout will be intended for operations, and I don't really have room to build it to handle more than about 10 car trains, you can bet at some point I will link multiple trains just to see what I can pull around the whole thing.
Life is too serious anyway, can't be completely 100% serious at all times in hobby pursuits as well.
