Given the high cost of official Lego monorail track, I was wondering how long it tends to last/if there are any maintenance tips or tricks? I'm planning on using power functions to reduce the start/stop strain, but is there anything else to increase longevity?
Try to keep the track in mint condition. For example, don't expose it to extreme heat or cold. Keep it away from any pets or children who don't know better. Looking at some pictures, it seems that the vehicle on the monorail runs on a gear. Try interchanging gears every so often so that the gears don't wear and the teeth don't get bent or break.
The track is pretty durable. I have several pieces of old track that the motor runs on well. With the 3D printers now available I am hoping to be able to "print" some of the track with ABS filament. Getting the gear teeth just right will be the tricky part and the end connectors.
