Plarail Disney Monorail sets, worth it?

Just a warning, I bought a new old stock and the gears broke during the first minute of running. Gear might have been brittle due to age.

Evan did enjoy it just pushing it around the track

Wow. Yeah I was wondering, because almost all of the used ones seem to report they turn on but then do not move, or make a grinding noise. I have no doubt I could possibly fix it, but will they keep breaking? ... Maybe.. Maybe if I find a good deal on a lot or something I guess they would still be worth a shot.
