I recently bought a couple of the black side-dump ore cars (92503). Very nice, but I was wondering: Are the chains meant to dangle freely, or should they be attached to the chassis in some manner?
The chains are used to prevent tipping and thus unloading of the car while in transit. There are large hooks at the bottom / end of the frame. The chains hook over them. When the car gets to the dumpsite, the chains opposite the desired dump side are unhooked, the car is dumped, then the chains are refastened. The chains should always be fastened, except when unloading.
Happy RRing,
