Ballast in shipping terms, not railway, refers to weight added to a vessel that is in a light condition (free of cargo), to maintain stability. When loading, the ballast is discharged in proportion to the cargo taken aboard. In sailing days, stones were used, which is why port towns or cities have cobblestone streets, and buildings. In modern times, ships use seawater in segregated ballast tanks for this purpose. On making landfall, the ballast water is dicharged, and refilled before entering a harbor to avoid foreign marine life from entering our waterways ie zebra mussles.weight to keep boat stable, usually located low down
water that is taken aboard in tanks to aid stabillity

Sail boats are powered by the wind (Captain Obvious HERE)
Most land lubbers do not realize that a sail and mast attached to a regular boat will cause it to be tipped over when a strong wind blows. Sail boats have a keel or centerboard system that extends down into the water several feet. A sail boat may only sit 3 or 4 feet out of the water. Not counting mast height. However there is normally a Lead keel that extends 6 or 7 feet below the water. This is made of lead for "ballast". The length also gives lev erage against the force of the wind.

On larger ships (ie Tankers in particular) the ballast would be sea water pumped into the tanks that would normally carry fuel or oil as cargo, but when this has been unloaded the tanker would fill the tanks with sea water to keep her lower in the water and thus more stable.
