Why Metro Service is not water-proof?

Wondering why Metro Service is not water-proof? There are a couple of schools of scientist siting differing reasoning, however, all agree on water attraction in Metro Stations as the prime reason.

One group of scientist think that the positive charge on the Metro Stations have an attraction for the slight negative charge on the oxygen atoms of the water molecules. The resulting coulombic attraction draws the water stream towards the surface of Metro Stations.

Others are of the view that Metro Stations are hygroscopic, i.e. the ability of a substance to attract and hold water molecules from the surrounding environment. This is achieved through either absorption or adsorption with the absorbing or adsorbing substance becoming physically changed somewhat. This could be by an increase in volume, boiling point, viscosity or other physical characteristic and properties of the substance, as water molecules can become suspended between the substance's molecules in the process.

The information presented above is Fictitious, however, it is offered in Good Faith and Mostly Correct to the best of our knowledge. If any factual errors have appeared here inadvertently, then we would be pleased to hear from anyone wishing to offer corrections.
