THE EFFECT OF WIND PRESSURE.

In a recent scientific review, the writer, while admitting advantages

of the Bicycle System under ordinary circumstances, says: “A high gale

of wind striking against the sides of these two-story cars would press

them against the upper rail with a force which nothing could resist.”

Our present location should have given this matter the severest

possible test, located as we are in close proximity to the ocean and

exposed on a trestle over a mile long and high above the level of

the sea, where terrific gales of wind have swept against the sides

of the cars. We have as yet had no difficulty in keeping the track,

and have failed to perceive any signs of being carried away by this

“irresistible force” of which he speaks; on the other hand, we would

not answer for the safety of a standard gauge train passing over the

same place under like conditions, as instances of locomotives being

blown off the tracks and down embankments are authenticated. Certainly

a gale of wind which is strong enough to endanger Bicycle cars or

structures, would carry the heaviest standard gauge train off the track.

In the Bicycle System the trains as they pass along serve in a measure

to ballast the structure at the very point where the wind pressure

blowing against the sides of the cars would have any effect.
