Many devices, such as the monorail, have been brought forward in the past to solve the problem of swift, smooth transportation. The latest, utilizing a single track, is reported in recent dispatches from Moscow, in the Soviet Republics (Russia) as in the stage of actual developmental work. The correspondent of the New York Times in that city recently viewed the demonstration track nearby, which was about a mile and a quarter in length. Here a wooden structure had been built, in a form of a groove about three feet wide, to receive the oval balls on which the train runs. The train itself, of five coaches, is streamlined. The experimental model ran around the track, smoothly and without vibration, taking sharp curves without difficulty.

The inventor, a young engineer named Nicholas Yarmochuk, has received authority, after his successful demonstration, to built fifteen miles of track, gauged to receive ball-wheels 80 inches in diameter (This exceeds even the wide gauge of Russian railroads). The track will be laid in reinforced concrete and, because the train accommodates itself to sharper grades and curves than will the ordinary type of railway car with trucks, the cost of construction will be materially less in difficult country.

The inventor declares that the final model, with highly-streamlined, enclosed trains, will have a running speed of 300 kilometers, or 190 miles an hour. For this, probably, motors will not be geared down, but as shown, built into the wheels themselves; thus reducing mechanical difficulties. At such speeds, also, the human element will be the deciding one as to the sharpness of curves; for a sudden turn affects the blood in the brain, and causes dizziness, as in stunting high-speed planes.
