Now Mr. Railroader, if you had to construct a line of road and were told that the old twin - rail system wouldn't do, how would you go about it? Pretty tough problem, eh?
Here's the way Mr. Kearney worked it out:
To eliminate lateral oscillation he used a single bearing rail --- a single - rail track. Above this, to keep the train on the track, he placed a guard - rail. The car is supplied with wheels both under and above it --- instead of both wheels being on the track, as in the present system, one set is on the track and the other on the guide - rail above. The car runs between the rails.
The guide - rails for the east and west lines --- the up and down lined, as English call them --- are braced together by horizontal lattice girders fourteen feet across. These girders are strong in the direction required, light in construction, easily assembled, and low in cost.
This supporting structure is carried on stanchions spaced sixty feet apart. On curves the entire structure is canted. The effect is the same as that obtained by the banked curves of a bicycle track.
For lines on which a speed of one hundred miles an hour is desired the bearing - rail --- the track --- would weigh from 80 to 100 pounds a yard, about the same as one rail of our present standard track. The overhead rail would weigh from 70 to 80 pounds a yard. The bearing rail would be bolted down to long sleeper running in the same direction as the rail, or supported on cross - ties of half the length now used. The supporting stanchions would be bolted down either to long sleepers anchored at each end of to concrete bases.
Because of war conditions it has been constructed. This is No. 1 of the Kearney System. Perhaps in the future it will be looked upon the car that caused a revolution in the science of transportation. Remember the Stourbridge Lion (see below 1)and the Atlantic, you doubting Thomases of the rail.
Don't laugh to soon!
