From the Kearney Files
Sydney 11th November 1921
AN ENGINEERING FEAT
To walk down a few steps at the foot of Pitt Street, Sydney, into a brightly lighted subway station; there enter a train, and, in less time than it now takes to take a foothold of the ferry, to be whirled across or at least underneath the harbour to Milson's Point at the rate of 60 miles an hour -- these are not it seems, visions of the future, but are rendered possible by a project which Mr. E. W. Chalmers Kearney M. S. E., the inventor of the Kearney High Speed tube, hopes to see successfully accomplished soon.
For many years proposals have been made for the linking up of Sydney and North Sydney by bridge or tunnel, or both. The present intention is to make a high - level bridge between Dawes's Point and Milson's Point, but the high cost and the long period for construction are calculated to provide sufficient evidence to excite interest in the alternative Kearney scheme. The Kearney high speed railway trains run on a single rail, and are kept in position by a single overhead guide rail. It is estimated that the journey from Circular Quay to Milson's Point would occupy 70 seconds to travel across the harbour, whereas the ferry takes 10 minutes to travel across the harbour. No electric trains in the world, it is said could give the service Mr. Kearney proposed without the use of steep gradients to help it gain speed after starting, and to slow up before stopping. To allow the use of gravity to the utmost the Kearney system was devised, and the Kearney system was devised and it's inventor has thus scored a signal success in engineering. A model of the proposed tube has been constructed and the system has been worked out on the full - scale. The car, which is available for dispatch to Sydney for demonstration immediately, is 45fert long and accommodates 44 passengers. Eight cars would be run on a train in rush hours. All doors would be electro - pneumatically, so that they could be opened and closed by one conductor. There would however, be two drivers on the train during busy periods, so that no time should be lost changing ends. The total capacity of the eight car train would be, 1,000 including standing room; thus with a three minute service 20,000 passengers could be transported in either direction in an hour.
Mr. Kearney says that in advocating the tube, he does not wish it to be supposed that he is opposing the suggested bridge, but so far as passengers are concerned, the tube could accomplish at one - tenth the cost all that a bridge could do, could be installed in one - sixth the time and could transport passengers at least five times as fast.
