Cable-car" (notes edited by David Page) |
notes on the text |
Later, I began a vast but unsystematic exploration of the streets. I asked for no names. It was enough that the pavements were full of white men and women, the streets clanging with traffic, and that the restful roar of a great city rang in my ears. The cable-cars glided to all points of the compass. I took them one by one till I could go no farther. San Francisco has been pitched down on the sand-bunkers of the Bikaneer Desert. About one-fourth of it is ground reclaimed from the sea—any old-timer will tell you all about that. The remainder is ragged, unthrifty sand-hills, pegged down by houses.The San Francisco Cable-Cars
From an English point of view there has not been the least attempt at grading those hills, and indeed you might as well try to grade the hillocks of Sind. The cable-cars have for all practical purposes made San Francisco a dead level. They take no count of rise or fall, but slide equably on their appointed courses from one end to the other of a six-mile street. They turn corners almost at right angles; cross other lines, and, for aught I know, may run up the sides of houses. There is no visible agency of their flight; but once in a while you shall pass a five-storied building, humming with machinery that winds up an everlasting wire-cable, and the initiated will tell you that here is the mechanism. I gave up asking questions. If it pleases Providence to make a car run up and down a slit in the ground for many miles, and if for twopence-halfpenny I can ride in that car, why shall I seek the reasons of the miracle?
The system operates by the use of a steel cable which is running constantly in a channel under the street, the cable being guided by a series of pulleys and sheaves. The car runs on two tracks laid in the street, with a slot between them that gives access to the cable. A vice-like lever mechanism on the car called a grip is lowered into the slot, and when the gripman (or driver) pulls a lever, the grip is tightened and the car starts to move. To stop the car, the grip is released and if necessary, up to three brakes are applied as well.
