Public Works: Railway Progress.—Nothing is so intimately 
connected with the commercial, industrial, and social life of the 
world as the great railway systems that run like arteries through 
all lands settled by progressive populations. One great feature 
of the railways has been the consistent and steady improvement 
that has been made in regard to the spreading out in the first 
- place of the iron ways, and then internally in the improvement of 
the permanent way, the bettering of the rolling stock, and the 
methods taken to ensure the safe working of the traffic, and to 
preserve from any danger the many millions of passengers who 
are carried annually. 
The earliest and latest railway appliances show wonderful 
changes in a comparatively short period. Contrast the young 
giant invented by Stephenson with the latest powerful engines 
running on the railways of our own Colony ; the light iron rails 
resting on stone blocks, with the substantial road of to-day; the 
open four-wheeled coaches of the Liverpool and Manchester Rail- 
way of 1830, with the latest Pullman Cars; the earliest goods 
waggons, with the most modern waggons of to-day; the very 
primitive signals of early days, with the complete system of 
signals and interlocking now in use. To attempt to give a 
history of the enormous development that has taken place would 
occupy too much time, and I shall therefore content myself by 
dealing with the improvements that have been made within the 
last few years in our local railway world. 
Probably the work of the greatest magnitude, and one that 
therefore most calls for attention, has been the quadruplication 
of the suburban line between Redfern and Homebush, which has 
only been opened as a completed work during the last few 
months. Yearly seventeen millions of passenger journeys are 
made over our suburban lines, the greater portion being made 
between Homebush and Sydney; and when it is remembered
