The maximum loading space of the similar 2 feet waggon is- 

 600 cubic feet, and its maximum weight carrying capacity is 10 

 tons. 



Working out the proportions between the live and dead 

 load (waggons only) for the two gauges, we find them to be a& 

 under, bearing in mind that we are now dealing with up traffic 

 only :—

We shall illustrate this now by an example. Assuming one 

 standard gauge train on a branch line, with a nett or paying 

 load of 100 tons, made up in the proportions previously given, 

 viz., 42 tons of grain, 14 tons of hay, and 17 tons of wool, 14 

 tons of cattle, and 13 tons of sheep. Taking the dead loads 

 corresponding to these, as above, we get 19 tons of truck weight 

 for the grain, and 21 tons, 11 tons, 17 tons, and 38 tons respec- 

 tively for the rest, summing up to 100 tons for the load, and 

 106 tons for the waggons, total 206 tons. The railway reports 

 show that the back or return loading in N.S.W. is, roughly, 

 about ^ of the weight of the up loading, so that the average for 



the double journey would be = 60 tons live load, and 



A 



106 tons dead. 



Suppose, now, for the branch, we take an average traffic of 

 6 trains per week, each way. It is true that as small a traffic as 

 is represented by half that running, exists on some lines which 

 have been constructed, but either these have been mistakes, or 

 they run through, as yet, undeveloped districts, with which our
