Mr. J. C. B. Moncrieff Chief Engineer for Railways, gave evidence before the Railways Standing   Committee on Tuesday in regard to railways through the Murray lands. He said the extra cost of the construction of the Waikerie, Loxton, Paringa, and Peebinga lines on a grade of 1 in 80 would have been £62,644 at the time and now it would be £202,900. The cost of substituting   60-lb rails for 40-lb rails would be heavy       because it would be practically impossible to dispose     of the 40-lb rails as they were being discarded     by all the states. Possibly they could   be sold at £400 per mile. The present sleepers   could be used for 60-lb rails, but an extra 132   to the mile would be needed.  

Questioned regarding the heaviest train that could be hauled over the bridge at Murray Bridge, the witness said the governing factor in regard to the strength or capacity of a bridge was the axle load and in respect to Murray Bridge that was 13 tons 2 cwt., which represented the   heaviest engine in use at present. It was practically impossible to strengthen the bridge, which     meant that heavier engines could not be run over   it. The difficulty was that the bridge was ori-  

ginally deigned for road traffic and was then altered for a railway bridge. Before the bridge.     was constructed he believed a further alteration         was made to made to it capable of carrying the 5   ft. 3 in. gauge line instead of the 3 ft. 6 in. gauge, as was intended. The weak point in   regard to the construction of the bridge was the     strength of the girders, and in regard to foundations the approach on the far side of the river.   A slight settlement was still taking place, but the subsidence had been small during the past   four or five years as the speed of the trains had  

been reduced. Since the bridge was constructed    

the settlement in places had been as much as 4 ft.    

6 in. The bad places on the Murray lines could       not be regraded without altering the ruling grade in order to obviate jerks at changes of grades.

The removal of the bad parts would result in   addtional cost without any compensating advantage    

in the working of the line.  

Mr. Reidy-To the layman that is extraordinary, because we went over certain pinches ? -The cost of doing the work piecemeal will be more, and   the advantage will not be apparent, because     there will be other pinches, which the layman   cannot see now. You will then get other   places 1 in 45 the pressure on the engines would be the same, and you would not increase the loading.  

It would make the line more comfortable   for passengers, but would not improve the  


The witness said that in view of the heavy loss on the present Murray lands the Committee would  

not be justified in recommending the construction      

of narrow gauge feeder lines.
