together with a motor-booster ; the line is worked on the overhead | 
trolley system, in the design of which simplicity and unobtrusive- 
ness were specially considered. No trouble has been experienced 
in working, although, owing to the sharp curves, great care had to 
be exercised in carrying out the overhead work. Approval for 
the construction of the Willoughby (Sydney) Electric Tramway 
was given on the 16th December, 1896, when it was decided to 
convert that portion of the Cable Tramway beyond the Power 
House at Ridge-street, North Sydney to electric traction, a dis- 
tance of sixty chains, thence to Victoria Avenue, Willoughby; 
length of line two miles forty-five chains. This work is at present 
being carried out. The generator will be driven off the main 
engines in the power house at Ridge-street, and an accumulator 
house containing two hundred and fifteen cells erected on a piece 
of land situated about midway between the power house and the 
terminus of the line. The overhead work will be of the same 
type as that used on the Mosman’s Bay Electric Sch Wen and 
which has worked so successfully. 
Approval for the construction of an Electric Tramway from the 
terminus of the Ocean-street (Sydney) Cable Tramway to Rose 
Bay was given on 19th January 1897; the length of the line is 
one mile twenty chains, Preparations are now being made for 
the carrying out of the work. The generators, of which there are 
two, will be driven off the main cable engines at Rushcutter’s Bay, 
as a means of using some of the surplus power, these engines 
having proved to be even more economical in working than was 
expected. The overhead construction will be similar to that which 
will be used on the George-street Tramway with the exception of 
the poles, which will be of tallow-wood. A battery of storage cells 
will be erected in the engine room at Rushcutter’s Bay, and 
advantage will be taken of lighting the power and car house at 
Rushcutter’s Bay by electricity. Arrangements have also been 
made by which the pumps in connection with the Double Bay 
low-level sewerage will be worked by electric motors driven off the 
Rose Bay Tramway.
