ANNUAL ADDRESS. XXV. 
electric tramway, but generally speaking the electric is more 
economical than the cable. 
In Chicago, where there is an excellent cable as well as an 
electric service, the cost per car mile was fivepence with the 
cable, as against eightpence with the electric, but the receipts 
were tenpence with the cable: against seventeenpence with the 
electric. Hence the profits derived from electric traction are 
much greater in Chicago than with cable traction. 
In Sydney if the work of converting our present system of 
tramways is done as well as we have a right to expect it to be, 
we shall have no reason to regret the change financially. In 
every other respect the result is likely to be beneficial, and I wish 
the Railway Commissioners every success in their endeavours to 
Provide a complete system of electric tramways which will meet the 
wants of Sydney. 
Electric Locomotives.—The largest electric locomotive yet con- 
structed in America is that which is used for working the 
Baltimore Belt Line, which consists largely of tunnels. Electricity 
Was adopted in this case to avoid fouling the tunnels with smoke 
and burnt gases. This involved the construction of three ninety- 
five ton locomotives, each capable of hauling a five hundred ton 
Passenger train at thirty miles an hour or a 1,200 ton freight 
train at fifteen miles an hour on a gradient of one in one hundred 
and twenty-five. The locomotives are now in actual service, and 
are working in a satisfactory manner ; they will exert a draw-bar 
pull of 42,000 pounds continuously, or 60,000 pounds at starting, 
and they are said to be capable of developing 1,400 H.P. 
I saw the large electric locomotive constructed by the Westing- 
house and Baldwin Locomotive Company standing in the Baldwin 
Works, Philadelphia, and during my visit to the General Electrical 
Company’s Works at Schenecktady, I saw a still more powerful 
locomotive in course of construction, with larger driving wheels 
for higher speed. So far however, it appears that while electric 
traction may be used with economical results in street and
