greater seating
capacity than the horse car can be constructed on a different plan for
the price given for the electric car. This price, it must be noted, is
the one for attachment of motor to the present horse car. The horse
cars produced to-day are most carefully planned, thoroughly built, and
admirably adapted to their service, but the inexorable law of progress
decrees their extinction, for something better.
Motive power. To represent clearly the costs, etc., of the three
systems under this head, let us assume a road. Take, if you please, a
double line 6 miles long, and operating 24 cars with speed of 6 miles
an hour, and running 20 hours out of 24. This would call for 48 horses
on the track and 192 horses in the stables, or a total of 240 horses;
at $160, counting harness, etc., this would cost $38,400.
With electricity we will proceed as follows: The weight of car with 30
passengers and motor attachments would be about 9,000 lb. It is easily
calculated that to propel the same at the specified rate on a level
would take about 1.
