branch is seven, both covering the ter
| ritory which lies in the northwest OF
Milford.
Hopedale is but trihe over mile
from Milford but from the standpoint
of traffic, is town of considerable i'm
portance, being the home of one of the
largest machine industries in the coun-
| try. that of the Draper Company. Hope
| dale and Uxbridge have been con-
| nected during the past year, by extern
sions made on the southwest, North
| Grafton at the northwest, and Hopkin-
J ton. on the north, have also been
! brought within the ban of the Milford,
Holliston & birmingham system and
these lines, as they stand completed.
will more than double the mileage of
the outfit, compared with that operat-
ed a year ago. The branch line, from
Milford to UXbridge, is to be operated
by separate company, known as the
Milford & UXbridge Street Railway
Company. The same financial man
agement controls it, however. and the
road has practically the same set of
officers.
At the present time, the branch line
to North Grafton, an identification Of
an old steam railroad, the Grafton &
Upton. is operated by steam, but the
electrical equipment of this line has
progressed very rapidly during the past
few weeks. and the road will be oper-
ated as a trolley system early next
year. Inside of another month the en-
tire system of the company will be
running by electricity The power for
the entire system is furnished at the
plant of the company in Milford, this
not only supplying the currents of the
street railway but for the lighting cir
cults of the town. The business of
lighting, however, is controlled by the
Milford Electric Light & Power Com
pany which takes control at the
switch board at the power station in
Milford and attends to- the matter Of
selling and distributing the current in
Milford and Hopedale
The installation of new generating
machinery has made necessary the en-
largement of the power station, and
this work in itself is a notable feature
of the business energy which is being
shown. At the present time, the equip
ment includes four return tubular boil
ers and one somewhat similar in type,
all of which are of 150-hOrse-p ca
pacity. At the station, there has been
/ space enough reserved for four more
( boilers of the same type, but no more
power Of this kind will be needed FOR a
| time. at least. In the lighting portion
of the plant, there are two 2OO-horse-
power engines, belted to two 125-kilo-
wat alternators, these generators rum
ming at 1000 revolutions per minute and
/ giving a current of 2400 volts and %
! cycles a second There is separate
switch board which is used for the
! lighting circuits and this has posi-
ton some distance away from the rail-
way board. -,
The station supplies about $50 kill
owats for lighting, the lighting OF
streets in the town being by arc ana
| incandescent lamps. There are ABOUT
| sixty arc lamps and they are operated
| on a constant current circuit, rs IL
! kilowat constant circuit general cleo
/ trio transferrer being in position at
| the power station The lamps have a
voltage of 70 each. The power for the
| street railway work is furnished at the
| present time by two general electric
| six-poIe 600-volt railway generators
which are of 225 kilowat and 325 kilo-
wat capacity, both running at speed
| of 100 revolutions per minute. Ihey
| are direct, connected to engines which
! are operated condensing. In the ex-
| tension now being built, there is TO be
| erected. a 600-kilowat Westinghouse
railway generator, directly connected
| to a cross compound engine which will
run at 100 revolutions per minute and
| be equipped with vertical type con-
| densers.
The power station receives its water
! for both condensing and boiler feed
| ing. from a cistern at the edge OF a
| pond nearby, and connected with this
| there is a provision made for the re-
moval of all mud before water reaches
the boiler. Even-fow water tube
heaters are used for this purpose and
the company uses an apparatus that
is especially designed for its own case
/ Two such heaters are thus far in
| stalled. but another is to be placed In
I position with the new engine. There
are to be three sub-stations when the
enlarged system is opened. Two of these
are already in process of erection, one
| Of which is a storage battery sub-sta-
ton at Lake Mendon Park and the
| other a rotary converter station, To-
Gated in Grafton. The one at ORATOR
is to contain $50 kilowat Westing-
, house rotary converter, counterpart
Of one which is to be placed in posi-
ton at the power station in Milford
This rotary is being placed in the
! Grafton and Upton railroad depot II
Grafton. The capacity of the storage
battery plant at Lake MendOn will be
240 amps. The cells used in the plant
at Mendon are to be chloride accumu-
lators, placed in a separate wooden
/ building, erected for the purpose. A
| storage battery sub-station, of the
! same capacity, is already in use al
East Holliston. At this station, there
are 81 cells of the same make installed
each containing 10 plates, with oppor-
tunity to increase the capacity OF the
battery considerably.
A high-tension transmission line, be-
tween the power station at Milford anC
the sub-station at Grafton is to be used
in the operation Of the branch line tC
| North Grafton, this consisting of alu-
minum wires, strung on the regular
trolley poles. The transmission is Il
be made by a three-phase 10.000-voli
circuit and besides these, there is tC
be a $50 000-circuit mills aluminium
l feeder, for direct current distribution
It is expected that this aluminium
[ feeder, viii. with the aid of the sub
station at Grafton, be fully able tC
/ supply the trolley wire Of the ORATOR
| branch with the necessary current
The electrical equipment Of the old
| Grafton & Upton Railroad was start
I ed and a great deal Of work has been
done under circumstances that are pc
culiar enough. Its equipment has been
very largely done during the past few
weeks, in a manner which has not in
