In handling material with supply cars there is the follow-
ing saving: No delays to trains on account of the train crews
stepping at each point during the month to handle thousands
of articles needed along the line. No waste labor in packing ma-
terial. No labor expended in hilling thensands of articles that
are handled from the supply trains. No cars destroyed for ship-
pers by having oil spiled in them. No billing or shipping back
of empty containers to the store. No pilfering of material. No
loss from breakage. No claims or correspondence regarding
shortages.
One of the greatest advantages of the supply cars is the fact
that we are able to carry out the exchange arrangement ve-
garding station supplies, signal supplies, track tools and sup-
plies. This can be accomplished m no other way.
BY 1. D. GENEST, CANADIAN PACIFIC.
On the Canadian Pacific western lines eight cars are operated
as separate units and patrol 7,500 miles at stated monthly inter-
vals. They are equipped and directed by four divisional store-
keepers with a storeman in charge of each car. Deliveries are
confined to light supplies and tools such as are required for
maintenance purposes for stations, sections, water supply, etc.
Requisitions from each of the sixteen sub-divisions are sent to
each of the respective divisional storekeepers not later than the
twenty-second of the month for the following month's require-
ments, and are fastened separately in station order for each de-
partment and each section or branch, as the case may be, to
enable a check to be made in the superintendent's office to in-
sure receipt of all requisitions. The stoneman in charge of the car
wires the superintendent a day or so in advance stating the sub-
division of his district the car will cover so that all concerned
may be advised to have their oil cans and old material in readi-
ness for the arrival of the car.
DISCUSSION,
The carrying of handy workmen on the supply train: w do
small work, such as litcing window glass, repairing locks and
hinges, etc., on buildings and other structures along de road,
had been found most satisfactory.
THE AUTHORIZED LIST
BY E. J. MYEIGH, GRAND TRUNK.
The meaning of this is that we have on out railways a list of
all the items of material we use; this list to be most carefully
compiled, and finally approved by our president and his vice-
presidents. This looks like a large order, and it is, hat it can
be done. This list establishes our standards as they have never
before been established. It gives them the stamp of approval,
and in getting it up our people will make such a study of the
supply question as they have never made before in the history of
railroading. With this list in working ordet each department
will know what they can and should ask for. Each storekeeper
will know what he can and should have in stock. Any departure
from the list will be cause for inquiry. Fach inquiry will help
to guard our standards and preven: increasing our items. The
increasing of our items means the increasing of our stocks on
hand,
The association should appoint a commitice to look into this
question and report, and further, each member of the association
should take the matter into careful consideration, and assist the
committee by giving them the bene of his views.

STUMPF LOCOMOTIVE CYLINDER
A locomotive on the North Eastern Railway of England has

The uni-flow system of steam distribution. This was briefly ex-
plained in the discussion of the paper on "Factors in the Selec-
tion of Locomotives," presented at the Railway Session of the
American Society of Mechanical Engineers last December. In
consists chiefly of an arrangement of special valves, pistons and
passages so as to avoid any return or backward motion of the
steam after entering the eshnder, Its use regmres cylinders of
a length nearly equal to twice the stroke and with stea admis-
sien ports at either end in the ordinary manner and special ex-
haust ports at the center. The piston is a large hallow casting
of a length practically equal to the stroke of the locomotive. The
valve controls only she admission and point of cut-off of the
stean and the exhaust is controlled by the piston which opens
the exhaust passages at the center of the cylinder as it reaches
the end of its stroke.

on the North Eastern Railway is shown in the illustration which
is taken from the Ratheny Gazette of London.
Experiments on the continem with this type of Incomotive
have indicated that it possesses considerable economical arivant-
age as regards steam consumption. In fact, it is claimed that
it is superior to the usual superlicater locomotive. This increase
ei economy is apparently due to the fact that the cylinder walls
and the piston head are not cooled as much by the outgoing
steam as when the steam is exhausted through the same pas-
sages through: which it enters. Furthermore the exhaust passage
can be made larger and the steam is released much more
promptly.
When working at full stroke, as is the case in starting, the
valves are so arranged that they add to the exhaust passage and
allow a small portion of the steams to escape through the ad-
mission passages. This action, however, only takes place when
working at practically full stroke.
STATION PLATFORM CHARGES IN ENGLAND, The London &
Northwestern now makes a charge of one penny for admission
to train platforms at Waterloo Station, Lundun.
