Q: The Chicago. Milwaukee & St
Paul Railroad has electrified its
lines which run through the Rock,
Mountains. We have heard 1t said
that the motors which drive the en-.
gines up the grade on one side Of
the divide act as generators while
the load Is being taken down the
other side. AS q result of the ar
rangement the train while descend
ing either will generate more than
enough electricity to make up for
what II required to pull the same
load up the opposite side. We
would like TO know the facts in the
case. r. N. A.
A. The electric locomotives used
are equipped with what is known as
the regeneration feature: that is
| they are SO arranged that on coast
/ ing grade the motors may be run as
generators and due to the force OF
| gravity electric power is returned to
the trolley line. The amount OF
energy which returned to the line
during regeneration as compared
with the amount of energy required
for motoring the same train depends
both on the train tonnage and or
the steepness of the grade. Assam
ing per cent grade and a train
corresponding to: the continuous ca
pacity of the locomotive the amount
of energy returned to the line, run
ming over given length OF the
per cent grade, Is about so per cent
Of that required to haul the same
train over the same length of 2 pei

on a 2 per cent grade the locomotive

train to overcome the grade aac
must exert an additional pounds pei
ton to overcome the train friction
making IS pounds per ton total. In
going down the grade the gravity
pulls at the rate of 10 pounds per
ton, but is opposed by the friction oil
6 pounds per ton so that "a pounds
per ton is regenerated over a Eiver
distance as compared with As pound:
! per ton being required to haul the
train.
