Precautions to Prevent Stalling
Ensure Before Starting
•
Load is permitted as per WTT for the section/class
of loco
•
No brake binding
•
No TMs/FIPs are in isolated position
•
ECS in MU trailing loco is in run position
•
Both loco LAM is responding in case of MU
•
No adverse remark in the repair book regarding
hauling power
•
Sand gears are in working condition
•
Sand box filled with
filtered & dry sand
•
Spare sand bags are available
•
TE Limit Switch & Power Setter switch is in
proper position
While approaching steep
ascending gradient
•
Keep the train at attacking speed at the bottom of
the gradient
•
Release the DB as well as train brakes well in
advance by which train will roll free
•
Open few notches before entering up-gradient and
open notches as early as possible with sufficient pause in between notches to
avoid sudden stretching
•
When speed is reducing due to gradient, do manual
sanding when adhesion is less till gains speed above 20 KMPH (Do not wait for
wheel slip to occur & auto sanding)
•
In microprocessor loco if still wheel slip
experiences, do not reduce the notches & continue manual sanding till train
coming to stand still/sever jolt is experiencing.
•
If a speed restriction is there, avoid A9/DB
application and try to observe speed restriction by throttle manipulation
•
In non microprocessor loco if still wheel slip
experiences, reduce one notch & continue manual sanding.
•
If a speed restriction is there on the steep
ascending gradient, avoid A9/DB application and try to observe speed
restriction by throttle manipulation
Stopping on ascending
gradient
•
Try to stop the train by throttle manipulation,
avoid A9 application (Apply A9 where
ever required with one or two notches in open position)
•
Before coming to dead stop apply manual sanding in
such a way that loco stopping over sand to increase adhesion during rain
Restarting on ascending
gradient
•
Open sufficient notches to build up power to hang
train
•
Release A9, wait for brakes are fully released,
•
Take one more notch, start manual sanding
•
Release loco brake. (Do not release Loco brake fully
till train started rolling ahead in case of HHP locos)
•
Continue manual sanding till speed picks up (20
KMPH)
•
In microprocessor loco if still wheel slip
experiences, do not reduce the notches & continue manual sanding till train
coming to stand still/sever jolt is experiencing
•
In non microprocessor loco if still wheel slip
experiences, reduce one notch & continue manual sanding.
•
Open notch by notch with sufficient pause in between
by observing load meter
