Respected Sir,
In
the recent past, there were 11 SPAD cases occurred in TVC division. It may be
worth noticing that each of these SPAD on account of passing the departure
signal, i.e. the starter, and in all these incidents the train is scheduled to
run through the station, but signaled to stop at the station out of course.
This peculiarity or the identical circumstances made us to investigate the
cause. All are in agreement that no Loco Pilot shall intentionally pass a
signal at ON. An error in judgments, or
on some confusion, or over confidence on brake may be the reason to commit a
SPAD.
The age old signal
combination has been changed, and that the changes were effected first in TVC
division, that too station by station on a gradual manner. While changes started to effect, some
stations have the old signal combination and in some new combination of
signal. Moreover the changes have been
completed in a span of 16 months.
Before the introduction
of the new combination of signal, if the distant signal shows Proceed aspect,
that convey a clear message to the crew that the train is being received on
Main line and the aspect of next signal – the Home signal – either Proceed or
Caution. In this combination of signal,
the crew is very keen to observe the first signal – the Distant signal - and
again the crew is very keen to observe the home signal whether it is caution or
proceed aspect. When the Home signal
shows proceed aspect, the crew normally will not be so keen, as in the case of distant
and home, in observing the dispatch signals thus the departure signal in a way
seems to the crew an insignificant one.

In the new combination of signals, it
seems that the Home signal in the mind of crew become insignificant like the
departure signal. Now in the new system the Distant signal shows Proceed
aspect, convey the meaning that all other signals of the station is cleared,
thus the Home signal as well as Starter / Advance starter in a way become
insignificant in the mind of the crew.
They will not be as keen about the Home signal as they used to be in the
older system.
When the train is scheduled to run
through, the crew normally will be in a state of mind that the signals –the
Distant, Home and departure signals will be in his favour. This perception only change when they
encounter the signal of the station in the old and new system. In both the
systems if the distant signals shows caution aspect the crew will very keen to
watch the aspect of the Home signal and on the process to stop at Home signal.
Regarding the attention aspect, in the old system it gives a definite meaning
that the train is going to be received on Loop line, accordingly Crew shall
regulate the speed so as to enter the points at 15/30 kmph speed. Where as in the new system if Distant shows
‘Attention’ aspect, it will not give a definite meaning as in the old system –
it may be received either on Main line or Loop line. This gives a lot of
confusion to the crew, whether to reduce the speed to 15 kmph or not.
When the crew observes the most
restrictive aspect of the Distant signal, i.e., Caution aspect, they will be
very alert and keen to stop at the next signal.
But when the distant signal is observed as taken OFF, they become not so
keen to observe the Home signal aspect, combined with effect of the Home signal
getting insignificant in their mind with the introduction of new system, it is
likely that they may momentarily forget the aspect of the Distant signal which
they have observed earlier. This disturbed perception and interpretation of the
indication of the signals, and confusion created owing to the introduction of
the new system is, we think, the one of the underlying causes for these
incidents.
We are not intend to defend, but examining
the reasons for the sudden spurt of identical type of SPAD in TVC division, in
the backdrop of the introduction of the new changes made, for the first time,
with regard to the signal indication system. We too agree that some positive
aspects are there in the new combination of signal aspect, but some unforeseen
aspect also lies. When a new system of
combination of signals is being introduced, there will normally erupt some
wrong concepts, confusions etc, in the mind of the crew, during the transition
period.
In TVC division most of signals –
especially Home signals situated after a curve, where visibility is restricted
to 300 to 400 meters, but in SA, PGT and MAS area the Home signal is visible
either from distant signal or from a distance of 600 to 800 meters in
advance. In 60% of the stations in
between the Distant and Home signals there is atleast one Gate signal is
provided in TVC division. The visibility
of the Home signal starts only after passing the Gate signal and not from the
Distant signal. In some stations,
according to SWR, first take off the Gate signal that means if the Gate signal
is taken ‘OFF’ the Home signal is in ‘OFF’ aspect. In some other stations it is in the reverse,
that ‘OFF’ aspect of the Gate signal never gives an assurance that Home signal
also be taken ‘OFF’. It may specially
noted that most of the stations, the Home signal can be visible after passing
the Gate signal.
On enquiring with the S&T department
it is come to understand that, where the distance between Gate signal and Home
signal is lesser than 400 meters,
without first taking ‘OFF’ Home signal, Gate signal cannot assume ‘OFF’
aspect. Where the distance is more than
400 meters, the Gate signal and Home signal works as independent signals. ‘OFF’ aspect of Gate signal not

give
an indication that Home signal also be taken ‘OFF’. This two types of signal combination is
vulnerable to mistaking. And the whole concept
is wrong. The criteria of 400 meters
must be reckoned from where it is visible, not the actual distance between
signals. This creates a lot of confusion
in the mind of crew that in which station what combination exist. Therefore an identical combination be derived
atleast where the Home signal could not visible before passing the Gate signal.
We
are not advocating to switch over to old system of combination of signal
aspect, but plead that these SPAD cases occurred in the transition period from old
to new system, combined with the special position of terrain in TVC division. We
also see that in other divisions such as PGT and SA where the same TVC crew
works there have not any such SPAD. In
this connection it is our opinion that the terrain and visibility position in
TVC division and the introduction of the new signal combination has a bearing
on the SPAD.
Regarding the terrain, the peculiarity of
the TVC division with undulating section throughout the division is a unique
feature. The risk of over speeding or losing punctuality if run below MPS
always exits due to this undulating section. However, with the great deal of
importance being attached to punctual running of trains and statistics being
monitored on various causes leading to loss of punctuality the Loco Pilots are
compelled to keep the MPS. In addition, the Loco Pilots encounters more number
of signals in danger aspects while working in TVC division, more number of out
of course stopping, more stopping stations etc. This sensitive condition put
the LP in a crisis and the thought of risk always linger in the mind of the LP
thus sometime negatively affecting the absolute concentration needed to be
maintained while approaching the signal. The fact that SPAD occurs
predominantly in the express train working underscore this effect.
Regarding the visibility, the difference
in TVC division compared to other divisions is that the sighting distance of
most of the signals are very less or minimum due to curves or other
obstructions and the situation that the LPs are not able to see the related
signals together at the same time also contribute negatively. In addition to
this, the unmindful and frequent changes being made in the signal sequence and
location of the signals, as against what ingrained in the minds of the LPs
through experience, in TVC division in the recent period created a sense of
uncertainty and confusion in the place of the confidence they once used to have
regarding signals. Even there has been occasions
when LP suddenly come across a new signal in the section, find no signal in the
expected location without any notice issued to the Crew as required in GRS. We
can point out numerous incidents in this connection if solicited.
We plead before your esteemed office to
view the SPAD cases in TVC in this context too.
Do not dump the crew of TVC as bad.
It may be noted that the very same TVC crew working through PGT and SA
divisions are not committing any SPAD in those section. There are many intriguing factors lies behind
a SPAD, not the alertness alone.

Throwing them out of service on CR even in
appeal, and reduction to a lower post / pay for a long period such as 21 years
or until retirement is too harsh and destroying not only the employee but also
the poor family. Destined to suffer for whole life is something which is
unheard of, and it shocks the consciences of many. We plead that a sympathetic consideration be
extended. In the long run the new system will instill the correct perception in
the minds of crew. Transition period is
a vulnerable period, and mistakes in this period may be viewed leniently.
It seems that the trend not to allow those
involved in SPAD to continue in running duty for the whole service is
unwarranted and based on fear psychosis.
If such a decision is against a habitual offender, it will sound
well. It may please be noted that in
almost all cases, the Loco Pilot who committed a SPAD has 20 to 25 years of
excellent record in running duty.
Succumbing to a human error once in such a long service should not be
construed like a habitual offend and the employee should not be barred forever.
The experience and record show that nobody reinstated in running duty after
SPAD has ever repeated the mistake thereafter. It is also on record that many
of these who involved in SPAD were considered as best Loco Pilots having very
good track record and graded as ‘A’ for many years.
Yes, there is clear instruction that an
ALP should apply the emergency brake when he thinks that the train will pass
the signal at ‘ON’. Does it mean that by
application of Emergency brake the train should stop short of signal? Practically it is not possible. If the Loco Pilot is not braking at all when
the train approaches the signal which is at ‘ON’ it is a different case. In every SPAD case, your good self should see
that the Loco Pilot has applied the brake while approaching the said signal and
the ALP naturally expect, up to the last moment, that the train will stop short
of the signal. If the ALP tends to apply ‘Emergency brake’ on mere suspicion,
that the Loco Pilot could not stop short of the signal, total chaos in the
Railways will be the result.
An ALP cannot asses the braking skill of
individual Loco Pilot, this skill will differ from one LP to another. Therefore, the way each Loco Pilot apply
brake may vary. The ALP could realize
that the train will pass the signal at ON, only when it becomes definite at the
last moment and what best he can do is to reduce the distance travelled past
the signal. This is the fact and
reality. Throwing him out, even though
he applied ‘Emergency brake’ in SPAD case is something we could not understand
at all.
In
the back drop awarding inhuman punishment to Crew, the TVC Divisional Committee
of AILRSA decided to show their anguish, in the process they organize a
‘Dharna’ in front of the DRM office along with their family on and silence the staff for 5 minutes on 31.03.2015
between 08.00 Hrs and 08.05 Hrs.
With regards, Yours
faithfully,
