The Railway Signaling system works with
the following aims in mind
1)
Run trains with safely.
2)
Run trains efficiently
3)
Even during failures safety
features are maintained
4)
Multiple levels of checking
exists
Railway
signaling systems use various technologies from the traditional
Mechanical engineering to the latest Electronic Engineering.
The use of electronics in
Railway signaling has been slower than the introduction of
electronics in many other areas. The reason behind the same has
been due to the following reasons
Reliability
of electronic components in uncontrolled environment had
improved to proper standards only about 1980 s
The
failure modes of electronic components are many more than
that of mechanical or electromechanical components
The
development of electronics was at a time when the Railway
system had lost its commanding position as means of
transport and many Railways are not economically
viable.
The
Railway operations being based on very old methods do not
attach very high importance to efficiency and therefore
the need of electronics that is related to efficiency to
a great deal lose its significance compared to other
traditional technologies.
However
the Railway signaling system is gradually turning towards the use
of electronic technology more and more as electronics is
becoming reliable and also economical even for Railway systems
not in economically healthy condition. For more information.
The main philosophy on which
the Railway signaling systems are being designed is the use of
multiple checking to see that no safety aspect is left dependent
on only one proper working of only one component of the system.
