ADVANTAGES OF SSI
The major advantages of commissioning of HRS SSI can be divided in the
following parts:-
Safety Benefits
Manpower saving
Operational Benefits
Maintenance Benefits
1. Safety Benefits
Removal of worn out lever frames and mechanical rodding.
After commissioning of SSI, existing East & West Cabins and SM
Slide Frame will be removed completely and all the operations shall bedone from the LCPs provided in the ASM room of HRS station.
After SSI complete yard and all the running will be DC track circuited
from Home to Home. Presently Hathras Qila side branch line, line no 5
and 6 are non- track circuited.
2. Manpower saving
Complete elimination of operation from the East and West cabins will
result in saving of manpower involved in operation at these cabins
round the clock.

machines in place of old & worn out rod operated mechanical points.
Replacement of steel/wooden turnouts by PRC turnouts having better
reliability of points.
Maintenance PC/Data logger for the entire system facilitating
predictive maintenance & monitoring.
Provision of Stabilised power supply in 1+1 configuration through IPS,
having 100% standby.Provision of glued joints for track circuiting.
2. Engg DepartmentReplacement of steel/wooden turnouts by PRC turnouts having betterreliability.
3. TRD Department
Change in sub section plan of OHE of the yard having more flexibility
from operation and maintenance point of view.
