Job Profile of SSE/signal is to supervise the maintenance of Railway Signalling installation. At present all important routes are electrified, hence Signals are controlled through a centralised cabin. The system is called Relay Interlocking or Solid State Interlocking.
SSE/signal Depot is headed by seniormost SSE. Under his control there are 1 or 2 SSEs and 3–4 JEs. Some 20- 25 Technicians and 50–60 helpers are also there to run the section given to Depot.
In real meaning the duty of Signalling department is tough, whether he is Technician or JE or SSE. In addition to day duty, Technician, JE and SSE have to go to attend night failures of signals. Rainy season is the worst season for Signalling department. Signal failures occur due to mistakes of other departments also, but you have to go and rectify it, as trains suffer detention due to it. I am not discouraging, telling only facts. I have got 39 years of experience in this specific field. I can write a full book on my sweet and bitter experiences.
One thing you should know in Railways Technical Supervisors of every department comes in the ‘EXCLUDED’ category as per ‘Hours of Employment Regulations’. Excluded means no rigid working hours. You are always on duty. You can adjust your working hours as per your convenience and department’s requirement.
I would suggest, If selection is there between SSE/signal or SSE/Telecommunications, you select SSE/Tele. Both posts are of same ‘S&T’ Department, officers are common. But service conditions are comparatively better for SSE/Tele.
