    Study Notes

    Rail Temperature

    • The range of td or t0 shall be within the limits of rail temperature, which is categorized into four temperature zones (I, II, III, and IV) with corresponding rail sections and temperature ranges.

    Installation Temperature (ti)

    • The average rail temperature during the process of fastening the rails to the sleepers at the time of installation of SWR/LWR/CWR.

    Mean Annual Rail Temperature (tm)

    • The average of the maximum and minimum rail temperature recorded during the year, which can be fixed locally based on rail temperature records or read from the rail temperature map.

    Prevailing Rail Temperature (tp)

    • The rail temperature prevailing at the time when any operation connected with LWR, such as de-stressing, is carried out.

    Stress-Free Temperature (t0)

    • The temperature of Rail in LWR/CWR at which the rail is free of thermal stresses.

    Rail Tensor

    • A hydraulic or mechanical device used for stretching the rail physically.

    Rate of Change of Cant or Rate of Change of Cant Deficiency

    • The rate at which Cant or Cant deficiency is increased or reduced per second, at the maximum permissible speed of the vehicle passing over the transition curve.

    Sand Hump

    • A sanded track that works as an isolation, provided after loop lines to avert collision with main line vehicles.

    Duties of Permanent Way Officials

    Assistant Divisional Engineer (ADEN)

    • Responsible for the inspection, maintenance, and safety of all way and works, including bridges, in the sub-division.
    • Should have knowledge of Rules and Regulations, including the Indian Railways Act, Indian Railways (Open Lines) General Rules and Subsidiary Rules, and various manuals.

    Inspection and Patrolling

    • ADEN should inspect and patrol the track and bridges regularly, including:
      • Channel sleepers once a year along with bridge inspection
      • AT welding site at least once a month
      • USFD Test check monthly
      • Monsoon Patrolling when introduced
      • Hot Weather Patrolling when introduced
      • Night footplate inspection once a month
      • Side drains, catch water drains, and bridge waterways once a year before the onset of monsoon
      • Accompanying TRC/OMS Run
      • Small track machines once in three months
      • Work of other organizations like RVNL, DFCCIL, Construction, etc.

    Gang Mate's Responsibilities

    • To maintain additional/special equipment in good condition and report any defective equipment to JE/SSE/P.Way.
    • To introduce hot/cold weather patrolling when instructed by supervisors.
    • To be vigilant during hot weather and order patrol if the temperature is likely to reach td+20°C.
    • To take prompt action to protect the track in case of rail/weld fractures and carry out emergency repairs.
    • To take immediate steps to secure the safety of trains if they consider the track is likely to be rendered unsafe.
    • To report any ballast deficiency or disturbance of the track to JE/SSE/P.Way.
    • To inspect SEJ and LWR/CWR frequently, especially during the hottest part of the afternoons in summer.
    • To note down the details of missing fittings and fastenings and recoup them as soon as possible.
    • To note down the details of cracked/broken/notched sleepers in the track and advise the same to JE/SSE/P.Way.
