ØUnmanning of TSS:

Two TSSs of Nagpur Division Nainpur/TSS(in G-JBP line from14.06.21) and Nagbhir/TSS (in G-BPQ line from 06.07.21) has been unmanned during day time (P2 & P3 shift). One staff is booked only in night duty (P1) from 00:00 Hrs. to 08:00 Hrs. By this arrangement there is huge saving in the manpower and revenue.

ØContact wire height adjustment for passing of Oxygen Special Train:

Over Nagpur Division, contact wire height adjusted at 47 locations for the smooth passing of Oxygen Special Trains (ODC) at vulnerable locations where contact wire height was less.

ØProvision of Tower Car for newly Opened Depot at CWA & GRG:

New 8 Wheeler Tower Cars have been provided to newly opened OHE-PSI Depot at GRG (under G-JBP line) and CWA (under CWA-ITR line) for carrying out day to day maintenance and breakdown attention.

ØParallel Operation of Traction Transformers at KWN/TSS :

·Feeding zone of Kachewani TSS is from KWN to TMR/SP i.e. 23 Km towards NGP side & KWN to G/SP i.e. 26 Km. towards BSP side i.e. total feeding zone is 49 Km. in main line. In addition to main line, KWN/TSS is also feeding up to SNV/SP via FCBs of HDM/TSS (Total 75 Kms.) in G-BPQ section. Feed of KWN/TSS in G-BPQ section has been extended to minimize the feeding zone of Naghbir/TSS up to SNV/SP as Gonglee-Hirdamali & Gonglee-Sondad having rising gradient of 1 in 100, it became crucial for train operation due to frequent voltage fluctuation which had caused stalling & time loss of trains in the past.

·There are two Transformers of capacity 13.5/20 MVA each of MINEL make are available at KWN/TSS. As per standard practice single transformer was in service, which was not catering the additional load enhancement, resulting there were avg. 10 overload tripping per month. To meet the additional power requirement, parallel operation of two Power Transformers was introduced.

·Further after obtaining technical approval from HQ, parallel operation of Transformers has been initiated from 17.06.2021 onwards which is running successfully since its commission.
