maintenance of the OHE at LPI is very difficult even during the nights

due to shunting and MMTS movement. Now Division has come up with
a solution for getting power by isolating all the individual lines at LPI, by
erecting the 4 new Sectioning insulators and isolators and by converting

UIOL to IOL at LPI yard.

With this modification, isolation of the individual lines becomes

easy and there by getting power blocks for OHE maintenance.
Moreover this modification increases the effective utilisation of
manpower by reducing the ideal setting of staff due to non-availability

of power block.

 Modification of OHE at 163 KM @ PDPL-NZB section:

State government has taken up the ROB work at 163 KM (LC-
3), OHE should be made dead for erecting girder and for bridge works
at the site. Same was done by creating temporary Section Insulator

neutral section by erecting four section insulators and one isolator at
Loc. 163/18, 19, 20 & 164/1.

 Modifications at BPA Yard:

The OHE of suspended goods line 7 was dismantled and securely
anchored at BPA yard. As the line was suspended long back, big trees

are proliferated, any tree falling on OHE will leads to major breakdown
as the suspended OHE is directly connected to main line.
