3. INNOVATIONS

Mechanization of Manual Loco Turn Table
WDG4 HHP diesel locos are provided with single driver cabin. During
MU, Driver cabin should be in leading position. Hence, the locos were
sent to KZJ chord line for turning the direction of loco (i.e. for driver
cabin in leading position). Due to traffic constraints, turning of loco

used to take more time and also wastage of crew.
Hence, Loco turn table was sanctioned under Augmentation works of
100 locos to 150 locos vide PB no – 615/15-16. The same is constructed
and completed on July-19 at a sanctioned cost of Rs 69,66,223/-.
But the above turn table has to be rotated manually after placement
of locomotive. This involved requirement of huge man power i.e. 10 to
12 man power are utilised to rotate the turn table and was strenuous in
nature.
Hence, the manual transmission was converted into motorised
transmission with in-house resources as detailed below:
1) Gear box with DC motor of old condemned Jumbo trolley was
removed and utilised duly overhauling the same in-house.
2) An arrangement was developed and manufactured in-house to

couple the gear box along with motor to manual transmission.
3) The supply to DC motor is given by use of 04 nos of loco batteries
and these batteries are charged utilising an external battery charging
unit.
4) Required control equipment is assembled in-house and necessary
contactors are provided to rotate the turn table in either direction i.e.
clockwise and anti-clockwise direction.
5) Approximately an amount of Rs 7,500/- was incurred on providing
the motorised arrangement for the manual arrangement of turn table.
6) This has resulted in savings of approximately Rs 2.5 to 3 lakhs for

provision of new motorised arrangement apart from saving the man
power that is utilised to rotate the turn table.
