INTRODUCTION
On the narrow gauge (762 mm gauge)sections of the Indian railways where permissible axle load is limited to 6t. To meet the requirements of these sections a locomotive ,N/ZDM5 class, B-B type, 450 HP, with axle load of 5.5t has been designed and built by CLW.
The power pack of this locomotive consists of kirloskar- cummins make diesel engine model KTA- 1150L, 6 cylinder, 4 stroke, turbocharged and cooled, set to deliver 450HP at 1900 rpm.

STRUCTURE OVERVIEW
Super structure of the locomotive is in three parts –
long hood- divided in three parts for easy assembly and removal. It accommodates power equipment and main auxiliaries like compressor and exhauster.
Drivers cabin – is sufficiently large and equips all controls , instruments and gauges.
Short hood – battery boxes and reservoirs are housed in this compartment .

Lubricating oil system
KTA 1150L diesel engines have forced feed lubricating oil system with low lubricating oil protection device .
The lube Oil system is four fold:- To lubricate all the moving parts in an engine
. To help in seal combustion chamber from the
crankcase. To clean the engine by picking up foreign
particles To cool the parts that it contacts.
