• First locomotive rolled out in 1964.

• DLW is only manufacture of electric-diesel locomotives with ALCO.

• DLW got its first ISO certification in 1997.

• DLW exports their engines in SRILANKA,BANGLADESH and many more countries in Asia.

HEAVY MAVHINE SHOP

1. CMT LAB:-

• It is known as a chemical metallurgy lab.

• Qualitative inspection of raw materials which is purchased from outside and which should be manufactured in the workshop.

• Chemical analysis of ferrous and non ferrous materials.

• Metallurgical analysis of defective components.

2. PIPE SHOP:-

• Pipes are manufactured in the workshop for passing a fuels in the engine.

• They are also used in the engine for compressing the air to apply the breaks.

• Pipes are dipped into the solution i.e. hydrochloric acid(HCl) by which in the future having no rust on the pipes.

• It should also coated by the special polymer paint which should also help to away from the rusting.

3. HEAVY MACHINE SHOP:-

• Lathe Machine: The lathe is used for producing cylindrical work..

• Shaper Machine: Shaper is a machine used for the production of flat surfaces in vertical, horizontal planes.

• Drilling Machine: A machine designed to hold drill bits which will produce cylindrical holes.

• Milling Machine :A milling machine uses a rotating tool to produce flat surfaces. A very flexible, light-duty machine.

• Grinding Machine : Used when a close tolerance and very smooth finishes are required .

HEAVY MACHINE SHOP:-

CNC LATHE MACHINE:-

• It is known as a computerized numerical controlled machine.

• It should be highly based on the CAD or a CAM program.

• Its motion should be along the multiple axis and at least about the two axis i.e. x and y axis.

-:TYPES OF TESTING:-

Lubricating oil testing:-

• Lubrication is done for the better performance of the engine parts.

• Testing is done by the checking of circulation of lubricant oil.

• Checking also for the returning path of the lubricant oil not only for the forward path.

• RR40 is used as a lubricant oil.

Water testing:-

• Water act as a coolant for moving part of the engine because constant rotation or movement cause various parts to heat up and water working as a coolant.

Load testing:-

• For load testing electrical load is provided for the testing. If there is any abnormal sound in the engine then it should be again tested for the lubrication and if there is any flaw in it should be removed.
