9. Battery Repair, Carriage Wiring, Air conditioning
Firstly went to the workshop 30 and there are 3 sections. Such as,
1. Battery section.
2. Air-condition section.
3. Wiring section
There are two types of batteries in train battery section Those are,
 Lead Acid based batteries
 Alkaline based batteries.
Training Experience

10. Battery maintenance procedure of Alkaline based battery
Alkaline Based Batteries

11.  Clean the terminals and battery surfaces of the battery
pack,
 Check the voltage and electrolyte level,
 Connect all batteries in series, full charge the battery
pack,
 Record current and voltage through the battery pack and
individual battery voltage, identify the condition of the
batteries,
 If their has a fault battery in battery pack remove it and
replace the new one.
 And Full charge the battery pack.
Lead Acid based batteries
Battery maintenance procedure of Lead Acid based batteries.

12. Air condition Section
Air condition section done by AC in train carriage and rooms in
railway.
Air conditioning is used to cool or remove heat from a space or
area. It has two parts.
1. Indoor Unit
2. Outdoor Unit
There are 4 parts in air-conditioning cycle.
• Evaporator (Indoor Unit)
• Expansion Valve (Outdoor Unit)
• Condenser (Outdoor Unit)
• Compressor (Outdoor Unit)

20. Making Battery Lugs

21.  The most important idea is to improve technical
skills.
 I learned about electrical, mechanical, casting,
machining, production processes, and metal
analysis processes.
 Having knowledge of lathe machine operation
is beneficial.
 Experienced in working with management and
company workers.
 The most important idea is to build teamwork
through activities.
Skills and knowledge gained…

22.  Motivating the workshop workers
 Improving employees to work on multi-tasking
 Giving enough rest
 Making a good working environment to workers
 Displaying the notice boards to raise awareness about the importance of wearing
PPE and the dangers and hazards.
 In order to increase the efficiency between the workshops, they are introduced on
new technical equipment and giving knowledge on how to use it.
 Giving technical training on all workers.
Suggestions

23.  In my university career, I received a good opportunity on working in
the Chief Mechanical Engineering Sub Department of the Sri Lanka
Railway Department. During this time, I obtained lots of experience in
mechanical and electrical engineering, as well as get a basic
understanding and learned new things about those two sectors.
 I worked with many people which have various ideas and abilities, and
I also joined repairing and maintenance services. During this time, I
practiced to works in an industrial atmosphere, and the theory I gained
at university assisted me in doing my best.
 During my training, I had the opportunity to attend 13 workshops. So I
could learn about how the work would be done in various workshops
independently.
Conclusion

24.  Prof. K.R. Koswattage The Dean Of The Faculty Of Technology Is
Grateful For Being Given This Opportunity.
 Dr N.P Liyanawaduge , Head of the Department Engineering
