3. PROBLEM STATEMENT
 Design a platform which can accommodate one
locomotive, and be able to allow personnel to
perform maintenance inside and on the body of
the locomotive, without height/ elevation
interference.

7. PURPOSE AND VALUE OF
THE STUDY
 Increase maintenance time efficiency.
 It will provide walkway and workspace.
 Easy access to remove and install the
covers and accommodate them.
 Reduce effort of heavy lifting.
 Prevent accidents/ insistences (falling).
 Easy access to the front and roof for
maintenance.
 Provide safe and friendly working
conditions.
 Grading will decrease any slippery.

8. Methodology
 Carefully analyze the workshop layout and
take measurements where necessary.
 Analyze the fleet (locomotive) that will be
using the platform.
 What will be the maximum weight that the
platform should carry (working safe load).
 Gather information.
 Designing of joining method.
 Make a rough sketch of an ideal platform
judging from the analyzing of both the fleet
and the workshop layout.

9. Methodology cont.
Academic knowledge
 Strength of material
 Stress analysis
 Mechanical engineering design
Software
 finite element analysis
 CAD (Creo)
 MathCAD
 Microsoft
