*********** What is Complete Redundancy In WAP-5 Locomotive ? ********
#railwayengineering
In the Attached Screenshot in Point 7 of "Targets for the month of April’16" of Position of projects being executed by C-D&D at CLW the following Sentence is written:
7. Complete redundancy on one more WAP-5 locomotive 30096.
Now...
more... can anybody explain what does the Term "Complete Redundancy" means for WAP-5 Locomotive ?

For Reference
As per Engineering Jargon "REDUNDANCY" means the Following:
In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe.
In many safety-critical systems, such as fly-by-wire and hydraulic systems in aircraft, some parts of the control system may be triplicated,which is formally termed triple modular redundancy (TMR). An error in one component may then be out-voted by the other two. In a triply redundant system, the system has three sub components, all three of which must fail before the system fails. Since each one rarely fails, and the sub components are expected to fail independently, the probability of all three failing is calculated to be extraordinarily small; often outweighed by other risk factors, e.g., human error. Redundancy may also be known by the terms "majority voting systems"or "voting logic".
A suspension bridge's numerous cables are a form of redundancy.
Redundancy sometimes produces less, instead of greater reliability – it creates a more complex system which is prone to various issues, it may lead to human neglect of duty, and may lead to higher production demands which by overstressing the system may make it less safe.
