Also where would IR harness 3 phase potential if it itself is running on an age old infrastructure, majority of routes not electrified, not upgraded to high speed ones.
You are right about Age and condition being directly dependent on each other. This is the reason why the condemnation is done only on Age-cum-condition basis. The locos' calculated lifetime is not a particular number, rather it is spread over a range and the actual point of failure only depends on maintenance, kind of operations that locomotive is handling etc. And if you look through the document you have shared, you'll notice that each and every component of the locomotive,right from the control stand to the traction motors also have a codal life.
