For Clarification,With an an example I'm raising this doubt
Train No 16227
Coach Composition SL * 6, FC * 1, 3AC * 1.5 1AC *0.5
Status
SL : WL 85
3AC...
more... : Avlb 2(CK) WL 10(GEN)
FC : Avlb 1
1A : Avlb 4
In this case will the Up gradation will happen from SL to FC Or 1AC ????
I know up gradation will be done for 3AC,but not sure for FC or 1 AC.
Please clear my doubt ....
