A Loco number can hav limitless train option & whn u found that to Tag a Loco to various train gonna lead to its reflection @ Train's page, tagging shld hav been avoided till u get revert/modification frm Moderator!!
Instead it seems like approx daily, the Loco number gets changed by you for many of the trains!!
Kindly hav patience to tag Loco with trains till Train hauled by Loco remain to Loco Page, not altering train's page!!
