2 weeks back i saw 12649 at UBL. It was jam-packed but not sure if it was full till KCG or NGP or JHS or NZM. And 12650 also was full towards YPR so i guess it is somehow still running in profits (no comments on e2e journey though).
The interesting part on the day I was at UBL to board RC was there were 4 KSKs almost at same time as 12650 n 22685 were running late. So I am sure there would have been lot of confusion for the ppl who were boarding any of these 4 trains at UBL.
