Ammi Jaan kahti thi Railfanning se bada koi dharm nhi hota or koi Railfan chhota nhi hota - Shanzil Kabir

12559 arrived Ndls right after SK .. I can confirm that as I was at NDLS station to pick my parents who were traveling in SK...
In fact when SK was half way through of 16, 12559 started to do a parallel entry..
from NTES you see diff updates as they manipulate timings
There were no PF issues either... 12309 arrived on...
more...

PF13... at same time was told SK will arrive shortly (by 8:05) on npf 13 as well..
Pf 16, 15 14 & 12 were all empty..
then 12553 arrived on pf 9 (or 10 ..as I looked from pf 13 and had emu in between)
Then 12309 went to yard quickly (around 7:55)
And 12429 (running late) arrived on pf 15
Then there was a gap as only emu’s came from TKJ side (recall 03 came) and 1 sarahanpur shuttle departed NDLs (with wap7 + dead wdm4 )
All this time there were several pf empty but no train came.. and all this time the station displays showed SK to arrive at 8:05 and SG at 8:10 ... though was already beyond 8:10..
Then suddenly at 8:21 they changed PF for SK (from 13 to 16) .. the P7 soon after emerged headed on the last line..
once SK was in half on pf16, I could see SG pull in parallel headed further down the pf (maybe went to 13 or earlier.. didn’t check as headed towards my parents coach)...
