Yup saw that..
I am regularly tracking 12024/23 preference over ECR and ER.
So here it goes
1.7th March 12274 OTs 12024 at MDP
(12024 trolls 12274 from PNBE to MDP)
9th...
more...

March 12327 OTs 12023 at DGR
(Reason given by ER that 12327 has less stops then 12023 in ER div)
2.15th March 12023 OTs 12315 at Paraj.(despite the fact that 12315 doesn't have any halts b/w JAJ and PNBE)
3.16th March 12274 OTs 12024 b/w UDL and DGR. 12024 reOTs 12274 after BWN and then again 12274 re OTs 12024 at Liluah (Gap b/w arrival only 7 minutes at HWH, 12274 Departed PNBE 5 minutes after 12024 at 8:05 and 12024 at 8:00)
....these are some memorable OTs
Apart from these many 13010,12322 were on list of OTs by 12024.
But OT of 12024/23 is something really rare.
