Regular people go to see Taj Mahal. RailFans go to see Ghaziabad Jn. - Praveen

bro.. as far as my intuition is concerned they're making cluster of 130mps trains like Rajdhanis..
Purushottam n Mhabodhi got 130mps and arrival time me 10min gap hai dono me.
Poorva ko 2014 me 6am ka arrival diya gaya tha later withdraw kar ke 07:35am kar diya gaya..
agar again 6am milta hai to Poorva n Durontos (AD HD BD) ka cluster.....
more...

12393 n 12309 ka arrival 10min gap pe hai..
same way me evening me Rajdhani ke sath SK ko departure diya jata hai (130mps se pehle se hi)
agar SK ke baad ka departure dena hai to SK ke turat baad ALJN EMU hai n trust me IR not gonna shift that train..
Poorva ke liye hi shifting karni padegi.. take an example..
RNC Rajdhani- 16:05
BBS Rajdhnai - 16:15 (right now it departs at 17:05)
SDAH Rajdhani- 16:25
these three trains has no halt at ALD so they can run on 10min gap ... yeah RNC GR has stop at ALD bt we all know CNB pe RNC Rajdhani ka OT bohot baar hua hai SDAH n HWH Rajdhani se.. so NCR can allow unscheduled OT of GR by BBS n SDAH Rajdhani..
now
16:55 HWH Rajdhani
17:05 PNBE Rajdhnai
17:15 Sampoorna Kranti..
17:25 Poorva...
agar BBS Rajdhani ke timings ko shuffling nahin karta hai IR to fir they can give it departure after SDAH Duronto..
lets wait n watch
