SLN diversion is good...But this will cause one bit of problem.
If 18103 is speeded up , its Impossible to get Vacant Platform at LKO. Between 1300 to 1600 , the LKO station is severely jam-packed with Trains coming from nearly ALL directions.
Plus this will also cause Arrival timing at ASR to be somewhat 0400-0500hr which is awkward as compared to 0620-0630 arrival (atleast we could complete our FULL sleep and freshen up ourself before alighting ASR).
And...
more... If 18104 is speeded up , abhi itne slow schedule hote huye bhi average 1hr delayed arrive karti hai TATA , after speeding up , 2-3hrs delay normal ho jayega.
But agar schedule maintain karti hai , toh i would say it would be BEST for Odisha and WB people if it arrives MGS-TATA ahead of Purushottam express so that Hume Ek good option mil jayega fro travelling Amritsar to Odisha by Connecting journey with Jallianwala Bagh Express (ASR to MGS/TATA) and Purushottam Express (MGS/TATA to Odisha).
