The Number of Stoppages for this train are also very limited & it's schedule is damn tight . So cover up of Lost time for this train in Summer Season is not so tough . This train has the following advantages :-
------------------
1) The Dn Train 12358 trails the Howrah Rajdhani Exp (I have heard) .
2) The Up Train 12357 trails the...
more... Guwahati Rajdhani at times .
3) This train has 10 - 11 stops en route that too via the Shortest Route between Calcutta & Amritsar (via DHN - GAYA - MGS - LKO - SRE - UMB) .
4) This train will soon get a Single Electric Loco by 2012 End or 2013 Beginning after it's Route Electrification gets completed .
+++++++++
PS : A Pantry , an Extra 1st Cum 2nd AC Coach + 4 Days increase in frequency will be added advantage for this train to perform wonders on it's route :)
