RailFans never grow old

No Terminal change for Sealdah-Puri Duronto exp will be done. Sealdah-Puri gets passengers and this train is for huge no of passengers of North 24 Parganas, South 24 Parganas, Nadia districts, and parts of Kolkata for these districts Sealdah is a nearest station and had very good direct EMU/ MEMU connectivity. This train was given to cater passengers of these regions.
For these districts passengers Santragachi, Shalimar stations are far away and not very smooth communication present there.

Would not happen bro. The train is important for people from northern part of kolkata and the only connection for puri bound passengers from the other side of hooghly. SHM/SRC passengers have loads of trains for them. Furthermore the extra time due to this extra route from sealdah to andal is quite useful for an hour of extra sleep which is essential in my opinion. 7-8 hrs of sleep is necessary for a fresh next day. Had the train started from HWH/SHM, people would get less than 6 hrs of sleep most probably.

No Terminal change will be done for SDAH-PURI DURONTO exp. This train is for South 24 Parganas, North 24 parganas, Nadia districts people and parts of Kolkata say North Kolkata area people only. This train was given to cater these areas passengers. If you remember, as far as i remember the same year when SDAH-PURI DURONTO EXP was Announced that year SHM-PURI Exp was also announced together with this train. The main objective of RB, RM was SDAH-PURI DURONTO EXP will be for outh 24 Parganas, North 24 parganas, Nadia districts people and parts of Kolkata say North Kolkata area peoples and SHM-PURI EXP will be for Howrah, Hooghly, Parts of Kolkata passengers. Both trains got announced together in same year Railway Budget.

Yes I remember even I want it to become it daily.

ER is always ready to run this Duronto exp daily as it gets good passengers all though the year. ER even runs SDAH-PURI Special trains in peak seasons, as Puri train from Sealdah is always in a demand for the reasons i told earlier. But slot is a problem in SER. Specially at Andul this crossing-over hampers speed of many trains in very busy HWH-KGP Section. For Duronto exp priority is high, SER cannot keep it waiting at Andul outer for clearance, also TT at Andul is a peak time then. Special trains can wait at outer for clearance and its TT is also different so no problems.
I also think SDAH-PURI DURONTO exp can be made Daily.
