I had two questions in my mind from so many months but Wikipedia Site cleared my doubts regarding Nihalgarh & Jagdishpur. The questions in my mind were as follows :-
-------------
Q1) Why does a Superfast Train like Himgiri Express stop at a MEMU Stop like Nihalgarh ?
-------
Q2)...
more... There is a mention in Encarta Map of Uttar Pradesh, of the place called Jagdishpur but I have not heard of that station's mention anywhere on IRI or any other Rail Forum. Why ?

The Answer I got from Wikipedia regarding these questions is that Nihalgarh is the nearest station to the Jagdishpur Industrial Estate in Central Uttar Pradesh(Near Lucknow).

PS : I have derived from this info that Nihalgarh acts as a Stoppage for Local Business Commuters between Lucknow City & Jadishpur Industrial Estate. I think that this is the reason why Himgiri Express acts as a kind of Local Train between NHH & LKO. This may also be the reason of NR's haste to start MEMU Train Operations between NHH & LKO after this stretch is electrified asap.
