With Reference to Capturing of UP Sealdah Rajdhani with Duronto liveried 30245 GZB WAP7, I have had some questions regarding the location I had used to capture the same.
Attached picture is of 19605 Kolkata Chitpur - Ahmedabad Sare Jahan Se Achcha Express coming out of Bally Bridge being hauled by 23352 ASN WAG5-A.
Bally Halt Station is located just next to this bridge. That is once this train would have had crossed this bridge, it would instantaneously enter Bally Halt Station.
If...
more... you open this picture, then please look at the house at the extreme angular left. This being a highway, there is another perpendicular road which runs just beneath it and there are quite some stairs to come up to this road. Once you come up to the road, you need to cross two dividers to come close to this Bally Bridge to have a clear shot from the road.
The picture of the Rajdhani was clicked from the first divider (From the House) as the Train (Sealdah Rajdhani) was just about to enter this Bally Bridge.
