Photographer's right in india

In India all rights are limited in public interest., moral, decency and so on. Read the Classic Judgment of  Supreme Court delivered by Constitutional Bnch of 9 judges in Justice K..S.Puttuswamy Vs UOI 2017..or the Privacy case.

Greetings!

Right to Privacy is a well recognized right in India; even though the law does not prohibit capturing photos in public areas, the source/ subject that is captured can be having the right to privacy. In an instance where, as you mentioned above, if you capture a house that belongs to someone else, a person, it can create conflict regarding their right to privacy. 

Moreover, under Section 147 of the Railways Act, without prior authorisation no one is allowed to cross or walk along the railway tracks. Therefore, your action can be considered illegal.

Interfering with the privacy is objjectionable,  much less an offence. You can'nt justify showing any public exigencies.

you yourself said that the place where you were doing photography was private property of railways.
