I have no problem with you personally. I am against misuse of a popular, publicly used Railway news oriented keyword for promoting personal non-news blog posts.
You should not use this keyword if your post does not contain any news link.
If you genuinely put up an IR related news of Indore station or an Indore-linked train and put this hashtag with that news, nobody will object to it. Maybe I will even rate it "Great" or "useful"
For...
more... eg. this particular post where you showed diamond crossing. There is no problem with the photos, and your post. Photo is good, post is good. But why did you put Indorenews in the post? Where is the news article? Where is the news entry website link?
I and many other people native to Indore region live in other cities. We like to get updated about IR related news and developments linked to Indore and around. So we search the keyword "Indorenews" on IRI once in 2-3 days. Imagine - will we like it when instead of a news article, the first result is a blog post with some pics of tracks, station etc. but nowhere there is a news? Isn't it a misuse of the hashtag?
Hope you will understand.
