I noticed you edited over my recent edit here. Can you tell me what was the mistake in my edit?

This changeset have so many issues

You may have added the address incorrectly. You have added `addr:housenumber=24 Rajkrisna Ghosal Road`, here it seems like 24 should be the house number and Rajkrishna Ghosal Road the street. In that case the correct tagging should be
...
addr:housenumber=24
addr:street=Rajkrishna Ghosal Road
...

In this changeset you added a name "Gramshalika - Moregram Rd via Kuli" to a road. According to the convention of OSM naming, we do not add abbreviations of words in the `name` tag. Also, I don't think the "via ..." part should be included in the name.

I feel like there are many issues with your edits for Bus station. The addr tags does not have proper values and it is clearly not a building.

As far as I understand, the naming convention in OSM discourage abbreviations such as Rd, for road. It name should have the full word "Road" instead of Rd.
Also, although I couldn't see the whole thing clearly as I was in the car, but the street sign clearly uses the word Road. So I hope you or someone from the Ola team reviews these.

A lot of your edits in this changeset doesn't use the proper tagging scheme. Please correct. Also would be nice if you had better changeset comments instead of a bunch of hashtags.

Your edit for this building has a lot of conflicts and the shape is not mapped quite correctly. As you can see, the building crosses over a street.. If you don't mind, I would like to correct the feature with your help.

In this and some other changeset, you have use the `name` tag to what seem to be `addr:housenumber` tag; e.g. `name=174`. I feel like this tagging scheme you are using is incorrect.

I have noticed that in some railway platforms you have used `highway=steps` in combination with `bridge=yes`. Is that the correct convention?

Just so there is no confusion, this is only for the way that I gave linked above in my first comment.

From my experience at the location, the road is too narrow for a 4 wheeler but pedestrians regularly using that road. Bicycle and motorcycle are allowed. The road is lined with houses on both sides. In my opinion `highway=pedestrian` or `highway=service + service=alley` with additional tags for access is how we should tag this place.

One of the road tagged as `highway=unclassified` is wrong. The road is not wide enough for a car. And the tag should reflect that.

Your use of `highway=primary` seemed odd to me. Can you please explain why you tagged it as such?
