What source do you have for this pipeline since it isn't visible form above? And what is it? Does it really go beneath all the buildings?

FYI, you don't need to add "Area=yes" tags to the features like parking lots or buildings as this is redundant.

FYI - individual sections of parking shouldn't be mapped as seperate parking lots since it is all one lot.

Buildings can be squared using "q"

What in the world is going on here?!? Numbers for names but different from addresses?

Plus, none of them are squared with right-angle corners?

Most of these "abandoned" railways do not have anything on the ground with no ground truth. Specifically:
way/99652729

These "abandoned" railways should be moved to OHM and removed from OSM since only things that actually exist on the ground and can be verified should be mapped.

Furthermore, these railways definitely do not cross I-70.

Can you elaborate on what you did, rather than requesting someone to review your edit?

I mean like squared angles or 90 degrees. :D

Definitely not just squares! The outlines are pretty good other than that! :D

Segment referenced in the second comment:
way/304325177

It seems very unreliable to be adding segments that don't have ground truth across a freeway.

Additionally, can you elaborate on why you readded a "razed" railroad that has been mostly overbuilt by a freeway, I-190? There is definitely no crossing across the freeway. None of the aerial imagery nor street-level imagery have any railway, razed or otherwise going across the freeway.

Since there is no trace of this on the ground since the western segment has been overbuilt and long replaced by a major roadway with NO crossings across the freeway, it really shouldn't be mapped in accordance with OSM guidelines of only mapping what is on the ground and can be verified:
osm.wiki/Good_practice#Map_what's_on_the_ground

Can you elaborate on why you readded:
way/97788410

Is there really evidence of a railway going through multiple buildings and down the middle of multiple roads? There is evidence of rails on any aerial imagery that would be considered "razed" and there is no obvious RoW. It has been completely overbuilt by new buildings, railways, and roadways.

None of the buildings are square. "Q" can be used to square them.

You can square buildings using "Q". None of the buildings added in this changeset are square.

Also removed some features that no longer exist with no trace remaining that have long been overbuilt been new features, buildings and ponds.

It would be. Good catch. I'll take care of it.

A number of these railways were converted to abandoned railways, and I don't think that is correct...

changeset/135162196

....And they were never removed...

Do not change valid roadways to cartpaths. This is not correct and has been reverted in part or full.

What source did you use? It looks like it could be unnamed.

What source did you use to add the name of these business/residential areas?
