Question about tracks in Stanton, CA

My in laws are considering moving to the area to be closer to the grandchildren, and one of the places they are considering is on Katella, near Western Avenue. Since I can't go out there to look, I can use my Google map skillz to look for any potential issues. And I see tracks that appear to be freights, heading north, halfway between Beach and Western that then turn east (extensively) and west (appear to end before Knott ave). I'm told these are UP tracks, so I'm hoping someone here can help me.

Any idea how much traffic these tracks see, especially in that stretch from Chapman to Katella, and east north of Katella to Dale street and beyond?

Thanks!

3 days in the new place, haven't heard a train yet!
