Fort Worth Help???

I may be staying with my brother-in-law a week or so this summer in Ft. Worth. I researched to see what rail lines are located near by, and to my surprise, he has (I think) a UP line in walking distance of his house. He is located right along I-35W on the west side and a few miles south of the I-820 interchange. I also noticed another line that parallels the above mentioned line to the west within a mile which I think is BNSF.

Am I correct on which lines these are? If not, please correct me.

What AAR channels would be of interest for me to monitor these 2 lines?

How frequent is travel on these lines?

What are the line division/route names for both?

Many thanks in advance!!!
