MoPac, Frisco, MKT: I grew up 2 doors from a Missouri Pacific line. We drove under/through a Frisco viaduct everyday when I was a kid. And my uncle worked for MKT.
I still drive past the old MoPac line. It's now a rail trail for bikers and joggers. The Frisco viaduct is still there with trains passing over. And MKT eventually ended up part of UP where my uncle retired from.
