UP 7862 leads a Z Train + UP 4014 “Big Boy” at Fort Worth, TX

I was walking around looking at UP 4014 “Big Boy” than I heard what sounded like a Train so I walked over to this spot and got the Train on video, it was a Priority Intermodal Train, the symbol for it was ZMNLA, that Train originates at Marion, AR and heads West to Los Angeles, CA at East Yard, also there were several Containers with open doors on the Train, and UP 4014 “Big Boy” is an ALCO 4-8-8-4 that was built in November of 1941, this was on 10/10/24 at 10:44 AM at Fort Worth, TX.
