early arrivers take in the action at Metro Jct north of Krum TX

a pair of Kansas City Southern GP22ECO locomotives (2810 and 2824, both originally Western Pacific GP40s)
have just dropped off their train at Metro Junction, just north of Krum, Texas. Before long, the train will
depart northbound with BNSF Railway power.
This operation, which occurs nearly everyday, is called the "pig swap" bcause the trains are loaded with containers and trailers
