Railfanning Houston, TX - w/ CPKC Tier 4 Duo! 9/22/2025

Here are three trains I caught one hot September afternoon in 2025. The first two freights passed me by while I was waiting for the CPKC tier 4 duo to come by. I end the video with a brief chase of the duo, which I have uploaded as a separate video late last year. Train 1 - UP Empty Rock Train (Westbound on UP Houston Sub) Train 2 - CPKC 871 Coke Train (Port Arthur, TX - Corpus Christi TX)(Westbound on UP Houston Sub) Train 3 - CPKC 181 Intermodal (San Luis Potosi MX - Bensenville IL)(Eastbound on UP Houston Sub/Eastbound again on UP Beaumont Sub) Thanks For Watching!
