TBH I didn't know CITIRAIL still existed but here is a true railroad heritage unit on the first train of the video. CITIRAIL unit 1423 3rd in tow facing forward on a westbound BNSF Z/ Intermodal train to Hobart Yard in Los Angeles. I caught an eastbound BNSF Z with Canadian Pacific unit 8745 2nd in tow mid train helper. I caught Atchison Topeka and Santa Fe Warbonnet unit 760 on an Eastbound Amazon Prime train. Fullerton is the home of freight trains you do not have to wait long at all. The longest I waited on Labor day was 10 minutes between 2pm and 2;10pm. Trains really pick up in the morning and evening. Fullerton station is the beginning of the Needles Subdivision and the Transcon to Chicago. 200 trains a day through Fullerton Railfans paradise.
