Pacing Union Pacific Big Boy #4014 Steam Train Highball Gering, Nebraska (6/8/23)

READ FIRST: Join us as we pace UP No. 4014 out of Gering, NE on its way towards North Platte and Omaha on the Home Run Express. Watch and listen as Big Boy accelerates its ~1,132 ton train up to about 40 mph on the South Morrill Sub, over territory that has never seen a 4000-class locomotive until today. Enjoy and stay tuned for the full compilation =) Huge thanks to @NYCTARailfan for being my pace driver. FAQ (Read before commenting): The diesel locomotive accompanies UP Steam power to provide a measure of security and flexibility in operations. The diesel can hold or slow the train speed down using dynamic braking, thus saving the cost of new brake shoes and the time needed to install them. Additionally, the diesel can be used to assist when necessary, and to extend the fuel and water supply, allowing for longer operating distances and days. Finally, as of 2021, the diesel is an integral part of the PTC system required for FRA compliance. The water overflow from just in front of the rear cylinder on the fireman’s side is the exhaust steam injector overflow port. Discharge from this port is normal when starting and stopping the injector, and when the injector switches between live steam and exhaust steam.
