The World's Largest Steam Engine! UP Big Boy No. 4014 On NS Southern Tier In Darien, NY!

READ: Shot on 6/11/26, No. 4014 makes its way out of Buffalo and onto Norfolk Southern's Southern Tier Line. Trailing tonnage behind the main tender is approximately 1900 tons including the two water cars, two diesels, and 16 coaches. Here we see the train working up a 0.6% grade through Darien, NY. Enjoy =) FAQ (Read before commenting): 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. The diesel locomotive, while no longer necessary for PTC compliance, will continue to periodically be used where it is expedient for steam locomotive fuel conservation and assistance on long, sustained grades for power & dynamic braking.
