SD70ACU Deadend Train

Description

SD70ACU Deadend Train - In 2021 a bunch of rebuilt SD70ACUs on NS were sold to Progress Rail, so a bunch of stored engines were stenciled with PRLX logos and on this day, a newly rebui.t AC44C6M lugged a whole bunch of ACUs. I believe there were 16 ACUs that the GE pulled up the hill.

34 years old. Moved from Long Island New York to Altoona PA in 2009. Visited the NS Pittsburgh Line years before moving. I have become a fan of Steam Engines over the last 5 years or so. And the Union Pacific Steam engines are a big hit on my list. Exploring the country little by little when I have time.

About the Locomotive Class

GE AC44C6M

The GE AC44C6M is a refurbished Dash 9 locomotive from GE Transportation Systems that has 4,400 horsepower (3,300 kW) of AC-traction. Since September 2015, GE (now Wabtec), American Motive Power, Inc., and Norfolk Southern Railway's Juniata and Roanoke Shops have been doing AC44C6M rebuilds. The AC44C6M replaces the Dash 9's DC traction motors with alternating current GE 5GEB13B7 traction motors while keeping the 16-cylinder 7FDL-16 prime mover that was previously used in the core locomotive. The rebuilds still contain the original Dash 9 units' underframe, engine, and radiator compartments, but they have new wide-nosed cabins, a new front hood section, and a new inverter cabinet. The cost of converting a vintage Dash 9 locomotive into an AC44C6M is only 50–60% of purchasing a brand new Tier-4 Compliant locomotive. In comparison to an un-rebuilt Dash 9, the AC44C6M is found to have an improvement of 17% in fuel efficiency, 30% improvement in reliability, and a 55% improvement in haulage capability according to Wabtec.
