SUBJECT: Locomotive Standards (Safety & Noise)
KEYWORDS: Hybrid locomotive, battery, lithium-on battery, advanced lithium-on battery technology
ABSTRACT: Norfolk Southern Corporation (NS) and Pennsylvania State University tested several different battery systems in hybrid locomotives. Advanced lithium-ion battery technology was the only kind that displayed the capacity to perform in heavy switching or local service. Testing proved hybrid locomotives could reduce emissions and save fuel, sometimes in significant amounts. However, even with the best assumptions taken into consideration, these locomotives would require high annual operating subsidies.
