Track train dynamics analysis and test program: Methodology development for the derailment safety analysis of six-axle locomotives [PDF]

open access: yes
The operational safety of six axle locomotives is analyzed. A locomotive model with corresponding data on suspension characteristics, a method of track defect characterization, and a method of characterizing operational safety are used.
