Selected Publications and Research
Cavenia’s approach combines the discipline of peer-reviewed research with extensive specialist knowledge of railway energy, emissions, train performance, hydrogen, batteries, hybrid powertrains, and alternative electrification. This research base strengthens technology comparisons, performance assessments, and implementation recommendations for client programs. Selected publications are listed below.
