This website presents the topics and outcomes as well the team working on two complementary research programs (i) transport modelling and (ii) optimization of railway operations. Both research programs fall under the umbrella of the CN Chair and are directed by the Chair holder, Emma Frejinger, in collaboration with other researchers. The research is mainly funded by the Canadian National Railway Company (CN) through the CN Chair on Intermodal Transportation (2013-2017) and the CN Chair on Optimization of Railway Operations (2017-2022), NSERC Discovery and Collaborative Research and Development grants as well as Mitacs.
