 Canadian National Railway Co , the countrys biggest railroad, is banking on growth in consumer products and supply-chain diversification in Asia, to revive traffic on its underutilized eastern Canadian rail lines, the companys chief executive told Reuters on Friday. The tariff war and coronavirus have intensified and accelerated these trends, CN CEO Jean-Jacques Ruest said. CN is very focused to repurpose that network, which is in great shape and only running at 50 capacity, Ruest said.
