THE arbitrator appointed to resolve Canada’s railway dispute to protect the North American economy has ordered workers at the country’s two major railways back to work so both can resume operating.

Saturday’s order means that Canadian National (CN) will be able to continue operating the trains it restarted Friday morning just over a day after it locked out workers. 

But Canadian Pacific Kansas City (CPKC) is unlikely to be able to restart its operations before this morning, when workers were ordered to return.
