WINONA, Minn. — The national passenger rail service Amtrak canceled its trains through Winona for fear that frigid weather has warped tracks. Snow and ice accumulation was also a problem, Amtrak said. Cancelled:
> Borealis. Through Friday both ways between Chicago and St. Paul.
> Empire Builder. Through Saturday both ways between Chicago and Seattle and Portland on the West Coast.
Alternative bus transportation was being arranged, Amtrak said.
