Amtrak is expanding its bike service to include the Empire Builder, the line that runs between the Twin Cities and east to Milwaukee and Chicago and west to Seattle and Portland.

The service arriving Monday in St. Paul will allow passengers to bring their two-wheelers on board trains. A celebration will be held from 7:15 a.m. to 8:05 a.m. Monday at Union Depot in downtown St. Paul.

Minnesota Department of Transportation Commissioner Charlie Zelle, Ramsey County Regional Railroad Authority Rafael Ortega, and Amtrak's director of Long Distance Routes Jonathan Lombardi will speak during the celebration.

Amtrak allows passengers to roll standard full-size bicycles onboard and store them in bicycle racks on select certain trains, which now includes those that stop in St. Paul.
