Service on three western Amtrak routes has been affected by Midwest flooding in recent weeks. It made my trip back from Oregon more interesting - not in a good way. Flooding in Wisconsin affected some rail bridges and access to some Amtrak stations, so my train was stopped in Minneapolis-St. Paul and we got put on buses for the remainder of the trip back to Chicago. The good news is that two of three Amtrak routes having this issue are back in full operation. If you're planning a trip on the California Zephyr (crossing still-flooded Iowa), check with Amtrak.
