Beginning next week, Amtrak train routes from Chicago to Port Huron and Pontiac, will be seeing some cancellations and delays until early May due to some needed track work. That includes the Blue Water area with the service that ends in Port Huron. According to reports Amtrak’s trains on some routes will run two hours earlier than normal.   The passenger rail service says certain trains will be cancelled Monday through Wednesday, while slowdowns of up to 90 minutes will continue until the work is done.  According to reports, during those three days, Amtrak will transfer passengers to buses for the Kalamazoo, Battle Creek and Jackson stops.
