I just noticed that effective September 1 the rail schedules from Paris to Bayeux change. What was a 2 hour trip will now usually take over 4 hours, and as much as 5 hours, and require either an extra connection or long layover in Rennes. The earliest weekday return to Paris is at 0724 arriving 1140. a 4-hour 16 minute trip with two connections.
Just a heads up for those traveling in the fall. I had to change my plans for Normandy and will probably drive rather than take the train.
