Border can be very bad. Have waited up to 3 hrs northbound and 21/2 hrs on return. This was a weekday. Go early or late and stay away from weekends. Train is a beautiful ride on the new Talgo train. 1 AM train from King St Station to YVR. There is an afternoon train to Bellingham about 30 minutes from border. There are also 4 Amtrak Thruway busses each day, SEA-YVR in addition to the train.
