What is the difference between Bangor Dufferin Avenue and Abbey Street Park and Ride?

Bangor Dufferin Avenue is listed as a bus Park and Ride, while Bangor bus and train station on Abbey Street is listed for both buses and trains.

They have different purposes, so your best choice depends on where you are boarding. If you need a train, drive to Abbey Street; if your bus specifically calls at Dufferin Avenue, use that stop. Do not assume a ticket bought for one mode lets you board the other. Check your service before deciding where to leave the car.
