As for the Coach/Business thing, on an Acela train, Business class IS coach. There is no coach on the train, and all Amtrak trains are 2 class setups.

If you are traveling on an Amtrak ticket and give you OP number, you get miles as you expected.

If you were traveling on a CO codeshare ticket, there is a lesser mileage accrual - like what you got. In the case of Amtrak you always lose by purchasing tickets from CO.
