You get elite status miles and segments, but only on the qualify markets and services.
Qualifying Services
--------------------
Acela Express & Metroliner (Acela Regional, Keystone, and other services DO NOT qualify)
Qualifying Markets
------------------
New York Penn to/from Rt. 128, Boston Back Bay and Boston South Station
New York Penn to/from Washington Union Station.
If you didn't see a station mentioned it is not included. That means if your origin or destiantion includes any other stations (including New Carrolton, BWI, Newark, Metropark, New Rochelle, etc..) you won't get Onepass miles.

I also have an additional question: Do I get Onepass elite status miles and segments for a trip from Philly to DC or only from Newark to DC on Amtrak Acela?</font>
