Some of the Amtrak Northeast Regional Trains -- not the faster Acela trains -- run from EWR Airport Rail Station to Washington, DC; others run to Philadelphia, where connecting service to Washington, DC, is available. You might consider checking schedules and fares from EWR Rail Station to Washington, so that you don't have to get yourself to downtown Newark just to board a train.
