Another Bike NY question

Bikes are always allowed as checked luggage on Amtrak
although it may not travel with you if you take the Acela
service from DC. You have to box them and be at the station
at least an hour prior to the departure. Go to
www.amtrak.com and look under Checked Luggage section. GH

I've never done Bike NY. Last year was the first time I
became aware of the ride. Last year, if I remember
correctly, the bikenewyork website indicated that Amtrak
was running some trains that allowed you to roll your bike
onto a baggage car and roll it off at in New York. I don't
see any arrangement for that this year, and I can't find
any information about trains allowing bikes to be rolled
on Amtrak trains this year. Am I missing something or are
they not doing that this year? I live in DC and would love
to just take my bike onto a train and get off in NYC.
Anyone know of a train between DC and NYC that allows
this? Based on my past research into this subject, I'm not
confident that Amtrak offers this service, but just want
to make sure I'm not missing something.
