Until the OP comes back, we won't know for sure if s/he's riding a superliner or a viewliner.
S/he says Chicago to NYC in a superliner - but does s/he mean the CL with a transfer to an NER? Or does s/he think all trains out of Chicago are superliners and assumes the LSL or the Cardinal is a superliner?
I think it's probably the CL.
I was assigned bedroom 011 on the first level next to the luggage area.
I figure that's a good room, right?
That obviously describes a Superliner, and since it doesn't seem like the OP has traveled in an SL sleeper before, he was probably told the layout of the car by Amtrak, who would most likely get the car type right.
That said, back in January, I called Amtrak to get some baggage policy info (if I could check a bag at a nearby station I wasn't departing from), and they said to just put the bag "In the baggage area downstairs". I was in a Viewliner Roomette on the Silver Meteor. So I guess it doesn't really matter what Amtrak said to the OP (if anything) about equipment type and layout in the first place.
