Many thanks, Robert.  I think I've heard it called a "side oberservation car" as well...but not sure if this is the correct nominclature.

Yes, they are blue cars with yellow

My brother-in-law collects Via Rail passenger trains.  There is a car that we don't know the name of.  It looks like the standard passenger car, but it would be the last car and has a half-moon black deck on the tail end...looks like an observation deck for personnel?

Can anyone tell me what the name of this car is so we can shop for it?

Thanks!
