Those in Manor Cars are “Standard” Roomettes. Slightly larger and with a cut-out bed (wider at the head than the foot)…..you can lower the bed without having to step-out into the corridor.
The Chateau Cars have “Duplex” Roomettes which are slightly smaller. In the Lower Duplex, the bed slides under the floor of the Upper. In the Upper, it lowers from the wall.
CP sold the Duplex at a lower rate than the Standard Roomette but VIA sells them now as Cabins for one……all at the same price.
