I’ve seen apparently contradictory information on these and would welcome clarification. Is it the case that the traditional four-to-a-table diner side of the CCC is the only one in use for passengers (in essence a half-size version of the regular Superliner dining car) and the C-shaped seating side is used only for staff break-out/storage? Or is the diner side reserved for sleeper passengers and the C-shaped seating side used by coach passengers? Like I say, I’ve seen both suggested and would welcome confirmation of the correct information. Furthermore, whichever of the above is true, is the C-shaped seating side ever used as an overspill from the main dining area if the latter becomes too busy during a meal service?
