Thanks Al!Going from memory, I believe that the door you see to the left might actually be the special items storage area. But again, I'm not 100% sure as I really didn't pay all that much attention to precisely what it looked like. I do know that it was closest to the end of the car, but I don't recall which end of the car either.
The area that you are looking for is a small (3 1/2 feet wide X the width if the car) found on the "B" end of the car. (coach, coach-baggage, and sleeper only) It is sometimes mislabeled or not labeled.
In printmans photo you are seeing the "A" end equipment room which contains the potable water tanks, the water heater, the waste treatment system, and a 10 or 12 ton airconditioning/heating system. Definitly NOT a place where I would want my bags stored. The small door you see on the left is acess to the fresh air filters for the HVAC system.

Like I said, I really hadn't paid that much attention to where it was, only that it wasn't the open door seen in the photo, since it wasn't close enough to the end of the car.
