I was told about this room by a person known as "Inch in ear" so i went to check it out and was suprised to find this room. To find this room go down the steps to the right of the transit elevator and walk down the tunnel at the rear of the subway (Beware of train) and keep an eye on the left of the tunnel to find a gap in the wall to find the usless but secret maintenance room. This was added in the halloween event plaza so it may not be in the standerd plaza.
