In another shadow in the lower right is a lantern. I'm glad that it has not walked off. In the far quadrant, we can see a dining area. The black chair in the top middle is obviously up in the copula. I assume the close door is a closet and the far door is a refrigerator. Below are closeups of the dining area and copula. The dining area was probably also used by the conductor as a desk to do his paper work. Very few computers existed in the world in 1948. The quadrant with the sink is opposite the dining area.
an initial study of handbrakes indicates the brake wheel was near the top rather than the bottom until after the 1960s.
