There are two more roof hatches. One at the rear of the unit where I am standingn. It acts as acces to the steam generator for passenger car heat, And a foward hatch where the water tanks are housed. These tanks suplied water to the generator. The water tanks can be seen in the last pic hanging from that hatch, but the steam generator was removed and replaced with a concrete weight some time ago. If this was a freight unit like 663 the dynamic brakes would be in the front hatch, and a similar concrete weight under the rear one.
