Close up of image 'mrls302' showing Lawley Street 'B' Signal Box and opposite the single-storey building housing Lawley Street's main yard offices, mess and stores opposite. The steps up to the signal box are off set in relation to the door which is a feature common to Midland Railway signal boxes. This was to prevent the signalman, or 'bobby' as he was known in railway parlance, from accidentally falling down the steps when leaving the box at night or poor weather. The signal box was fitted with a cantilevered cat walk under the windows to facilitate their cleaning which in the dirty smoky atmosphere of the goods yard would certainly need to be on a regular basis.
They were accessed from inside the cabin by sliding open one of the windows and stepping directly on to the walkway. The rain water from the room is drained via gutters and the drain pipe which fed the water tub next to the open door. This door provided access to the mechanics of the signal box where the levers pulled by the signalman would pull or push the rodding or wires operating the points and signals. Adjacent to the signal box was the toilet facilities which would be a chemical closet rather than a 'flushed' toilet.
