Looking aft from the port forward car deck access door. Note the cars all pointing aft, and the cockpit ladder locked in the down position. Further along in the shot on the far wall notice a change in height of the car deck roof into what appears to be an alcove. This is the area originally designated extra passenger space in the Mk I version of the SRN4, and is also the area where the 19m extension of the two Super-4 craft was inserted during their expansion in the '80s.
