This image depicts a metal staircase on a passenger ferry or vessel, likely at the port of Thong Sala in Thailand. The staircase, painted in a vibrant royal blue, ascends from the foreground towards the upper deck, partially visible against a bright sky. The steps show signs of wear and tear, with scuff marks, areas of faded paint, and remnants of yellow and black anti-slip tape on several treads. White metal handrails flank both sides of the staircase, secured to white-painted bulkheads. On the left bulkhead, a green sign with white text reads "UPPER DECK" and "ชั้น ดาดฟ้า" (Thai for upper deck), accompanied by an upward arrow. On the right, a white metal door is visible, featuring a blue pictogram of a male figure, indicating a men's restroom. Below this symbol, a partially obscured green sign is mounted. A black, dual-fixture wall-mounted light is affixed to the right bulkhead, between the door and the staircase railing. The scene is devoid of people, activity, or interactions, focusing solely on the structural elements of the vessel. The lighting suggests daytime conditions.
