1. A catwalk having an inner side for connection to a side of a vehicle/equipment and an opposite, outer side away from said side of the vehicle/equipment, the catwalk being moveable between a retracted configuration and a deployed configuration, the catwalk comprising:
a floor having a floor pivotal connection for being pivotally connected to said side of the vehicle/equipment, the floor being generally vertical in the retracted configuration and generally horizontal in the deployed configuration so that the catwalk in the deployed configuration has a walkway above an upper surface of the floor;
a railing pivotally connected to an outer edge of the floor; and
a guide arm system adapted to pivot the railing from generally vertical and side-by-side with the floor in the retracted configuration, upward and inward toward said inner side of the catwalk to be generally vertical and upending from the floor in the deployed configuration, when the floor pivots from the retracted configuration to the deployed configuration, and
said guide arm system being further adapted to pivot the railing from the deployed configuration, outward away from said inner side of the catwalk and downward to the retracted configuration, when the floor pivots from the deployed configuration to the retracted configuration;
wherein, in the retracted configuration, the floor extends upward from the floor pivot connection so that the outer edge of the floor is at or near a top of the catwalk, and the railing extends downward from said outer edge of the floor.
