Handrails or bannisters
It is one word "staircase" (open flight of stairs, usually with rails).
The space under a staircase is called a spandrel.
The inside rails inside of the main rails are called guard rails. They are there so that if there is a derailment the train will stay within the rails instead of off of the trestle.

The staircase along the periodic table is called the "staircase of metalloids" or "zigzag line." It separates the metals on the left from the nonmetals on the right and helps to distinguish between the properties of elements in different regions of the table.
To remove a staircase you will first have to remove the posts, and the rails. Use a drill to remove the screws, and then use a putty knife to break pry the glue away from the pieces. Remove the bolt that attaches the rail to the stud. Remove the carpet or stair treads. Remove the frame along the steps.
The element inside a staircase is commonly referred to as the "stringer." Stringers are the inclined boards that support the treads and risers of the staircase, providing structural integrity and stability. They run along the sides of the staircase and can also be found in the center for wider staircases.
