Abstract
A railway passenger gate assembly includes a platform having a well extending into a surface thereof. A housing is positioned within the well and has an open apex flush with the upper surface. A pair of vertically oriented cylinders is positioned within the housing. A conduit is in fluid communication with each of the cylinders. Each of the cylinders has one of a pair of pistons positioned therein. The pistons each have a bottom end and a top end. Each of the top ends has one of a pair of posts attached thereto. A railing is attached to and extends between the posts. The pistons are movable from a stored position with the railing being approximately flush with the upper surface or in a deployed position positioned above the upper surface. A pump in fluid communication with the cylinders forces fluid into the cylinders to urge the pistons upwardly.
