## 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.

## Claims

### Claim 1

A barrier system for a railway station platform, said system comprising:
a platform having an upper surface, a well extending downwardly into said platform, said well being positioned adjacent to an edge of said platform;
a housing being positioned within said well and having an apex being open, said apex being approximately flush with said upper surface of said platform;
a pair of cylinders being positioned within said housing, each of said cylinders being vertically oriented, a conduit being in fluid communication with each of said cylinders;
a pair of pistons, each of said cylinders having one of said pistons positioned therein, each of said pistons having a bottom end and a top end;
a pair of posts, each of said top ends having one of said posts attached thereto such that said posts extend upwardly from said pistons;
a railing being attached to and extending between said posts, said railing being positioned on an upper end of said posts, said railing being horizontally oriented;
said pistons being movable between a stored position with said railing being approximately flush with said upper surface and a deployed position positioned greater than 30.0 inches above said upper surface;
a pump being in fluid communication with said cylinders to force fluid into said cylinders and urge said pistons upwardly into said deployed position; and
a brace being attached to said and extending between said posts, said brace being positioned between said pistons and said railing.

### Claim 2 (depends on 1)

The barrier system according to claim 1, further including a brace being attached to said and extending between said posts, said brace being positioned between said pistons and said railing.

### Claim 3 (depends on 1)

The barrier system according to claim 1, further including each of said cylinders including a cylinder gasket mounted on said cylinder and extending around a corresponding one of said posts, each of said cylinder gaskets including a plurality of cleaning bristles for cleaning said posts before said posts move inwardly of said cylinders.

### Claim 4 (depends on 1)

The barrier system according to claim 1, further including each of said pistons being telescopic and including a lower section and an upper section in fluid communication with each other such that said upper sections are lifted upwardly when a fluid is injected into said cylinders and a corresponding one of said pistons, said upper sections being attached to an associated one of said posts.

### Claim 5 (depends on 4)

The barrier system according to claim 4, further including a pair of piston gaskets being provided, each of said piston gaskets being positioned between one of said upper sections and a corresponding one of said posts, each of said piston gaskets including a plurality of bristles for cleaning said posts before said posts move inwardly of said lower sections.

### Claim 6

A barrier system for a railway station platform, said system comprising:
a platform having an upper surface, a well extending downwardly into said platform, said well being positioned adjacent to an edge of said platform;
a housing being positioned within said housing and having an apex being open, said apex being approximately flush with said upper surface of said platform;
a pair of cylinders being positioned within said housing, each of said cylinders being vertically oriented, a conduit being in fluid communication with each of said cylinders;
a pair of pistons, each of said cylinders having one of said pistons positioned therein, each of said pistons having a bottom end and a top end;
a pair of posts, each of said top ends having one of said posts attached thereto such that said posts extend upwardly from said pistons;
a railing being attached to and extending between said posts, said railing being positioned on an upper end of said posts, said railing being horizontally oriented;
said pistons being movable between a stored position with said railing being approximately flush with said upper surface and a deployed position positioned greater than 30.0 inches above said upper surface;
a brace being attached to and extending between said posts, said brace being positioned between said pistons and said railing;
each of said cylinders including a cylinder gasket mounted on said cylinder and extending around a corresponding one of said posts, each of said cylinder gaskets including a plurality of cleaning bristles for cleaning said posts before said posts move inwardly of said cylinders;
each of said pistons being telescopic and including a lower section and an upper section in fluid communication with each other such that said upper sections are lifted upwardly when a fluid is injected into said cylinders and a corresponding one of said pistons, said upper sections being attached to an associated one of said posts;
a pair of piston gaskets being provided, each of said piston gaskets being positioned between one of said upper sections and a corresponding one of said posts, each of said piston gaskets including a plurality of bristles for cleaning said posts before said posts move inwardly of said lower sections; and
a pump being in fluid communication with said cylinders to force fluid into said cylinders and urge said pistons upwardly into said deployed position.
