Definitions

• This invention relates to access control to railway yards and stations.
• it relates to a gate for the prevention of access by unauthorised persons to train stations and railway yards via the railway lines.
• the inventors are aware of persons boarding trains without a ticket and theft of various items in train yards such as copper cables.
• the inventors are further aware that although train stations and railway yards can be fenced in, persons can gain access through the openings in the fence required for the railway lines.
• a railway gate which gate includes:
• spikes provided on the upper surface of the flat bottom with a railway line arranged in passages provided through the spikes;
• detection means for detecting the presence of a person within the tubular structure
• the tubular structure may be open topped to allow for access to overhead electric cables and to provide clearance for a train's pantographs.
• An open topped tubular structure allows for a significantly smaller diameter tubular structure, cost savings and simplified installation. In use, the tubular structure will be installed against on the inside of and in line with a gap in a fence with the gap being the minimum safe dimensions, which also generally corresponds to the width of the flat bottom of the tubular structure. The fence will partially obscure the opening of the tubular structure.
• the deterrent means may include any one or more, preferably all, of a high power sound generator, strobe lighting, smoke generator and pepper spray. It is preferable to overload all the senses of an intruder to cause disorientation.
• the pepper spray may be useful in the case of the need for riot control.
• the system may include a control room for monitoring and operating the deterrent means of the gate and for receiving images from the camera.
• the system may further include a fence which is also monitored by the control room and which fence detects and deters unauthorised entrance.
• Figure 1 shows a perspective view of one embodiment of a railway gate when installed, in accordance with the invention
• Figure 3 shows a front, side and top view of another embodiment of the railway gate, in accordance with the invention.
• the railway gate 10 in accordance with the invention, is generally indicated by reference numeral 10.
• the railway gate 10 includes a flat bottomed tubular structure 12 dimensioned to allow a train there through.
• the tubular structure 12 is open topped to allow for access to overhead electric cables and to provide clearance for a train's pantographs.
• the tubular structure is 6 meters in length and in a first embodiment, shown in figures 1 and 2, have a general octagon cross sectional profile assembled from 7 aluminium, zinc alloys or similar based metal panels 14.
• the tubular structure 10 is installed against on the inside of and in line with a gap 16 in a fence 18 with the gap being the minimum safe dimensions to allow a train there through, which also generally corresponds to the width of the flat bottom of the tubular structure.
• the fence 18 will partially obscure the opening of the tubular structure 10.
• Spikes 20 are provided on the upper surface of the flat bottom with a railway line 22 arranged in passages 24 provided through the spikes.
• the tubular structure 12 is rounded.
• a weather resistant box unit 26 is installed, which houses a processor, which is connected to a deterrent means and passive infra-red detection means for detecting the presence of a person within the tubular structure.
• the processor is also connected to a vibration detector for detecting the approach of a train to deactivate the deterrent while a train passes through the gate 10.
• the deterrent means includes a high power sound generator, strobe lighting, smoke generator and pepper spray.
• the processor is also connected to a transceiver and a camera, which transmits alarm signals and video images to a control room.
• the unit 26 is powered by a solar panel to make it a self-contained unit.
