Smartmast
The current design for OLE support structures comprises of an independent metal mast or portal with its own foundations and is separate to the track.
This means the design has to allow for a wide range of positioning tolerances and ground conditions, leading to an over-engineered solution as seen on the Great Western Electrification Project.
These substantial OLE structures have received strong resistance from communities adjacent to the railway who object to their unsightly nature.
Current equipment is independent of other line-side signalling and signage, resulting in cluttered railway corridors.
A colleague gave this some thought and proposed integrating the structures with the track and line-side signalling.
I was tasked with visualising my colleague's sketched concept. This is now under evaluation by signalling, mechanical, and electrical engineers.
Cost
A mast of this type would reduce the financial costs associated with manufacturing, installation, and maintenance.
Environment
Less energy would be used in the production and installation of the masts. Sustainable materials can also be used to produce the mast.
Safety
The potential of a projected aspect increases signal visibility, making the railway safer. Especially when visibility is low due to inclement weather.
Maintenance
The modular pods can be easily accessed and maintained. They can be easily removed and changed so that maintenance of a defective unit can be conducted away from the railway.
Remote monitoring
Built-in sensors will be able to provide data directly to Network Rail, enabling maintenance to be better targeted and reducing the need for line-side manual checks.
Customisation
The masts can be customised and moulded in a variety of environmentally friendly recycled materials that complement the surrounding environment.
Modular
The modular pods offer multiple uses and configurations. A one size fits all approach has been taken whilst considering the design.
Lighting
Lighting can be integrated to provide added track visibility in locations such as tunnels.
The prototype offers modular pods which make use of the structure’s aerodynamic openings. These are intended to accommodate a host of varied equipment.
The pods can accommodate a small LED screen, signal lighting or be used as a bracket to attach signage or larger track-side equipment and signals.
The hexagonal shape was chosen to limit the movement of the units. The pods can be accessed from both sides and allow for cabling to be fed from the mast. They are fixed to the main structure using 2 caps.
