Fence thread

Local business and fences

A key feature of the proposal is the high quality toddler proof fence along each side of the rail tracks. I have suggested weldmesh as typical because the pedestrian rail crossings are an easy to view example, but that is not a definite choice and is perhaps at the bottom end.

Elsewhere I mention the rejuvenated 1.8kms of dual-use track in Joondalup, WA. The original fence was made from preserved pine poles and rails with sheep mesh to fil in the space. The new replacement has sealed hardwood uprights with stainless steel caps, 75mm satin finish, stainless steel top rails and multiple stainless steel cable infillers.

This may be a bit extreme but our goal should - at least - aim for somewhere between weldmash and the West Coast version.

Assuming 2x2kms of fence required and an existing quote for installed weldmesh of $240,000, the per-panel cost is $144. Allow for the higher aim and settle on $200 per panel. There is an opportunity for local business to sponsor (pay for) 1,666 panels. That's not too big a call when divided between all of the businesses operating in the park environs.

What makes a high class fence?

The aim is to give that park a distinctive character above that achieved by excellent funtional characteristics and thriving plantations. The suggestion to exploit railway history is part of this.

There needs to be something iconic, a symbol or colour, style of park furniture etc. that will be firmly connected to the park and mark it wherever it appears. I can see it like a virus where a bit of land is acquired or otherwise available and our park virus takes over.

The fence doesn't need to be of stainless steel, but it does need a lift above simple weldmesh (for example). The poles can be colorbonded in the park colour and given a special pole cap, the top folded rail can be reinforced in a distinctive way.

Please don't think I'm selling weldmesh, it's just convenient for discussion.

How close to the rails can we plant?

The 1998 study quotes Bayside Trains as allowing planting no closer than 3 metres from the nearest rail. The reason is to allow for sleeper replacement and weed clearing.

The same study discusses areas where the bike track fence is closer than 3 metres and describes how the wires on a preserved pine post and rail fence can be easily removed for sleeper work. From later statements it is reasonable to expect that this was accepted by Bayside.

An answer:

  • A fence such as weldmesh has easily removeable panels if needed for sleeper work.
  • The aim will be to prepare for planting, and choose such plants that weed clearing will be eliminated or greatly reduced.
  • There is another requirement that sightlines for signals are not obstructed by trees. This seems easy to satisfy.

More width without getting wider

There are hundreds of metres of the bike track where there is a solid wall or high fence immediately next to the track. Given space to move the rack 600mm away from the wall adds an effective 300mm added to the width of the bike track. A rider can go right to the edge of the track where the walls would have kept them at least half a handlebar width away.

The 600mm can be planted with appropriate low plants.
