Elevated track

Hello, I foresee the installation of my future (in a few years…) garden train at height.

So I am thinking to install it on pressure treated wood (class IV) structure.
I think to made some sort of ‘flowerpot’ in the same structure as the track support can help improve the overall look.
Legs could be installed on adjustable terrace supports. With the weight of such ensemble, especially after have filled it with ground, that shall not move.

That have a cost, which can be estimated around 35/40 Euros per linear meter for the wood cost. Plus some stainless steel screws and … the track and ballast. That shall end up to 55/60 Euros per meter .. ouch. And the plants and ground...

Please find below some prospective drawings. What do you think about that ?

Impressive professional study.

There is a lot to be said for raised track especially as one advances in age.

I don't think that 55/60 euros per metre is actually that expensive if you compare the manhours for ground preparation and potential earthworks using other methods.

A modest 35-40 metre oval would cost around 2000€...The price of a decent live steam loco, a Club Med holiday or a 'shoe and frock shopping' trip to Galerie Lafayette.....mmm

Carl, you are far to old for a Club Med holiday and you look ghastly in frocks and heels so just sticl to chuffers eh?

Yes you did tell me that when we last met.

So now we know what went on at the "Recce Weekend"

Seriously back to the subject. On the track plan of the curve I notice that it is a compound curve, something not many people (inc. me initially) employed when building their railway.

Pierre can you tell us what the radii are that you propose. My eyesight is getting very bad.
It looks like 2500mm and 1550mm. If that is correct how and why did you arrive at those figures?

If people are planning a new layout using setrack, LGB or similar. It makes a big difference adding a larger radius curve piece ahead of the main curve especially when using R1.

The values you have read are correct.
Is it possible in this forum to have a displayed image linking to a larger image ?

The radii are the results of decisions. It was initially round values, but as I have modified the geometry, it have slightly changed. I have made the junction by using the 'tangent' function of Autocad.

The best should be having a variable radii, but it looks difficult to do. On the IETB site they are showing a 'clothoïde' curve http://fr.wikipedia.org/wiki/Clotho%C3%AFde , but they should have explain how the guy have done that.

Yes it is Pierre but at the moment you will have to write some of the post/page in html.

I have the coding for it if you want. It's quite simple.

Please see separate 'test page image linking'.

Our track here in Le Dorat will be part elevated when construction starts next spring.Instead of buying timber for the elevated sections,we have been buying fagall(hope thats how it is spelt) from the local saw mill.Although bought for the wood burner,we have managed to sort out approx 15% for use on the railway,and its all oak.So far I`ve managed to buy over 250ft of tenmille track on average at just under £2 per foot from various sources and with the saved fagall,should have a cheapest steam loop on the layout.

Mind being born and bred in Yorkshire helps.

Hi Van

Does your post mean you're back on French soil?

Your Lawley is enjoying its test running on my ELEVATED TRACK, but I feel slightly guilty, why not pop over and ease my conscience.

Besides Carl keeps making improper suggestions about converting it to a tram!

Yes Brian back home till next Sunday.If I may I`ll give you a ring when the weather inproves and pop over on the bike,its needs a run.If not I`ll see you at Geoffs in July.By the way did you do any tree felling?
