Concrete Viaduct from castings on Stoneycombe

[Granitechops]

Following a tip on Gscalemad ( what a great site that was){ thanks Jason}

I filled in the archways with styrene formers, & comenced to in fill with concrete mix

Filling to the top, while keeping an eye on the adjoining track level bases at either side

I was getting a little short on casting by now, as the mould had gone on its round journey to another recipient, too late to make any more.

so for the last gap I used a broken bridge casting for the front, & cut down a paving slab for the back,

which was OK, as there would be plants hiding the back blank bit.

and the 'blind' bridge front was at an angle facing the end cliff so one could not see directly in to the back

I am just glad I got on with it then, when I did

this was April 2009, by mid june my CFS had got a lot worse, & I have not had the resources to do much since

The bridge sections are straight, but slightly angled to each other to accomodate a gentle curve in the track layout

As seen in this perspective shot from just below level

What I love about a garden railway, is the contrast between the man made objects & the plants,
as here
a waterside meadow, with viaduct as background

 

[Granitechops]

And the framing of a view through an arch
capturing the reflection of summer green leaves in the water
and the current rippling under the archwah

as a boy I used to spend hours under such a bridge trying to catch sticklebacks

And after just a few weeks the plant start to really flourish

one of my favourites

 

[Granitechops]

Mutterings were heard about lack of railings or parapet
so a 'temporary' solution was put in hand

 

[Granitechops]

Some old reinforcing iron suitably bent,
& a bit of old red tape
Well orange actually,as that was all that was in the store

Hello - I know this a jolly old thread now but I have enjoyed it - really good stuff. I do have a question however as I am thinking of something similar. Have you had problems with the water rising up the legs of the viaduct in an overscale way? And when they froze were they ok? I am thinking of hwo to keep the damp out of the legs of my about to be constructed viaduct.

The pictures in Posts 30 and 31 are pure magic, Don. As you said yourself, it's the juxtaposition of model and actual landscapes that weave the spell. 30 and 31 had me playing in the Tavy again under the footbridge near the Mary Tavy hydro station there- I guess you know it.

Many thanks,

Alec K

Hi Ian, there is a bit of water rising up the concrete by capilliary action, but doesnt seem out of place in the pics & it encourages algae growth just above water level, did not waterproof it, but I would say use use 1 - 3 cement-sand mix, or even 1-2.5
If you were to use a weaker mix of say 1-4 or weaker it would not be so durable

we had temps of -12 overnights in Jan-Feb this year, but no ill effects noticed on the railway structure

cant say the same about the house, the wall facing the weather frosted off great patches the size of dinner plates!!!!!

I suppose a lot depends on how delicate your piers will be, my viaduct is low & stubby with a lot of strength to it

Hi Alek, not familiar with the Tavy, but I have got happy memories of being under a bridge down Nancherrow valley, below St Just, nr Lands End, patiently waiting hours catching sticklebacks!!

Only possible because of your kindness in posting your mould to me so I could make it,
Thanks Mike
