Chilcott’s Ck bridge assembly – Part III …

Hi all,

Over the last couple of days, I started weathering the Chilcott’s Ck bridge girders and piers.

To refresh the memory, this is the bridge and the weathering effect I am trying to achieve.  Even though the photo was taken in the last few years, and I am modelling 30+ years ago, I don’t think the weathering would be much less.

Chilcott's Ck bridge weathering

Following on from the previous post on the subject, the completed bridge spans had been painted with Krylon camouflage brown spray paint.  The plaster piers were also painted with the Krylon.  It is a dead flat matte paint that gives a good surface for the weathering powders to adhere to.

First, a bit of background on the Krylon paint and weathering powders.

At a local model railway exhibition that was held in Sydney earlier this year, a good mate was demonstrating his latest technique for weathering rollingstock.

Rather than me repeating it verbatim, have a read of this PDF as it outlines the technique in detail.  For those readers in Australia, I obtained my Conte crayons from an online art supplier, The Art Shop.

How Aaron sprayed the Krylon over a perfectly good model comes across as a bit drastic, but you can see the results.  The Krylon is purely there to provide a “keying” surface for the crayon powders.

So, both the bridge girders and piers were painted with the Krylon.  The bridge girders then got a good coating of a blue/grey colour then a light hint of various shades of browns to simulate the dirt on the bottom half of the girders.

The plaster piers were then attacked with a light grey colour as a base to get that weathered concrete colour.  Some white was also applied to lighten the grey in certain areas.  Then it was just a matter of using various shades of browns and black to get the streaking effect.

Below is the result so far.

Still have a bit to do, but probably not far off from being finished.  I’ve also been working on the abutments using the same techniques.  Below is a photo of progress so far.

  1. I just read Aaron’s PDF. How does he deal with lettering on the car? That rough surface is going to be hard to decal.

    What about using Krylon’s matte varnish instead of camo to provide tooth on the model? That way the original paint job is not completely covered, as it appears it is with this method.

    • Rene,

      The article was pretty much specific for that wagon model, and the technique is obviously generic as well, but on wagons where there is just lettering rather than codeboards, Aaron does just that – hit the model with Dullcote or similar to provide the keying surface. I suppose his reasoning for painting the entire wagon with the Krylon brown was to totally replace the factory silver finish and to use the powders to produce a weathered look.

    I doubt if there has been much change in the concrete piers over the years, maybe in steam days & the early Alco times there could well have been more oil, from leaks a good way to have a check is to see the colour & condition of the ballast on the bridge approaches, if dirt pretty well covers the sleepers then its pretty well ok, if clean except for the middle of the sleepers & ballast, then a lot of the weathering is likely worn off.

    I also watched the work that Aaron did & excellent stuff indeed. Rather than the Krylon I have found using the So Sonja’s tube Acrylc paint, Nimbus Grey, slightly lighter than how your piers look but its very affective. I know I have mentioned this stuf before, & I use artists brushes to apply it to a surface, as the base coat then add the soft pastel chaulks over the top & they stick very well indeed to that paint,

    I use it as the base coat or primer on all the plastic models I weather, such as the Austrains 4 wheel stock wagons, I take the bodies off & use the grey all over the inside which highlights that area even from the outside through the walls, it sticks well to the gloss like paint & that of the metail floor, I then use the pastels for the main weathering, all by brush & there is absolutely no sheen to the finished work, as it looks like real dirt,

    Anyway, things are looking good.


  3. Looking great so far! Are you doing anything to help make the streaks vertical?
