I’m researching on bridges, as I will need three of them in addition to the Bietschtalbrücke. I decided to buy two Kibri 39720, ”Hölltobel-Viadukt”, as a test pilot for the double-track line:

These plastic bridges are pretty cheap, and can be kitbashed. However, the out-of-the-box look is very... plastic:

I re-shaped and modified the originally single-track bridge. (The valves at each end of the bridge, will be used for one of the new bridges.)

As I would like to use the same paint method for all three bridges, I wanted the paint job to be simple and easy to re-produce. Trying to find some real prototype examples from the Alps, I noticed that there generally is a significant amount of lime and light brown colors on - and around - the stones:

After some testing, this is how I’m doing this now; First, I add a basic surface of Vallejo primer:

After this, I use these acrylic paints:

When the primer is dry, I add some Burnt Umber using a sponge. I also add some stains with a sponge, using e.g. Black Ivory:

Next step is to add a ”white” wash based on Titanium White and some water. I also add very little Burnt Umber to make the paint more off-white. The mix has to be repeatedly tested and re-designed, and finally you have the right wash to add:

Note that the iPhone images don’t really justify the real object... I’m pretty happy with the final result, and I will probably use the method for the additional bridges:

Great job PeFu! Your technique worked very well for doing the red bricks with white mortar, I may have to try it myself for those red brick buildings.

I can't tell from your last photos but the white wash may have taken too much red out of the colour but I look forward to seeing the final photos.

Hello Peter,


What a fine piece of work !BigGrin

As you can see from the attached images, I am partial to bridges on my layout but none as beautifully
prototypically finished as you have shown - a magnificent effort by you !! ThumpUp

Thanks applor! I believe it’s the daylight that makes the ”stained” burnt umber look more red than brown-ish on the photo. Actually, I wanted the bridge to be more grey/light brown/offwhite, as the prototype pictures above. Below, the bridge is testing its final location. Note that it’s more of a backdrop than a bridge, as I will not add an arch on the opposite side... I’m a cheater!

Hallo Peter,
Thanks for showing the position on the layout, with a very clever use of the single side.

Together with PJMarklins' views on his layout, it shows how bridges do make a layout interesting.
Not to mention the real-life civil engineering challenges they overcome.
