Road Making and Chalk Weathering

Just before I talk about how I make roads for my layout I want to mention Bragdon weathering chalks which I use to simulate oil stains and car tire marks. I use soot black and grimy black colors. I like Bragdon chalks because they stick to most surfaces, are self-sealing (no drying, or curing is required), and you only need to use a little. They also come in a good range of colors. Rub them on the surface and they release a bonding substance so the chalk won’t come off the model and get all-over your fingers. The trick to using chalks is to build up the effect slowly.

Now, back to the road construction:

–> I use Hydrocal for most of my road surfaces

–> I wait until the Hydrocal road is almost dry, and then I use a thin piece of wire to scratch out some little cracks in the roadway

–> When it’s dry I paint the road using a concrete color, but vary the shades a little

–> I then use an India Ink/rubbing alcohol mix (or thinned black acrylic paint) to carefully fill each crack using a thin artist’s brush

–> Lastly, I use chalks (soot black and grimy black) to simulate oil stains and vehicle tire marks.

As a point of interest, I also use chalks for weathering vertical streaks under window sills (where rain has washed down) and on roofs.

This is not just for the newbies, but some of the more experienced modelers may need a reminder as well. Most of the problems with engines, either diesel or steam, can be traced to the tracks, Take the time and care when putting in new tracks. Using the NMRA gauge to insure the track, including turnouts, et cetera are within gauge and everything is as smooth as possible. There seems to be a rush to get the new engine on the tracks and give it a run. Before you do, go and get your NMRA gauge and check the wheels, insuring they are within spec. If you are using DCC to operate your railroad, make sure you take the time to set up the new addition. I would suggest using the gauge to periodically check the various parts of the operating equipment to assure everything is alright. Even some of the best known and highly experienced modelers have been embarrassed because in the rush to get ready for an open house because they overlooked a minor aspect, resulting In breakdowns, power outage, and many other problems. I have a checklist when I am getting ready to bring on a new engine or car on my layout.
