I have just received an older Atlas model that appears to have the older Lenz non sound dual mode decoder in it. It runs fine, very slow creeping speed at step 1 on 28 speed steps. HOWEVER...the locomotive makes some serious loud humming noise while it operates. I have verified the jumper is in the DCC position and I am not trying to run it on DC power. This model would be spendiforous if not for the motor hum.  I have no previous experience with Lenz decoders in any scale.

I found this:

This video is the first in a serie, where we´re building a beginners style Model Railroad from start to end in only 18 days. The layout measures 1.5 x 2.5m (5 x 8ft) and can therefore be built in most bed- and living rooms.

I have used the old alcohol/india ink for staining wood, but the color choices are limited.  There are lots of acrylic based washes that work well on plastic and resin, but are there acrylic washes and stains that work well on wood?  Water based washes tend to warp wood and also raise grain and "fuzzies".  Any ideas?

thanks,

Rob
