Main Line vs. Yard Ballast

Use track color and texture to show which tracks are maintained, old, busy, dirty, or lightly used.

Main line

Cleaner, deeper, and more consistent

A maintained main line normally has a more defined shoulder, fewer weeds, and a consistent stone color. Fresh repairs can be shown with a lighter patch that has not yet weathered to match.

Defined shoulder profile
Consistent regional stone color
Less exposed dirt between ties
Localized rust and brake dust

Yard & industry

Flatter, darker, and less uniform

Older yard tracks collect dirt, cinders, spilled lading, oil, weeds, and repairs made with whatever material was available. The result should look less carefully shaped than the main line.

Mixed stone and exposed soil
Coal, cinders, grease, and oil staining
Weeds along lightly used tracks
Uneven shoulders and drainage

Create a believable transition

Do not switch from clean gray to black yard material in a perfectly straight line. Blend the mainline color into the siding, then gradually increase dirt, darker stone, and weeds as the track enters the yard.
