Rock Island Main-Line Ballast
Rock Island routes crossed the Midwest, plains, and Southwest. These pink-granite, medium-gray, and central-route choices provide varied G scale starting points.
Rock Island Yards and Sidings
Mix older ballast with dirt, cinders, coal, weeds, and spilled materials for a working railroad appearance.
Rock Island Scenery Materials
Build prairie, grain country, industrial cities, small towns, yards, plains, and Southwestern connections.
G Scale Rock-Size Reminder
For G scale, a rock product ending in 6 is small, 7 is medium and can also work as a boulder, and 8+ creates larger rock. The special 03 ending is Sand & Gravel and can also be used as rip rap.
