Union Pacific Main-Line Ballast
Union Pacific ballast varies across a very large system. These in-stock gray and multicolor O scale materials provide practical main-line starting choices.
Union Pacific Yards and Sidings
Mix older ballast with dirt, cinders, coal, weeds, and spilled materials for a working railroad appearance.
Union Pacific Scenery Materials
Build plains, desert, mountain, river, agricultural, and heavy-industrial scenes across Union Pacific territory.
O Scale Rock-Size Reminder
For O scale, a rock product ending in 5 is small, 6 is medium and can also work as a boulder, and 7+ creates larger rock. The special 03 ending is Sand & Gravel and can also be used as rip rap.

Union Pacific routes cross many states and geological regions. Match the material to the exact subdivision, track class, and era instead of using one color systemwide.
