I did some test samples to make sure it was the right size and to check my process. It is PERFECT!!! This real rock ladies and gents!!! All the products I have purchased have been great!!! Easy to work with and beautiful when done!!! That's why I got a bigger bag than a sample..HA! I knew it would be awesome!!! Will definitely be a purchaser now and going forward. Lead time is long but..remember the 6 P's. If you read this and don't know, find me!! ARIZONA ROCK AND MINERALS!!! Real rock for modeling!!!

Was Sent HO Scale, Not O, But Like it Better

I ordered O scale,but was sent HO instead. It's all good though because it actually looks better for my purposes as a ground cover in a roundhouse and engine service area. I like the variability of some of the contents as it reflects reality of a backwoods railroad, which rarely is pure to one size and color.


Best Ballast out there!!!

This stuff is Excellent!!! It doesn't float away like some other products I have used when you add glue and water. I won't buy any other brand!!! I highly recommend this to anyone building a Model RR or Diorama!!!! As in the real world, not all ballast or earth is the same color. It varies and so does this product. If you want a consistent color, then buy what you need and mix them together in one container. This stuff looks natural, because it is.

After being ejected out of a volcano, crushed black cinder/volcanic rock gets its appearance from the simultaneous rapid cooling and depressurization process. black Cinder Sand has small cysts, which is what causes it to be so light in weight. We crush these down to make 103 Black Cinder Ballast

Ties/Sleepers are placed on ballast to forms the trackbed upon which the track placed. It is packed between, below, and around the ties and ballasted to bear the load from the railroad ties, to facilitate drainage of water, and to keep down vegetation that might interfere with the track structure. The ballast also holds the track in place as the trains roll over it. It consists of crushed stone. Many modelers consider ballasting a chore, but one that is necessary to get the right look.

More on Ballast

The ballast for railway modelers comes in many sizes and colors. You will need to choose the size—this dependant on the scale of your model railway. Choose the color because of the location of your railway. Size is critical as over or under size ballast looks wrong. Colour is not as important as variations occurred around the country dependant on what local stone was available. It is possible to combine two colors to create the effect you require, but mixing the materials must be done accurately to allow you to combine the two colors again should you need more material. Choose the size and color that are appropriate for your scale and locale and complement the colors of your scenery. 


Brennan’s Better Ballast comes in two color gray and black. We can match to 130 for the gray and 103 for the black.
