Great ballast, but it took a while to get it

I ordered my ballast in early May, and subsequently there was a 10% off sale at ARM. I kept waiting for my ballast to arrive. Finally arrived about 6 weeks later. While I love the ballast, its perfect for SP, I was a bit disappointed with the service. I could have waited for the sale and saved a bit more. Probably the most frustrating thing is I got a number of emails from ARM during this time on modeling tips, but NONE that said hey, your order is delayed and we are working on it. Just saying....stuff like that is appreciated.

Not happy at all

I sent three email messages asking that the order be cancelled. No response to any of them. 5, almost 6 weeks after placing the order, items arrived. Don't need them anymore, but I'm not going to bother trying to return them because I'll probably never get a refund. I'll donate them to my local model railroading club.

Excellent product

Great company to deal with and they are fast to get the product to you. Its real and not crushed walnut shells. I use this as part of my recipe for my ballast. I mix this product with the Ho scale 1382 CSX Southern Pacific Wabash Gray and N scale 105 Pennsylvania Gray. This gives me what I think is the perfect mix and color of the ballast I am after. I also rinse the dust off to bring out the color even more.

No Such Product

I ordered Large "O" Scale ballast and I received HO Mainline. I expected something a lot "Larger". I called to get what I ordered and I was told that Large "O" and HO Mainline are the same size. I guess if you really want Large "O" scale you have to order G Scale.

Finest ballast on the market

I highly prefer using real rock products for ballast, as they always look realistic, compared to the dyed nut shells of competitors. This CSX color is exceptional and fit my needs perfectly!

After being ejected out of a volcano,  grey cinder/volcanic rock gets its appearance from the simultaneous rapid cooling and depressurization process. Grey Cinder Sand has small cysts, which is what causes it to be so light in weight. We crush it down to make 138 CSX SP Wabash Grey 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.
