Oak Tree Systems' hardware, including the IO-48, IO-24, O-48, and CBC-8, are fully supported by Freiwald Software's Railroad and Co. Because the software products are readily available by download over the internet, we no longer carry these products.  Several levels of Railroad and Co. Traincontroller are available, as well as other products, at www.freiwald.com.

Support for these products is available directly from the manufacturer's web site.
