He has dabbled in the model train industry, in product development, for quite some time, as his father was an avid model train enthusiast.

In 1995, our original SpeedTrak speedometer was designed and developed and customized by Robert for his father. His friends loved the product and that is when Robert decided to begin building them right at home.
