New York Railway Supply was started by Doug Deist in the mid 90’s. In 2003 Jack Walton acquired the product line and has been running it ever since. The PTC3 has migrated to the PTC4 to keep up with modern technologies as they become available. We have shrunk the system to one board and have continued to modify and add to the firmware and hardware. Looking forward to continuing our nice little product for a long time. I have spent my life doing software/hardware design and this lets me do a little bit of everything I’ve spent my career doing.
