Rick Rideout, the owner of Rick's Products, is one of the original C/MRI Users. He started out with the original UBEC approach using the very original design I/O cards using the 8255 ICs. Rick reports that, "After diving into the C/MRI implementation, I just couldn't believe how straightforward the application became. Set up one OS section all the rest are identical except for a few number changes."
To top it all off, the system works today as good as the day it was installed nearly 15 years ago. Besides being tied into the CTC panel and controlling the trackside signals, Rick reports that "The C/MRI also drives his fast-time clocks and drives a speedometer readout at each of his OS sections." To accomplish this, the C/MRI measures the time it takes a train to traverse through an OS section and knowing the length of the OS section it computes the train speed and drives a numeric LED readout at the OS location. It is true, once you have a C/MRI installed on your railroad you will be amazed at the additional applications you will dream up and implement.
