The Wind River Railroad is Ron Renner's creation in Denver. It's also loosely knit group of modelers that work on and operate the railroad - usually a few times a month. Back in late 2002, I volunteered to convert the signaling system to full CTC - and thus the MRBus project was born. Eventually I'll be putting up an entire case study on the design and implementation of signaling for the WR as an example of how to implement the system on other roads, but for now, here's a few photos.
