Alan - I was thinking the same thing as I glanced through the article. I got through some of it but then just started shaking my head. An ENTIRE article on a single CV!! How could anyone enjoy working with a system like that?
On a related note, I ran at a semi-local club for the first time a couple weeks ago. They were using Digitrax and had plenty of issues with losing control over locomotives, even while plugged in. Meanwhile I was happily running along with no problems...long trains, short trains, switching, multiple units up front with rear DPU's, etc. I ran ran for about 4 hours and the throttle was still kicking strong, though the battery indicated low (probably still had another 3 hours left). Needless to say there was some discussion of Railro and I let a few guys play around with it.
