I've been running battery/RailPro for about 2 years now. It's really a great system. I have 10 locos equipped with Railpro - 7 diesels and several steam. It's AZ hot, but I don't run when the wind is over 15mph (topples cars) or over 90 degrees (too hot for the operator). Nevertheless, my layout is maturing nicely - almost all the sunkinks have been smoothed out - I've learned not to use rail nails on curves, expect rail expansion and washouts. The terrain has been modified to allow for rain runoff with culverts and bridges. I deal with rodents, snakes, birds, coyotes. I sure would like to meet some others who run dead rail and operate, or meet up at another location to run - with Railpro/Battery operation, you can just show up and start running - no programming involved.
