On the southeast edge of Big Ten Curve, there is a solar-powered weather station setup. The weather station includes an anemometer, which reports the wind speed to UP's headquarters back in Omaha. If wind speeds are too high, UP will issue a 10 MPH slow order around Big Ten Curve. Email Questions or Comments to the Webmaster. User Comments (0) No comments posted yet.
