The eastbound Canyon Spirit is just passing by the hotbox detector (HBD) at milepost 22.6. The detector will provide an audible readout of information, including the number of recorded axles, train speed, and outdoor temperature. It would reveal that the train is slowly meandering along at 12 MPH. Email Questions or Comments to the Webmaster. User Comments (0) No comments posted yet. Click Here to add the first one!
