Warning Sign. Placed approximately 2 miles (with a couple exceptions) in advance of a temporary speed restriction or a work zone.redcrumbox wrote:What does a square yellow sign with a diagonal red line mean?
There were 2 switches behind the Amtrak train a very short distance. The one on the opposite side of the main from the incident can be seen having a derail. There is a signal circuit bungalow near both of the switches and this is usually an indicator of electric lock switches. There are no signals at the immediate location of the incident, but the line is TC (CTC) signalled territory.
I'm hearing there was a signal suspension in place, and by bulletin the maximum speeds are 59 passenger/49 freight, with the reported speed of 91 being 59 MPH. The bulletin issued with a signal suspension has standard wording to the effect that all switches are to be considered as lined for the main track within the limits of the suspension, and that TWC authority is used, meaning every train gets an EC-1 to operate through the suspension. The crew of the freight would have been required to note the handling of the switch on a Switch Position Awareness Form and report the initial throwing and final lining of the switch to the dispatcher and both crew members must initial the form.
The outward-facing camera of the lead unit of Q211 will most likely provide most of the information regarding what happened leading up to the incident.
