While the full report RAR 13-02 is not yet available at the NTSB's site, the preliminary report, from which the news report linked by Mr. Bart was drawn, is available:

If there ever was an instance to show why speculation regarding the cause of an incident should be avoided, it has to be this instant matter. No one here, and likely within the news media, and for that matter on the UP, were aware of the deficiency in the Engineer's vision. Inadequate crew rest does not appear to be a factor cited by the NTSB, although fatigue affects any body that has sleeping patterns abruptly changed. Former military and airline pilot Semaphore Sam certainly knows of this. The NTSB dismisses this matter with "insufficient evidence".
Naturally, it comes as no surprise that the Report gets like Polly The Parrot with regards to PTC; the problem of course is that as the "repetoire" of incidents, such as this, Red Oak, and of course Chatsworth, grows, the outcry will grow. This incident will likely cost UP "heap big wampum" that shippers will ultimately bear. But, other than passenger trains where we all know who will bear that costs, how will the cost to the freight industry be allocated amongst the stakeholders?
