During this incident, 2 successive train control handovers were conducted in a fashion that did not detect the presence of all train movements, and on each occasion the trainee, then the incoming controller, assumed the responsibility for the desk before they had acquired full situational awareness of the status of all movements within their area. The area of train control would benefit from some form of external review of processes to identify if these practices were confined to this one event or symptomatic of a wider systemic issue.
