All the TCX flights are based on the timetable from the link below. Some have just been added this week and have not any times loaded yet.
Not seen this bit of the TCX timetable before but similar to something that comes up on the main one. However I wouldn't rely on it because I have found it to be inaccurate before. It certainly doesn't fit with the full timetable for some destinations. I guess we will have to wait and see because as you say what are they going to use the 2 DE753s for because at the moment not even one is fully occupied.
