+ # In general, this function is meant to return feasible
+ # connections. However, cancelled connections may also be of
+ # interest and are also useful for logging cancellations.
+ # To satisfy both demands with (hopefully) little confusion and
+ # UI clutter, this function returns two concatenated arrays:
+ # actual connections (ordered by actual departure time) followed
+ # by cancelled connections (ordered by scheduled departure time).
+ # This is easiest to achieve in two separate loops.
+ #
+ # Note that a cancelled train may still have a matching destination
+ # in its route_post, e.g. if it leaves out $ds100 due to
+ # unscheduled route changes but continues on schedule afterwards
+ # -- so it is only cancelled at $ds100, not on the remainder of
+ # the route. Also note that this specific case is not yet handled
+ # properly by the cancellation logic etc.
