At http://cloud.tfl.gov.uk/TrackerNet/predictiondetailed/M/RKY for example, northbound Chiltern line trains show the destination of the train, e.g. Aylesbury or Aylesbury Vale Parkway. Yet, for some reason southbound trains show ‘Chiltern Trains’ as the destination.
Given that the northbound destination is derived from the DARWIN feed I believe, why can’t southbound trains return ‘London Marylebone’ or the timetabled destination of the train from the DARWIN feed in the ‘Destination’ tag as well?
