I process arrivals for the district line using the ‘/line/district/arrivals’ endpoint, getting arrivals for all stops. However, some stops seem to consistently bring back no arrivals.
Some of these stops: Bayswater, Notting Hill Gate, Mile End, Becontree. There are probably more.
I notice that the TFL arrivals page for these stops also doesn’t show any data
Does this mean there is a problem with the data source?
In terms of T5, I would imagine that suffers from being a terminal station and train predictions only appear when a train goes into service (i.e. a few moments before it leaves T5 eastbound)
