In outlier situations, they are probably weary about committing to any particular time, even if it's long. The uncertainty might be too great.

In which case, maybe we can get them to report confidence intervals on the arrival times?


The simple answer to why they didn't display anything was that they had no data. If there is a problem then they have to wait an indeterminate amount of time for it to clear. Then they realised that the first train through will be packed so rather than making it an all stations, they made it an express so it didn't stop but did get it out of the way.

Hopefully when they calculate delays they use the difference from when a train should have arrived until when the next arrived, but it wouldn't surprise me if trains just disappeared.


Always assume anyone compensated as a result of a metric is likely to try to game it.
