Xx legend xX Red is short waiting time Yellow is long waiting time

Service gets going – good performance for main routes
Still improving

Let’s drill down to one station. What’s its expected profile (grey) What are the recent conditions (brown) Last 24hrs was generally better than expected, but what went wrong at 1400-1500?
So we can do a
For last last hour, how has performance been, relatively to expected Green higher freq Orange – as expected Ref lower freq - problems
