So just what happened this morning?

It didn't last long, they must have been updating it. When I saw it, everything was screwed!

First off, signalling problems in the Aldgate area around 0620. A couple of hours later, a tresspasser in the Aldgate area.

This was then followed by the member of staff being taken ill.

SeanB, they do have spare staff for such an eventuality, but not necessarily stationed at each and every station / cabin. The urgency in which the person concerned had to be rushed to hospital meant there was little option but to suspend the service for a time until someone could be ferried to the cabin. To the person's credit, despite being advised to the contrary, they worked to move potentially stalled trains whilst awaiting their ambulance. I am sure I can pass on your best wishes to the person concerned for both their speedy recovery and for their efforts prior to leaving - being as it seems you were merely stuck in front of a computer and not stuck on a train at the time.

Now. Back to the display. Normally it is standard practice to take each line in turn and display the "current" largest problem.

In the case you quote, the suspension of the H&C between Edgware Road and Hammersmith was the largest problem on the H&C at that time.

The displacement of stock which was diverted around the Circle meant that that line then went to a very regular/good service.

Other displaced stock was sent back along the H&C, also providing a "good service" for the H&C east of Edgware Road at least.

Just to contradict slightly what I said, the Met was shown as having 2 biggest problems. Late running due to the earlier signalling (and tresspass) problems was compounded by a failed train.

The District is self-explanatory.

Our Network Operations Centre (NOC) will normally select the most accurate / most relevant / easy to understand reasons for delays. Reasons are normally kept as brief as possible, mainly so that a "passer-by" looking at an information board won't have to wait too long to see which part of the line is affected (as the information scrolls across).

As for the map. Software glitch. You caught the site during mid-update. Who knows. I'm sure your button presses and clicks are not 100% all of the time. Some slack during particularly trying mornings such as this one would be nice.
