Potential visual bug when activating auto-working after a non-TORR-equipped signal has been passed 23/12/2020 at 02:31 #135090

Consider the following sequence of events:
1. There is a controlled signal. The signal is equipped with auto-working, but it is currently turned off. A route is set from the signal and the signal is green. The signal is not equipped with TORR.
2. A train passes the signal. As soon as the first TC in advance of the signal (typically, but not always, the overlap over the preceding signal) occupies, the signal turns red.
3. The train advances further forward. As soon as that first TC unoccupies, the signal stem turns from white to flashing white.
4. At this point, with the train still in the section (but occupying some further advanced circuits), press the button to enable auto working.

At this point, the signal will remain red (because the train is still occupying one of the TCs on the route), but the stem will stop flashing (because auto working has effectively restroked the route).

Because the signal stem is flashing, it is possible to push the auto working button while it is white or while it is black. If the auto working button is pushed while the stem is black, it stops flashing but remains black until the train moves further forward, all TCs are unoccupied, and the lamp changes to a colour other than red (at which point the stem changes from black to white, the colour I would expect). I would expect it to instead stop flashing and turn white immediately when the auto working button is pushed.

This is obviously very minor, but seems wrong. I have reproduced it in both Exeter and Edinburgh, so clearly not sim-specific (and that makes sense; I assume non-TORR-equipped signals and their rendering are implemented in core code, not reimplemented in each sim).

I don’t know what happens if you try the same thing on an approach released signal. I don’t have an example of an approach released auto workable route immediately at hand. I wonder if in that case, because the lamp doesn’t change colour even once the section is clear, perhaps the stem would remain black all the way until the next train approached the signal?

Can confirm that it is also reproducible in Plymouth, so presumably every SIM with a non-TORR option.

A bug similar to this, related to WH1 signal on Saltley, the white flashing "selected" indicator is not in the correct location, and does not disappear when deselecting or setting the route.

Different class of issue, already Mantis 0030930
