Possible bug (small/minor) 17/07/2013 at 14:08 #47275

Hello, not sure if this merits attention as a bug, but it strikes me as slightly odd...

I am currently playing Euston in 80s mode, with the Euston 1980 draft V2.0.2a TT, running in a VMWare Windows Vista machine.

When I route any train down the Down Departure line, signal 72 turns red, and the route drops out (i.e. the signal stem is no longer illuminated) while TC101 is still occupied. As this TC is not in rear of the signal, this seems a little unusual. If I try to set a route from 72 to 83 while TC101 is occupied, the signal stem momentarily turns white, then reverts back to grey.

It doesn't seem to affect the running of the sim or be a safety-related matter, just something I noticed.

I cannot create your problem. All works fine for me. Do you have a saved snapshot of the incident?

The route dropping whilst the approach TC (T101) is a bit odd - usually you would expect it to (start to) drop once the train has unoccupied the approach TC and the advance TC (i.e. once T102 is clear). What's even odder is that the route takes a good few seconds to drop after the signal returns to red!

I can reproduce this on the released sim but not the current core code. I know that we changed the logic for routes with only one track circuit since Euston was released, so you've probably noticed one of the effects of the old code.

I'm only seeing it revert to red with both 101 and 102 occupied, not just 101. That's normal behaviour - this signal isn't last wheel replaced. Similarly, I'm only getting the stem grey->white->grey with both those TCs occupied. Is that what you're seeing? If so, there's nothing to worry about; it's just a quirk of the code.
