I can't tell if this is sarcasm or if you are seriously incredulous that a signalling system system can do what it is designed to do, to the point that nothing other than commercially protected excerpts of code and scans of wiring diagrams will convince you.
- Do you have some kind of insider knowledge that puts you in a better informed position than the experts consulted by professional journalists at Canada's highest circulation newspaper?
- Is there some reason that trains would be unable to close their own doors automatically, a function performed safely and without human intervention by literally every elevator and commercial building in the world?
- Is there a reason that Andy Byford, the outgoing CEO of the TTC who no longer has any stake in internal TTC politics, would be part of a conspiracy to hide this?
Until you are able to answer those basic questions, maybe you shouldn't challenge the reference that you asked for.
Just to recap:
Level of evidence needed by other people:
Something akin to what you would expect in an air crash investigation
Level of evidence needed by Dan:
Just a vague sentiment that the reference is wrong, without any articulation of why that could be the case.
Here is your goddamned reference, unless internally commissioned documentation isn't acceptable and I need to hack into TTC archives.
