I don't necessarily think that's a funny thing, you don't typically get the pedigree of every network your data traverses, unless you actually search for it.

I have worked hands on with a variety of systems and networks.  I have worked on telcom, cell networks, office LANs, cell networks, Rogers networks, in central offices, factories warehouses and more. I have seen a lot.

Toronto is a pretty late adopter of LRT tech, so in that sense, others have done our structural groundwork for us. I rode my first articulated urban LRT vehicle in Europe in 1967. The pilot LRT project for Toronto didn't materialize til 2001. Sure we had a couple of bendy buses but surface LRT was not on the Toronto transit radar at all; not for all those decades.


LRT used to be called "streetcars".  Toronto has had them for well over a century.

Wasn't that Air Canada system linked to the US carriers through SABRE Inc's frame relay system which allowed consumers to be able to access a computerized booking system using DTMF tones.


They connected to Sabre and eventually moved to it.  However, I had no experience with it.  The system at Front St. was based on a UNIVAC system and I worked on the communications front end, which ran on Collins computers.
