Funny thing, I have been working with telecom, computers and networks for decades, but have never, not once, seen FDDI implemented anywhere.
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.
