The whole attempt to tie the term 'SkyTrain' to the propulsion technologies (rather than its proper definition of being, essentially, the name of our system) was a sort of informal campaign by various groups/individuals who essentially wanted us to stop building SkyTrain and look at conventional LRT systems.
I don't know who said it first, but the whole idea that we could only take in one manufacturer had essentially been widely accepted/unopposed by anyone for decades (see:
2006,
2008,
2011,
2016). Nobody could figure out the actual truth (not even the old
UBC SkyTrain group), so "SkyTrain is a proprietary technology" became widely accepted as fact.
I took some role to dispel the myth by coming in with SkyTrain for Surrey and using that platform to make people aware of the existence of non-Bombardier systems. (I had, of course, just come out of spending a year in Japan and discovering LIM rails in the subways in Fukuoka, Osaka, and the just-opened system in Sendai).
But even with me doing that, it still took
until 2019 for TransLink and Bombardier to finally make a public statement about it and clearly say to the public, "no, SkyTrain is not propietary, there are no patents held by SNC-Lavalin, there is no exclusivity to Bombardier for building our trains", and until the following year for us to see that there were indeed multiple bidders for that big SkyTrain car contract.
Things are a lot better in 2024 but in essence we are still recovering from having our long term plans affected by decades and decades of unhampered libellous misinformation.
