I'm certain to be ignored/pushed aside if I comment on the post again, but train models don't get "discontinued" because there's no demand for particular models. Technically, there probably aren't even any "particular models".
This was pointed out by Michael Scabas, now with the Neptis foundation, who was one of the original ICTS developers with UTDC back in the '80s:

We question some of the assumptions in the Scarborough LRT BCA:
It is stated that as the ALRT Mark 1 vehicles “are no longer manufactured,” the line must be rebuilt to accommodate the larger Mark 2 vehicles. This is not correct. Transit cars are all “built to order,” and while there can be cost synergies in combining with another order, trains are not build on continuous assembly lines like cars or planes. Toronto’s replacement streetcars are a special design, to match the geometry of Toronto’s tracks. Certainly, TTC could procure replacement cars of the size and performance of the Mark 1 cars, if it wished to avoid the cost of rebuilding stations and curves. The cost per car would probably be higher, but total project cost might well be less. There is no evidence TTC or Metrolinx has considered this option, or enquired with Bombardier whether they would be prepared to build additional cars to the Mark 1 dimensions.

The only country I could think of with such a scale in its railway vehicle economy that manufacturers justify standardizing the designs is Japan. Maybe some European countries. But my point is there probably aren't even standardized designs at all.
The rolling stock brands you hear about (Alstom Metropolis, Bombardier MOVIA, etc.) are probably just existent for portfolio and marketing purposes. Even these product lines have to be modified extensively for
each train order. As an example, Bombardier calls some of their London Underground vehicles "MOVIA" metro trains, and yet they look nothing like the MOVIA vehicles in service in other cities like - say - Singapore; if the Underground cars weren't designed from scratch, than the original "MOVIA" designs required extensive modification to work on London's systems. Even ART has had this sort of thing happen - JFK AirTrain, Everline and Beijing ordered wider cars than the Mark IIs we see here on SkyTrain.
I can't say I know exactly how this works myself, but it's pretty clear that DMJ isn't even partly working off of any real knowledge - he's making up everything he says online. He reminds me of another popular "Donald" character with a last name of "Trump" - neither ever seem to have any facts or information on-hand.
Donald Malcolm Johnston is the Donald Trump of Metro Vancouver's transit issues.
