That is quite enough, thank you! Just because I do not agree with you on how the project should be executed does not give you a right to suggest I am somehow not a transit advocate, or question my motives. Everyone here clearly has the city's best interests in mind, we just have different visions on how to get there. Casting aspersions on one's motives derails the discussion and gives the forum a bad name.
As for your actual argument, that line of thinking is exactly what we don't need in transit (except for the part about off the shelf designs, but I highly doubt designing a 75 foot subway car that is otherwise standard in the parts it uses is an insurmountable task).
Transit is not supposed to be cutting edge, it's supposed to be functional. If the design still works (and manifestly it does, otherwise the TTC would have gone back to the drawing board for the proposed T1 replacement rather than building on more of the same), and there is no urgent argument in favour of doing so, such as wheelchair accessibility or energy efficiency, what need is there to change it, exactly? I'm not saying that this is what's going to happen to the Hitachi trains, but progress for progress' sake is what got us white elephants like the SRT. Ask any rider on the next subway platform you step on and I'm sure they'll agree, provided they are not Gadgetbahn enthusiasts, that having a proven type of vehicle, albeit with the regular comforts passengers have come to expect in the 21st century, would be superior to having something that is cutting edge and doesn't work.
And I don't see where you are getting the idea that this "technology" is outdated, anyway, considering I haven't actually said anything at all about the type of technology that should be used on the trains, just their length. If the new Hitachi things were the dimensions of a TTC subway car, but kept everything else intact, they'd hardly be out of date.
And why stop there? There is nothing about subway trains that is modern to begin with, they have been around for more than 150 years. If pushing technology to its limits is the goal here, why not make the Ontario Line into a maglev or something? Or ask Elon Musk to build his Hyperloop in its place?
Progress for progrsss' sake is bad.
