That's not taking a whole view of the system.
There is literately no reason to use anything but the Skytrain LIM cars, anywhere on the system. We could even use those for the "LRT" Surrey wants with a few changes.
For example:
1) We use the LIM Rolling stock on the Expo and Millennium Lines. We can keep extending these lines until there is a geographical limit. Eg SFU.
2) We could even use those at grade by retrofitting them to have pantograph style third rail support. Then the same cars can be used on both. The reason why this won't happen is because the grade separation allows for cheaper, lighter, smaller cars made of carbon-composite/fiberglass/aluminum/plastic. Trains that operate at grade must be heavier, thus they have much longer stopping distances.
3) The computer controlled system allows for cars to connect and disconnect and form 4-car or 2-car trains at will. We don't currently use this as far as I'm aware.
If you use the same rolling stock and have all your rail lines connected and interlining on at least one segment, you have no points of failure except total failure.
The light rail system will only have "complete failure" because there is no way to route trains anywhere else, no way to bypass an accident, and so forth. This is why the Light Rail system is inferior to perhaps an articulated trolley-bus system, which can drive around an accident, or be disconnected from the wires, driven/towed down another road and then reconnected on the other side, or if there is a power failure, run the diesel/CNG/hybrid buses down those roads.
Honestly I can find very little support for "this" LRT, because nobody can find any positive argument without a hole in it. eg "it's cheaper" , yes and the BRT option is even cheaper in capital cost, or the Skyrtain is cheaper in operational costs. Had the LRT project been independent and about reusing some other ROW, there would not be this level of gnashing of teeth over it. this kind of LRT would have made more sense to connect Surrey-Delta-Ladner because Delta and Ladner are never going to build 40-story towers surrounded by farmland. Any automated surface "LRT" should replace an existing bus route where there is little chance of train/car or train/pedestrian interaction. But maybe we shouldn't bother and let Uber/Lyft/etc deal with these edge cases and last-mile cases instead of running buses with low frequency.
Essentially every corner you can cut with this light-rail project, is going to be used so Surrey gets a third-rate transit system.
It would have been better for everyone in Metro Vancouver had those been two or three Skytrain lines that just met at King George, and expand all the way to White Rock and Abbotsford at "some point", even if it doesn't make sense to build currently. No you might not actually get on a train at Guildford and end up at downtown Vancouver, but a complete network might actually have Maple Ridge and Port Coquitlam as another route out of Surrey to get to at least Commercial/Broadway. Computer Control can determine where the trains need to go, and this is something we should be embracing, not complicating with some third-rate non-integrated system.
Once we start seeing more information about this LRT, we can pick it apart and have zero impact on it like we did with the Canada Line.
