Fast forward would (try to) do the majority of the system in 10 years, not just a single line in 10 years. As with all public works projects, it will face delays of course, but we shouldn't use that as an excuse to not do anything. People would rather have a continuously shitty system forever instead of being inconvenienced for a few years and getting a massively better system for decades to come unfortunately.
To bring this thread back to topic: with Kawasaki having issues with getting the M9 out on time, and with how relatively large the R211 order is, I'm assuming the chance of Kawasaki getting the R262 order is pretty low? With Bombardier (and potentially Kawasaki) out, what does that leave us with? Alstom and CRCC? Has Siemens ever bid on a NYCT rolling stock order?
