You do understand that a large part is being tunneled with a TBM? You would want an extra TBM to make a 3rd tunnel that may or may not get used?It seems that TBM subways predominantly use island platforms. As long as it's wide enough I don't see any problem. It's a different type of line for NYC, but I think that when it opens in 20 years people will see how much better it works than the existing lines. |
