Er, Why 10-cars? Designing the in-tunnel stations for anything less than
12 cars would be madness. I could understand leaving the out-tunnel
stations at eight cars (as present on the suburban GE) to save money and
get the project off the ground, or extend to 12 cars, but 10? This
requires almost as much work for half the benefit!

This reminded me of the trains I saw on the Paris Metro; the ones with
the full width intercar links.. would they make better use of available
space.
Possible?
