Transferring Issue is 7 Line Extension's Downfall

"Within urban rail, people transfer all the time. Perhaps the disutility of getting up while changing trains is not an issue when passengers do not expect to find a seat in the first place. Regional rail riders transfer as well, when the transfers are easy and there's no additional waiting time – in fact, setting up a timed transfer on a highly branched regional line increases the frequency on each branch, so any disutility from transferring is swamped by the more convenient schedule. What people don't normally do is ride a regional line that gets them almost to their job, and then take urban transit for the last mile."
