One tough part of the load handling is that if the L has increased capacity, this could, in some cases, just make congestion worse in many other areas because many people need to make at least 1 transfer for their trips. The tough problem isn't always capacity either. Small disruptions have cascading consequences. This is where I believe a lot of the limitations in service come from since there is rarely a day w/o a single problem. As many others have pointed out in the past, this can largely be traced to the topological properties of the subway lines. The MTA's insistence in growing just a few large bottlenecks rather than disperse them is telling of the problems we'll be living with for decades or centuries longer. At some point, I think the improved bus service initiatives are our only real hope of directly addressing the transportation problems in NYC. It might seem ludicrous in Manhattan but it certainly has its place and in the other boroughs, it can be a huge improvement when line selection is limited.
