I've was recently told that exports are also creating a capacity problem at POLA-POLB. Increased exports and blocking problems with export bound container trains are creating landside confusion and capacity problems as trains are arriving.

It is my understanding, from what I was told, that many of these improper blocking problems create the need to do unnecessary switching and draying, sucking up limited switching capacity in the Ports, reducing the effectiveness of the significant investment in on-dock loading.

This "export" problem also has the effect of further delaying in-bound traffic, as well. The need for switching and inadequate capacity to do so, is also starting to cause trains to begin to backup, eating up mainline and siding capacity approaching LA, too.
