View the bottleneck information for a line

A line's bottleneck information is displayed at the top of its line pages, as highlighted below. In addition, the entity that is the bottleneck is indicated by the Bottleneck icon on its tile on the line's Entities tab, also highlighted below. If there are parallel entities at the bottleneck position, each entity will include the icon.

If the bottleneck cannot be determined by the system, then a Note indicator appears in the Bottleneck position of the line summary information, as shown below.

To see why the bottleneck cannot be determined, hover the cursor over the message icon. A tool tip appears that explains the issue.
