Planned, estimated and actual dates side by side
Tracking timelines mix three kinds of dates. Planned dates come from the original booking or schedule. Estimated dates are the current best guess and can change many times. Actual dates record a move that happened and rarely change afterward. A clear timeline shows the difference, often with outlined or gray markers for estimates. An estimated discharge is not a reason to send a truck, however close the date.
Upstream changes ripple downstream
Estimated events depend on everything upstream. If the vessel slips, every later estimate moves with it, often all at once in one carrier update. If a container is rolled or rerouted through another hub, estimates tied to the old plan may disappear and new ones appear. Carriers also tend not to estimate legs they do not control, such as an inland move the consignee arranges.
Learning from estimate-to-actual gaps
When an actual event posts, compare it with the last estimate shown before it. Consistently small gaps on a lane mean the estimates are usable for planning. Large or one-sided gaps, such as discharge landing a day after the estimate on most calls, are worth building into appointment and labor plans. Keep the comparison by terminal, because discharge speed can differ between terminals in the same port.
Example
A timeline for CMAU7029150 lists an estimated rail arrival in Memphis on Friday below the actual discharge at Norfolk; on Saturday, the estimate gives way to the actual arrival time.

Questions
What does Estimated Event mean?
An estimated event is a milestone shown with an expected date because it has not happened yet, such as an estimated discharge or rail arrival. When the move takes place, the carrier replaces it with an actual event and timestamp.
Why does my timeline show events with future dates?
Those are estimated events: the carrier's current plan for moves that have not happened yet. They turn into actual events, with recorded timestamps, once the carrier or terminal logs the move.
Can an estimated event be in the past?
Yes. If the estimated date passes and no actual event posts, the estimate is stale: the move either happened and has not been reported, or has not happened yet. Ask the carrier rather than assuming either.
