# Tracking Tab

The Tracking tab provides information about the email notifications we sent for the speed restriction.

In the example below the restriction was amended, so the default view shows the notifications sent for the current amendment (AICC 087A.26)

An Train Operating Company might have several addresses for receiving alerts but we just need Acknowledgement from one of them. The TOC is able to "subscribe" to the LORs that they operate on. We expect an Acknowledgement for every alert sent.

You can send a reminder email by clicking on the Issue Reminder button.

You can review what responses we got to the original ESR by clicking the button above the table (in this case AICC 087.26) -- you can't issue reminders since the original ESR has been superseded.
