TSR

Temporary Speed Restriction (TSR) messages are sent once a week, on a Friday at 0600, and contain a snapshot of the TSRs published in the Weekly Operating Notice.

If your client is not connected at 0600 on a Friday, or does not have a durable subscription in place at this time, you will not receive the TSR messages.

TSR data is available on a single topic, TSR_ALL_ROUTE. Previously, the messages were split in a number of topics, listed below for historical purposes only:
