Data Issue

aSIST receives train movement data that informs the various tools, such as indicating the next headcode on the aSIST Wrong Route Tool.

The Wrong Route Tool displays a health check to users, indicating when the last data message was received.

The TD lag will typically be within 10 seconds.

Overnight if less trains are running there may be no trains to report on the TD and users will see this lag increase. This is not a cause for concern.

After 45 seconds of no TD report the following status message will appear:

aSIST sends a 'heartbeat' every 60 seconds. Therefore in most cases the above message will disappear within a minute.

However in the event the message persists, there may be an issue with the incoming data feed.
