Overview
The train movements feed contains messages produced by TRUST. These messages are one of eight types, all in JSON format:
- 0001 - Train Activation
- 0002 - Train Cancellation
- 0003 - Train Movement
- 0004 - Unidentified Train
- 0005 - Train Reinstatement
- 0006 - Change of Origin
- 0007 - Change of Identity
- 0008 - Change of Location
Lifecycle
Before any action can be taken on a train, the schedule must be activated. An [Activation] message will be received, which will link a schedule to a 10-character train identity. This identity is referenced in all other message types, and there is no need to calculate it manually.
A train may be cancelled (either entirely or from a particular calling point onwards) through a [Train Cancellation] message, or start from a location other than the originating location through a [Change of Origin] message. A train may be reinstated after cancellation through a [Train Reinstatement] message.
One point to note - the [Change of Identity] message type is rarely seen. This is used when a train running under one class (e.g. a Class 4 freight with a train identity starting 4---) must run under a different class for some reason - usually because it must run at a lower speed due to the type of load it is carrying.
