== Overview ==

A Formation message indicates the number of coaches (vehicles), the class of seating and details about the toilets on board.  This information is maintained by train operators and is as accurate as the input they provide.

== Detail ==

Formation messages are contained in a 'scheduleFormations' element.

The example shown below is the formation for [[RID]] 201812217119801.  It describes a formation tagged as 201812217119801-001 - services may have more than one formation where they split and join en-route.

The set of coaches are listed in order with the first being at the front of the train, and the last being at the rear.  Coaches may be identified by number, or by letter - these identifiers are not necessarily alphabetically or numerically sequential.

The class of seating is also shown - Standard, First or Mixed.

Where a toilet is present in a particular coach, its status, the type of toilet (either Standard or Accessible) will be reported.  This is dependent on the operator of the train entering the details in to Darwin.
