Warrants: The Warrant List

The Warrant List is a table of all Recorded Warrants. It also temporarily lists NX Warrants during the time they are in effect. The Warrant List window is a dispatchers sheet to run and control warranted trains.

You access the Warrant Table by selecting Warrant List from the Warrants menu of your Control Panel. For an overview discussion of Warrants, see Warrants.

Running Automated Trains

The throttle commands recorded in a Warrant are played back to run the train, but additional control of the train can be done through the choices provided by the Control/Status down down combobox. Note there are two ways to stop the train: Emergency Stop an immediate stop or Halt that slows the train to a stop smoothly. Once stopped, the Resumecommand will restart it, keeping the Warrant in effect. Move into Next Block is "repair" command should the train overrun a block and become "Lost". This command aligns the Warrant to the next block and restarts the train. The Abort command does an emergency stop and annuls the Warrant.

There are separate operations in the Warrant List table to reserve a Warrant route; the safer Allocate will not throw turnouts in blocks possibly occupied by trains or the Set (allocate and set turnouts). These operations do not have to be done before running an automated train. They are used to preview the route. An AutoRun operation can begin without them. The train will seek allocation and set turnouts as it proceeds on the route.

Automatic control of trains

Whenever a warranted train has permission to enter the next Block, the turnouts are reset to the route. This will correct any inadvertent setting of turnouts by other operators. If a warranted train does not have permission the enter a block, no turnouts for the route are thrown in the block or in the blocks beyond it.

"Stop" aspects of Signals, detection of occupancy or allocation to another warrant will deny permission for a warranted train to enter a block. Also, signals may prescribe speed restrictions. Whenever the train enters a block or is given a control command the warrant looks ahead for permission or speed restrictions. When this is detected, the warrant will suspend the warrant's throttle commands and issue throttle commands it calculates to ramp the train's speed smoothly to meet the required speed or stop just before entering the block.

When permission to enter a block is denied, a warranted train will not move. Clearing these conditions causing the a denial is cleared, the train will proceed automatically. The only thing that may override automatically proceeding is if the user has set the control to "Halt". The train will not move until the user sets "Resume".

Note: In order for warranted trains to respond to signal aspects, the Portals must be defined with Signal Heads or Signal Masts protecting the blocks they join, the train will modify the speed according to the appearance or aspect of the signal. When Warrant Speeds Are Modified has details about how Warrants modifyrecorded speeds.

When the Starting block is Unoccupied

If a Warrant is started and the starting block is not occupied, the Warrant will wait until the block is occupied. When occupation occurs the Warrant will is set to to wait for the user to use the "Resume" control to start the train. Note it is vital that the correct train occupies the starting block. The address specified in the Warrant, is the train that will begin moving.
