Define Convoy
Description
This form is used to define a convoy of vehicles. There is no limit to the number of convoys that can be defined.
A uniform convoy consists of a series of identical vehicles with equal separation between them. A non-uniform convoy consists of a series of identical or mixed type vehicles with mixed separation.
Outline Procedure
This form is accessed from Data | Define Convoy in the main menu.
Click on the + (Add new convoy) button to define a new convoy, or select an existing convoy to edit from the field labeled 'Name'. For a new convoy type in a name in the 'Name' field.
From the field labeled 'Convoy Type' select uniform or non-uniform. For a uniform convoy specify the number of vehicles required and fill in the data required in the first row of the table. The table contains an unlimited number of rows when defining a non-uniform convoy.
The convoy is defined from left to right. The convoy is set out so that, for each vehicle, the point midway between the outermost tracks is aligned.
