To create a block, follow the steps described below.

1. Click on the Create block button () located at the end of the line with the required collection of routes. A similar button is located on the page with the blocks of each collection of routes ().
2. In the block creation window, specify its number (required field). The maximum length of the block number is 8 characters (numbers and letters).
3. Select the operation pattern in the drop-down list to the right of the number. As a result, the routes that form the collection are displayed below with a list of their schedules that correspond to the specified operation pattern. You can see only those routes that are switched on and have at least one schedule.
4. Specify the schedules that should be included in the block. To do this, successively click on the required schedules. The selected schedules have a light blue background and a blue frame. The schedules that cannot be selected due to the time intersections become inactive.
   
   
5. Save the block. The Save button becomes active only after selecting at least one schedule.

The schedules of which the block consists should meet the following requirements:

• The operation pattern should not be specified for schedules, or it should be uniform for all.
• One schedule can be included only in one block within a depot.
• There should not be any time intersections in the blocks of one route: the program does not allow you to save the created or edited block which overlaps other blocks.
