Train schedules are represented by a table in Lua. The table contains a list of entries where each entry has a single instruction and multiple conditions.
Each instruction and condition has a `data` table that stores specific data about the instruction or condition.

```lua
schedule = {
  cyclic = true, -- Does the schedule repeat itself after the end has been reached?
  entries = { -- List of entries, each entry contains a single instruction and multiple conditions.
    {
      instruction = {
        id = "create:destination", -- The different instructions are described below.
        data = { -- Data that is stored about the instruction. Different for each instruction type.
          text = "Station 1",
        },
      },
      conditions = {    -- List of lists of conditions. The outer list is the "OR" list
        {               -- and the inner lists are "AND" lists.
          {
            id = "create:delay", -- The different conditions are described below.
            data = { -- Data that is stored about the condition. Different for each condition type.
              value = 5,
              time_unit = 1,
            },
          },
          {
            id = "create:powered",
            data = {},
          },
        },
        {
          {
            id = "create:time_of_day",
            data = {
              rotation = 0,
              hour = 14,
              minute = 0,
            },
          },
        },
      },
    },
  },
}
```

## Instructions
| ID                                           | Description                     |
|----------------------------------------------|---------------------------------|
| [`"create:destination"`](#createdestination) | Move to a certain train station |
| [`"create:rename"`](#createrename)           | Change the schedule title       |
| [`"create:throttle"`](#createthrottle)       | Change the train's throttle     |

---
### `"create:destination"`
Moves the train to the chosen train station. This instruction must have at least one condition.

**Data**
- _text:_ `string` The name of the station to travel to. Can include * as a wildcard.

---
### `"create:rename"`
Renames the schedule. This name shows up on display link targets. This instruction cannot have conditions.

**Data**
- _text:_ `string` The name to rename the schedule to.

---
### `"create:throttle"`
Changes the throttle of the train. This instruction cannot have conditions.

**Data**
- _value:_ `number` The throttle to set the train to. Must be an integer within the range of [5..100].

---
## Conditions
Conditions are stored in a list of lists of conditions. The inner lists contain conditions that get `AND`'ed together. They must all be met for that group to be true.
The outer list contains the `AND`'ed groups of conditions that get `OR`'ed together. Only one of the groups needs to be true for the schedule to move onto the next instruction.
