# `departures(station, [opt])`

`station` must be in one of these formats:

```js
// a station ID, in a format compatible to the profile you use
'900000013102'

// an FPTF `station` object
{
	type: 'station',
	id: '900000013102',
	name: 'foo station',
	location: {
		type: 'location',
		latitude: 1.23,
		longitude: 3.21
	}
}
```

With `opt`, you can override the default options, which look like this:

```js
{
	// todo: products
	when:      new Date(),
	direction: null, // only show departures heading to this station
	duration:  10, // show departures for the next n minutes
	results: null, // max. number of results; `null` means "whatever HAFAS wants"
	subStops: true, // parse & expose sub-stops of stations?
	entrances: true, // parse & expose entrances of stops/stations?
	linesOfStops: false, // parse & expose lines at the stop/station?
	remarks: true, // parse & expose hints & warnings?
	stopovers: false, // fetch & parse previous/next stopovers?
	// departures at related stations
	// e.g. those that belong together on the metro map.
	includeRelatedStations: true,
	language: 'en' // language to get results in
}
```

## Response

*Note:* As stated in the [*Friendly Public Transport Format* `1.2.0`](https://github.com/public-transport/friendly-public-transport-format/tree/1.2.0), the `when` field includes the current delay. The `delay` field, if present, expresses how much the former differs from the schedule.

You may pass the `tripId` field into [`trip(id, lineName, [opt])`](trip.md) to get details on the vehicle's trip.

As an example, we're going to use the [VBB profile](../p/vbb):

```js
const createClient = require('hafas-client')
const vbbProfile = require('hafas-client/p/vbb')

const client = createClient(vbbProfile, 'my-awesome-program')

// S Charlottenburg
client.departures('900000024101', {duration: 3})
.then(console.log)
.catch(console.error)
```

The response may look like this:
