-- always available, by hash
Citizen.InvokeNative(0xCFE122EC635CC2B2, train, whistleSequence, p2, p3)
```

### JavaScript

```js
TriggerTrainWhistle(train, whistleSequence, p2, p3);

// by hash
Citizen.invokeNative('0xCFE122EC635CC2B2', train, whistleSequence, p2, p3);
```

### C#

```csharp
Function.Call((Hash)0xCFE122EC635CC2B2, train, whistleSequence, p2, p3);
```

- The name is a community guess and may change. If the named call is missing in your client build, use `InvokeNative` with the hash — it always works.
