# DataSource
The DataSource object is used to specify additional GTFS (opens new window) (General Transit Feed Specification) and GTFS Realtime data sources, set as an array in the Map constructor option dataSources.
WARNING
Note that this is an experimental feature which is under development and is prone to change.
Currently, you must specify both a GTFS dataset and a GTFS Realtime feed to view vehicles moving along routes. Also, vehicles will not be displayed when Playback Mode is on.
